This paper focuses on a new in-operation self-testing mechanism. This mechanism is used to detect the silicon defects of cores of SoC chips in working state. It makes embedded cores to automatically check their failures by themselves based on IEEE std I500TM and Core Test Language. According to Experiments, as a compromise, this In-operation Self-Test mechanism slows down the computation performance of SoC chips. Using this mechanism ensures finding exception in time and in turn adopting spare scheme in time, as well as it outperforms previous approaches in reducing cost of importing failure tolerance mechanisms into SoC chips.","PeriodicalId":367703,"journal":{"name":"2007 International Conference on Parallel Processing Workshops (ICPPW 2007)","volume":"160 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116212515","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}

One of the most frequently used spatial queries is the reverse nearest neighbor (RNN) query that returns the objects whose nearest neighbor is the query object. RNN answers are particularly essential to the users who are under emergency circumstances. In this paper, we propose an incremental RNN search (IRS) method to answer RNN queries for moving objects in sensor networks. IRS employs a filter- verification framework to achieve the energy-efficient query processing by filtering out most objects irrelevant to the query results. To support the execution of IRS, we also design a distributed object location management scheme to reduce the amount of communication in managing moving objects. Our experimental results reveal that IRS is indeed quite promising, as it requires only a moderate amount of communications for managing moving objects as well as for processing RNN queries.","PeriodicalId":367703,"journal":{"name":"2007 International Conference on Parallel Processing Workshops (ICPPW 2007)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126794855","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}

However, its applications in multicast routing remain largely unexplored. In this paper, we propose the DCGM (destination clustering geographic multicast) routing protocol for wireless sensor networks. By clustering destinations that can share the same next hop, we iteratively select the next hop as the neighbor with the maximum number of destinations. We prove that the complexity of DCGM is O(nk), where n is the number of neighbors of the current node and k is the number of destinations associated with the current node. Simulations show that DCGM achieves better performance than existing geographic multicast algorithms in terms of path length, but with much lower computation complexity.","PeriodicalId":367703,"journal":{"name":"2007 International Conference on Parallel Processing Workshops (ICPPW 2007)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131463208","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}

By means of simulations, we analyze the performance of three protocols: AODV, DSR, and DSDV considering two radio models Two Ray Ground and Shadowing. In difference with other works, we generalize the type of radio model by allowing the path-loss randomnesses to be present in the service environment of the network. We study the perceived good put at the sink node and compare the performance of three protocols for different scenarios. The simulation results confirm the fact that the shadowing phenomena, by destroying the regularity of the network, reduce the mean distance among nodes and at the same time increase the interference level and the latency of packet transmission. We found that the packet delivery ratio of AODV and DSR routing protocols are more stable than DSDV protocol.","PeriodicalId":367703,"journal":{"name":"2007 International Conference on Parallel Processing Workshops (ICPPW 2007)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131904234","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}

While using multiple radios improves network throughput, it undermines TCP's underlying assumptions. When deployed in wireless mesh networks, TCP faces four challenges: transmission errors, packet reordering due to multipath routing, multihop connections and congestion. If not handled properly, they can incorrectly trigger TCP congestion control mechanisms and cause poor performance. In this paper, we propose a new TCP enhancement, named Congestion Coherence, to address these challenges. Simulation results confirm that this enhancement significantly improves TCP performance in wireless mesh networks.","PeriodicalId":367703,"journal":{"name":"2007 International Conference on Parallel Processing Workshops (ICPPW 2007)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124924241","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 employ computational economy as a way to manage and allocate these distributed resources. It can help to rapidly and dynamically select resources meeting users' functional requirements and satisfying their Quality of Service (QoS), from a large number of resources. An economic scheduling system based on market model is presented. On the basis of studying QoS criteria of resource services, we formulate selection as Multiple Attribute Decision Making (MADM) problem. Then, we introduce MQoS model to evaluate resource services for selection, which consists of the MQoS vector, a decision matrix and a quality- driven scheduling algorithm. The algorithm is classified as lexicographic and Euclidean Distance algorithm with respect to user's preference and object impact. It optimizes system performance through adjusting resource selection automatically according to previous job execution and the current system state information such as load. The results of scheduling experiments showed the superiority of quality-driven algorithm in scheduling on global grids.","PeriodicalId":367703,"journal":{"name":"2007 International Conference on Parallel Processing Workshops (ICPPW 2007)","volume":"331 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115972323","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}
