In our design, we leverage recent lessons learned from design vulnerabilities in security protocols for other wireless networks such as 802.11b and GSM. Conventional security protocols tend to be conservative in their security guarantees, typically adding 16--32 bytes of overhead. With small memories, weak processors, limited energy, and 30 byte packets, sensor networks cannot afford this luxury. TinySec addresses these extreme resource constraints with careful design; we explore the tradeoffs among different cryptographic primitives and use the inherent sensor network limitations to our advantage when choosing parameters to find a sweet spot for security, packet overhead, and resource requirements. TinySec is portable to a variety of hardware and radio platforms. Our experimental results on a 36 node distributed sensor network application clearly demonstrate that software based link layer protocols are feasible and efficient, adding less than 10% energy, latency, and bandwidth overhead.", "proceedingsTitle": "Proceedings of the 2nd international conference on Embedded networked sensor systems", "conferenceName": "", "publisher": "ACM", "place": "Baltimore, MD, USA", "date": "2004", "eventPlace": "", "volume": "", "issue": "", "numberOfVolumes": "", "pages": "162-175", "series": "", "seriesNumber": "", "DOI": "10.1145/1031495.1031515", "ISBN": "1-58113-879-2", "citationKey": "", "url": "http://portal.acm.org/citation.cfm?id=1031495.1031515", "accessDate": "2010-05-18T19:16:17Z", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "TinySec", "language": "", "libraryCatalog": "ACM", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "link layer security", "type": 1 }, { "tag": "sensor network security", "type": 1 } ], "collections": [ "NAADN6JB" ], "relations": {}, "dateAdded": "2010-05-18T19:16:17Z", "dateModified": "2010-05-18T19:16:17Z" } }, { "key": "CTGSSBD5", "version": 1, "library": { "type": "group", "id": 10763, "name": "msu8990sensornets", "links": { "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/10763/items/CTGSSBD5", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets/items/CTGSSBD5", "type": "text/html" } }, "meta": { "createdByUser": { "id": 55640, "username": "bradreaves", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/bradreaves", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "CTGSSBD5", "version": 1, "itemType": "webpage", "title": "MICAz 2.4GHz -

The first generation of sensor networks for structural monitoring are likely to be data acquisition systems that collect data at a single node for centralized processing. In this paper, we discuss the design and evaluation of a wireless sensor network system (called Wisden for structural data acquisition. Wisden incorporates two novel mechanisms, reliable data transport using a hybrid of end-to-end and hop-by-hop recovery, and low-overhead data time-stamping that does not require global clock synchronization. We also study the applicability of wavelet-based compression techniques to overcome the bandwidth limitations imposed by low-power wireless radios. We describe our implementation of these mechanisms on the Mica-2 motes and evaluate the performance of our implementation. We also report experiences from deploying Wisden on a large structure.", "proceedingsTitle": "Proceedings of the 2nd international conference on Embedded networked sensor systems", "conferenceName": "", "publisher": "ACM", "place": "Baltimore, MD, USA", "date": "2004", "eventPlace": "", "volume": "", "issue": "", "numberOfVolumes": "", "pages": "13-24", "series": "", "seriesNumber": "", "DOI": "10.1145/1031495.1031498", "ISBN": "1-58113-879-2", "citationKey": "", "url": "http://portal.acm.org/citation.cfm?id=1031495.1031498&coll=portal&dl=ACM&CFID=87402192&CFTOKEN=45646629", "accessDate": "2010-04-22T15:16:24Z", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ACM", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "sensor network", "type": 1 }, { "tag": "structural health monitoring", "type": 1 }, { "tag": "wisden", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2010-04-22T15:16:24Z", "dateModified": "2010-04-22T15:16:24Z" } }, { "key": "CWJP73SV", "version": 1, "library": { "type": "group", "id": 10763, "name": "msu8990sensornets", "links": { "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/10763/items/CWJP73SV", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets/items/CWJP73SV", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/10763/items/AD4AAFT9", "type": "application/json" } }, "meta": { "createdByUser": { "id": 55640, "username": "bradreaves", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/bradreaves", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "CWJP73SV", "version": 1, "parentItem": "AD4AAFT9", "itemType": "attachment", "linkMode": "imported_url", "title": "ACM Full Text PDF", "accessDate": "2010-04-22T15:14:37Z", "url": "http://portal.acm.org/ft_gateway.cfm?id=1031521&type=pdf&coll=portal&dl=ACM&CFID=85481984&CFTOKEN=49670296", "note": "", "contentType": "application/pdf", "charset": "", "filename": "Szewczyk et al. -

This paper focuses on nodal and network performance, with an emphasis on lifetime, reliability, and the the static and dynamic aspects of single and multi-hop networks. We compare the results collected to expectations set during the design phase: we were able to accurately predict lifetime of the single-hop network, but we underestimated the impact of multi-hop traffic overhearing and the nuances of power source selection. While initial packet loss data was commensurate with lab experiments, over the duration of the deployment, reliability of the backend infrastructure and the transit network had a dominant impact on overall network performance.

For example, in a number of application domains including homeland security, environmental monitoring, and surveillance for military operations, a network's ability to efficiently manage power consumption is extremely critical because direct user intervention after initial deployment is severely limited. In these settings, limited battery life gives rise to the basic coordination problem of maintaining coverage while maximizing the network's lifetime. In this paper, we propose a distributed scheme for efficient power management in sensor networks that is guaranteed to identify suboptimal topologies in an online fashion. Our scheme is based on a general (game-theoretic) mathematical structure that induces a natural mapping between the informational layer and the physical layer. We provide sufficient conditions for the convergence of the algorithm to a pure Nash equilibrium and characterize the performance of the algorithm in terms of coverage. We also present encouraging performance results on a MicaZ testbed as well as on large-scale topologies (obtained via simulation).", "publicationTitle": "OPERATIONS RESEARCH", "publisher": "", "place": "", "date": "October 19, 2007", "volume": "", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "opre.1070.0435", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1287/opre.1070.0435", "citationKey": "", "url": "http://or.journal.informs.org/cgi/content/abstract/opre.1070.0435v1", "accessDate": "2010-03-26T00:46:01Z", "PMID": "", "PMCID": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "HighWire", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "RKQGNPA3" ], "relations": {}, "dateAdded": "2010-03-26T00:46:01Z", "dateModified": "2010-03-26T00:46:01Z" } }, { "key": "FWUU43T5", "version": 1, "library": { "type": "group", "id": 10763, "name": "msu8990sensornets", "links": { "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/10763/items/FWUU43T5", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets/items/FWUU43T5", "type": "text/html" } }, "meta": { "createdByUser": { "id": 55640, "username": "bradreaves", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/bradreaves", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "FWUU43T5", "version": 1, "itemType": "attachment", "linkMode": "imported_url", "title": "ClockSyncWSNsurvey.pdf", "accessDate": "2010-03-08T04:50:42Z", "url": "http://www.cs.uic.edu/~ajayk/ext/ClockSyncWSNsurvey.pdf", "note": "", "contentType": "application/pdf", "charset": "", "filename": "ClockSyncWSNsurvey.pdf", "md5": "c71f763ce3544321159a5d89bb278aaa", "mtime": 2147483647, "tags": [], "collections": [], "relations": {}, "dateAdded": "2010-03-08T04:50:42Z", "dateModified": "2010-03-08T04:50:45Z" } }, { "key": "H5RJ82JZ", "version": 1, "library": { "type": "group", "id": 10763, "name": "msu8990sensornets", "links": { "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/10763/items/H5RJ82JZ", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets/items/H5RJ82JZ", "type": "text/html" } }, "meta": { "createdByUser": { "id": 55640, "username": "bradreaves", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/bradreaves", "type": "text/html" } } }, "creatorSummary": "Ganeriwal et al.", "parsedDate": "2003", "numChildren": 0 }, "data": { "key": "H5RJ82JZ", "version": 1, "itemType": "conferencePaper", "title": "Timing-sync protocol for sensor networks", "creators": [ { "creatorType": "author", "firstName": "Saurabh", "lastName": "Ganeriwal" }, { "creatorType": "author", "firstName": "Ram", "lastName": "Kumar" }, { "creatorType": "author", "firstName": "Mani B.", "lastName": "Srivastava" } ], "abstractNote": "Wireless ad-hoc sensor networks have emerged as an interesting and important research area in the last few years. The applications envisioned for such networks require collaborative execution of a distributed task amongst a large set of sensor nodes. This is realized by exchanging messages that are time-stamped using the local clocks on the nodes. Therefore, time synchronization becomes an indispensable piece of infrastructure in such systems. For years, protocols such as NTP have kept the clocks of networked systems in perfect synchrony. However, this new class of networks has a large density of nodes and very limited energy resource at every node; this leads to scalability requirements while limiting the resources that can be used to achieve them. A new approach to time synchronization is needed for sensor networks.In this paper, we present Timing-sync Protocol for Sensor Networks (TPSN) that aims at providing network-wide time synchronization in a sensor network. The algorithm works in two steps. In the first step, a hierarchical structure is established in the network and then a pair wise synchronization is performed along the edges of this structure to establish a global timescale throughout the network. Eventually all nodes in the network synchronize their clocks to a reference node. We implement our algorithm on Berkeley motes and show that it can synchronize a pair of neighboring motes to an average accuracy of less than 20ms. We argue that TPSN roughly gives a 2x better performance as compared to Reference Broadcast Synchronization (RBS) and verify this by implementing RBS on motes. We also show the performance of TPSN over small multihop networks of motes and use simulations to verify its accuracy over large-scale networks. We show that the synchronization accuracy does not degrade significantly with the increase in number of nodes being deployed, making TPSN completely scalable.", "proceedingsTitle": "Proceedings of the 1st international conference on Embedded networked sensor systems", "conferenceName": "", "publisher": "ACM", "place": "Los Angeles, California, USA", "date": "2003", "eventPlace": "", "volume": "", "issue": "", "numberOfVolumes": "", "pages": "138-149", "series": "", "seriesNumber": "", "DOI": "10.1145/958491.958508", "ISBN": "1-58113-707-9", "citationKey": "", "url": "http://portal.acm.org/citation.cfm?id=958508", "accessDate": "2010-03-08T04:50:20Z", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ACM", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "clock drift", "type": 1 }, { "tag": "medium access control", "type": 1 }, { "tag": "packet delay", "type": 1 }, { "tag": "sensor networks", "type": 1 }, { "tag": "time synchronization", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2010-03-08T04:50:20Z", "dateModified": "2010-03-08T04:50:20Z" } }, { "key": "58NP9H5H", "version": 1, "library": { "type": "group", "id": 10763, "name": "msu8990sensornets", "links": { "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/10763/items/58NP9H5H", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets/items/58NP9H5H", "type": "text/html" } }, "meta": { "createdByUser": { "id": 55640, "username": "bradreaves", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/bradreaves", "type": "text/html" } } }, "creatorSummary": "Mathur et al.", "parsedDate": "2006", "numChildren": 0 }, "data": { "key": "58NP9H5H", "version": 1, "itemType": "conferencePaper", "title": "Ultra-low power data storage for sensor networks", "creators": [ { "creatorType": "author", "firstName": "Gaurav", "lastName": "Mathur" }, { "creatorType": "author", "firstName": "Peter", "lastName": "Desnoyers" }, { "creatorType": "author", "firstName": "Deepak", "lastName": "Ganesan" }, { "creatorType": "author", "firstName": "Prashant", "lastName": "Shenoy" } ], "abstractNote": "Local storage is required in many sensor network applications, both for archival of detailed event information, as well as to overcome sensor platform memory constraints. While extensive measurement studies have been performed to highlight the trade-off between computation and communication in sensor networks, the role of storage has received little attention. The storage subsystems on currently available sensor platforms have not exploited technology trends, and consequently the energy cost of storage on these platforms is as high as that of communication. Current flash memories, however, offer a low-priced, high-capacity and extremely energy-efficient storage solution.In this paper, we perform a comprehensive evaluation of the active and sleep-mode energy consumption of available flash-based storage options for sensor platforms. Our results demonstrate more than a 100-fold decrease in per-byte energy consumption for surface-mount parallel NAND flash in comparison with the MicaZ on-board serial flash. In addition, this dramatically reduces storage energy costs relative to communication, introducing a new dimension in traditional computation vs communication trade-offs. Our results have significant ramifications on the design of sensor platforms as well as on the energy consumption of sensing applications. We quantify the potential energy gains for two commonly used sensor network services: communication and in-network data aggregation. Our measurements show significant improvements in each service: 50-fold and up to 10-fold reductions in energy for communication and data aggregation respectively.", "proceedingsTitle": "Proceedings of the 5th international conference on Information processing in sensor networks", "conferenceName": "", "publisher": "ACM", "place": "Nashville, Tennessee, USA", "date": "2006", "eventPlace": "", "volume": "", "issue": "", "numberOfVolumes": "", "pages": "374-381", "series": "", "seriesNumber": "", "DOI": "10.1145/1127777.1127833", "ISBN": "1-59593-334-4", "citationKey": "", "url": "http://portal.acm.org/citation.cfm?id=1127777.1127833&coll=portal&dl=ACM&CFID=80561153&CFTOKEN=15614186", "accessDate": "2010-03-05T05:30:41Z", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ACM", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "embedded systems", "type": 1 }, { "tag": "energy efficiency", "type": 1 }, { "tag": "flash memory", "type": 1 }, { "tag": "sensor networks", "type": 1 }, { "tag": "storage", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2010-03-05T05:30:41Z", "dateModified": "2010-03-05T05:30:41Z" } }, { "key": "3CDHN3MT", "version": 1, "library": { "type": "group", "id": 10763, "name": "msu8990sensornets", "links": { "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/10763/items/3CDHN3MT", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/msu8990sensornets/items/3CDHN3MT", "type": "text/html" } }, "meta": { "createdByUser": { "id": 55640, "username": "bradreaves", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/bradreaves", "type": "text/html" } } }, "creatorSummary": "Luo et al.", "parsedDate": "2006", "numChildren": 0 }, "data": { "key": "3CDHN3MT", "version": 1, "itemType": "journalArticle", "title": "EnviroSuite: An environmentally immersive programming framework for sensor networks", "creators": [ { "creatorType": "author", "firstName": "Liqian", "lastName": "Luo" }, { "creatorType": "author", "firstName": "Tarek F.", "lastName": "Abdelzaher" }, { "creatorType": "author", "firstName": "Tian", "lastName": "He" }, { "creatorType": "author", "firstName": "John A.", "lastName": "Stankovic" } ], "abstractNote": "Sensor networks open a new frontier for embedded-distributed computing.

In this paper, we consider the novel distributed database workload characteristics of these services, and present IDP, an online, adaptive data placement and replication system tailored to this workload. Given a hierarchical database, IDP automatically partitions it among a set of networked hosts, and replicates portions of it. IDP makes decisions based on measurements of access locality within the database, read and write load for individual objects within the database, proximity between queriers and potential replicas, and total load on hosts participating in the database. Our evaluation of IDP under real and synthetic workloads, including flash crowds of queriers, demonstrates that in comparison with previously-studied replica placement techniques, IDP reduces average response times for user queries by up to a factor of 3 and reduces network traffic for queries, updates, and data movements by up to an order of magnitude.", "proceedingsTitle": "Proceedings of the 4th conference on USENIX Conference on File and Storage Technologies - Volume 4", "conferenceName": "", "publisher": "USENIX Association", "place": "San Francisco, CA", "date": "2005", "eventPlace": "", "volume": "", "issue": "", "numberOfVolumes": "", "pages": "4-4", "series": "", "seriesNumber": "", "DOI": "", "ISBN": "", "citationKey": "", "url": "http://portal.acm.org/citation.cfm?id=1251028.1251032&coll=portal&dl=ACM&CFID=76202982&CFTOKEN=47782796", "accessDate": "2010-02-15T03:32:46Z", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ACM", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2010-02-15T03:32:46Z", "dateModified": "2010-02-15T03:32:46Z" } } ]
