We present new techniques that improve NGKD performance while also improving the resilience of TWSNs against attacks that combine node capture with message interception. This is accomplished without introducing additional communications or heavy-weight cryptographic computations that would degrade sensor network performance and reduce node lifetime. Our iterated keying algorithm allows networks to initialize and add new members as rapidly as any algorithm available, but with substantially greater deletion efficiency than in current practice. Our simulations demonstrate that, compared to techniques currently used in DoD research prototypes, our algorithm can reduce deletion bandwidth and energy costs by nearly 50 percent.","PeriodicalId":293243,"journal":{"name":"2007 IEEE Sarnoff Symposium","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129110593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The diversified Internet architecture requires effective collaboration among heterogeneous network domains to support various application requirements. One of the challenges to achieve this objective lies in enabling network domain collaboration and network-application interaction without exposing the internal structure and implementation details of each domain. The service-oriented architecture has been successful in the grid computing and Web services areas to address the problem of inter-domain resource sharing to support various applications. In this paper, we explore application of the service-oriented idea in networking area to support the diversified Internet. We specifically investigate service-oriented network abstraction and discovery. We propose an approach for network service description and develop a technique for discovering the appropriate network services that meet performance requirements. We also discuss a system structure for implementing the technologies developed in this paper.","PeriodicalId":293243,"journal":{"name":"2007 IEEE Sarnoff Symposium","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124112498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We study individually optimal user-network association in an integrated WLAN and UMTS hybrid cell. The association problem is formulated within a non-cooperative game framework. In the formulation, mobile arrivals are assumed to follow the Poisson process and each mobile considers its average service time in each network as the decision criteria to connect to either of the WLAN or UMTS networks. We seek to compute the optimal association or decision policy that achieves the Nash equilibrium. For this we develop a generic system of linear equations for estimating the average service time of a mobile. This system is then solved assuming a particular model for the WLAN and UMTS networks and we explicitly compute the optimal association policy that is observed to possess a descending staircase curve structure.","PeriodicalId":293243,"journal":{"name":"2007 IEEE Sarnoff Symposium","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121392224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel method called Alamouti blockwise analytical matrix inversion (ABAMI) is proposed for the inversion of large complex matrices that are based on Alamouti sub-blocks. Another method using a variant of Givens rotation is proposed for fast QR decomposition of this kind of matrices. Our solutions significantly reduce the number of operations which makes them more than 4 times faster than several other solutions in the literature. Furthermore, compared to fixed function VLSI implementations, our solution is more flexible and consumes less silicon area because the hardware is programmable and it can be reused for many other operations such as filtering, correlation and FFT/IFFT. Besides the analysis of the general computational complexity based on the number of basic operations, the computational latency is also measured in clock cycles based on the conceptual hardware for real-time matrix manipulations.","PeriodicalId":293243,"journal":{"name":"2007 IEEE Sarnoff Symposium","volume":"11 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114340124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence and collaborations with others, those malicious behaviors could halt WSNs. In this paper, the WSNs will be first categorized into three types in accordance to the way that data are collected. After a succinct summarization of each data gathering scheme, a comprehensive survey on security problems will be presented. Finally, some general design guidelines against typical attacks along with our proposals in WSNs will be provided.

Relatively less important components such as the information for the values of pixels are transmitted with lower overhead.

Conventionally, data packets that are not correctly detected are usually dropped. These dropped packets can be used to help data packet detection. By exploiting all the retransmitted packets, data packets can be correctly detected with higher probability. The proposed approach provides a way to detect the packet by canceling out the known interference and summing up the residue received signal for all the retransmissions of a packet. Higher throughput is obtained with this approach. Regarding fairness, our proposed approach performs better than the power control approach. An algorithm is brought out to find the transmission probabilities for all the users to get maximum throughput with control of fairness. Higher power efficiency, defined as a new measure to estimate cross-layer performance, is achieved. Hence power control, which is critical in wireless communications, can be relaxed with the proposed approach.","PeriodicalId":293243,"journal":{"name":"2007 IEEE Sarnoff Symposium","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129005377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
