Energy efficient link layer jamming attacks have proven to be a real threat to wireless sensor networks. This type of attacks is able to prevent network communication for relatively long periods as it does not spend a lot of power while jamming. This paper proposes and evaluates two modifications to the Lightweight Medium Access Control (LMAC) [3] protocol. The first is Data Packet Separation Slot Size Randomization (DS-SSR); the second is Round Robin (RR) slot size assignment. The paper shows that (DS-SSR) can increase the WSN resistance against the Energy efficient denial of service link layer jamming attacks. The paper also shows that employing RR slightly eliminates the negative impact on the network throughput when using countermeasures against energy efficient jamming. Two measures are used to evaluate the resistance of the proposed protocol against the attack: lifetime advantage and censorship rate. Experimental results show that about 8 % reduction of the attacker lifetime advantage can be achieved with DS-SSR LMAC compared to other countermeasure. Furthermore, results show that the censorship rate of our proposed protocol was similar to the other countermeasures.","PeriodicalId":375277,"journal":{"name":"2011 9th IEEE/ACS International Conference on Computer Systems and Applications (AICCSA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114648597","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 this paper, we present the design and implementation of an LU factorization using tile algorithm that can fully exploit the potential of such platforms in spite of their complexity. We use a methodology derived from previous work on Cholesky and QR factorizations. Our contributions essentially consist of providing new CPU/GPU hybrid LU kernels, studying the impact on performance of the looking variants as well as the storage layout in presence of pivoting, tuning the kernels for two different machines composed of multiple recent NVIDIA Tesla S1070 (four GPUs total) and Fermi-based S2050 GPUs (three GPUs total), respectively. The hybrid tile LU asymptotically achieves 1 Tflop/s in single precision on both hardwares. The performance in double precision arithmetic reaches 500 Gflop/s on the Fermi-based system, twice faster than the old GPU generation of Tesla S1070. We also discuss the impact of the number of tiles on the numerical stability. We show that the numerical results of the tile LU factorization will be accurate enough for most applications as long as the computations are performed in double precision arithmetic.","PeriodicalId":375277,"journal":{"name":"2011 9th IEEE/ACS International Conference on Computer Systems and Applications (AICCSA)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125002980","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}

Traditional switching mechanisms such as Wormhole Switching (WS) realize high performance, but prone to deadlock in the vicinity of faults. While some techniques such as adaptive routing can alleviate the problem, it cannot solve the problem by itself. This has motivated the development of different switching techniques. The Scouting Switching (SS) has been suggested as an efficient switching mechanism for reconciling the confliction demands on communication performance and fault-tolerance in interconnection networks. Although SS has been around for years and it can greatly benefit from adaptive routing as it reduces blocking in the network, there has been hardly any attempt to provide an analytical model for SS when fully adaptive routing along with virtual channels is used. Besides, mesh is one of the most desirable topologies regarding to characteristics which can offer very good scalability. In an effort to fill this gap, this paper proposes the first analytical model for 2-D mesh networks using SS augmented with virtual channels. Experimental results show that this model is able to predict message latency with a good degree of accuracy.","PeriodicalId":375277,"journal":{"name":"2011 9th IEEE/ACS International Conference on Computer Systems and Applications (AICCSA)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129612377","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}
