Due to stringent accessing and interference constraints, secondary users appeal to exploit multi-path routing based on multi-hop relaying protocol to support QoS requirements. Via our model, we derive the end-to-end delay statistics including medium access and retransmission delay, where we successfully relate path diversity to end-to-end reliability and optimize the delivery delay by adjusting transmission power. We analyze the performance of the duplication-based and coding-aided multi-path routing schemes, where opportunistic transmission is employed to improve the delivery delay due to channel awareness, and encoding packets on multiple paths further achieves throughput efficiency. This paper firstly presents insights and performance analysis to facilitate multi-path routing with QoS provisioning in underlay CRN.","PeriodicalId":402219,"journal":{"name":"2011 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126131382","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}

Compared with most of the existing sensing schemes which simply use listen-before talk (LBT) only at the transmitter side, the proposed scheme can further improve the system performance by jointly feedback the Channel State Information (CSI) and the Sensing information (SI) from the receiver. However, the quantization impact on the sensing performance and the channel capacity as well as the interference to primary network should be considered in the case of limited feedback. Here a tradeoff criterion is proposed to allocate bits for CSI and SI so as to maximize the MIMO link capacity while meeting the interference constraints. Simulation results are given to verify the effectiveness of the proposed scheme.","PeriodicalId":402219,"journal":{"name":"2011 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125879886","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}

An intelligent wakening scheme (IWS) is proposed in this paper which considers different importance degrees of the grids in the surveillance zone. It uses a voronoi diagram to determine the effective scope of each sensor node and calculates the node wakening probability with the importance degree in the effective scope. The nodes are then turned on stochastically according to the node wakening probability. Simulation results illustrate that this scheme greatly reduces the number of wakening nodes while maintaining high reliability in surveillance.","PeriodicalId":402219,"journal":{"name":"2011 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129401322","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 propose an analytical model to accurately represent the impact of green network technologies (i.e., low power idle and adaptive rate) on network- and energy-aware performance indexes. The model has been validated with experimental results, performed by using energy-aware software routers and real-world traffic traces. The achieved results demonstrate how the proposed model can effectively represent energy- and network-aware performance indexes. Moreover, also an optimization procedure based on the model has been proposed and experimentally evaluated. The procedure aims at dynamically adapting the energy-aware device configuration to minimize energy consumption, while coping with incoming traffic volumes and meeting network performance constraints.","PeriodicalId":402219,"journal":{"name":"2011 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128073636","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}

EagleEye offloads the logging function from the distributed application program so that applications can focus on the logic handling without worrying about when and how to do logging. By capturing and analyzing network packets, EagleEye is able to reproduce the entire networking event history in the application layer, which is the basis of implementing an accountable system. We provide a case study by replacing the logging component of PeerReview [1] with EagleEye. The evaluation result shows that EagleEye can achieve equivalent accountability without modifying the host application program, which can save numerous workloads of modifying, republishing, and redeploying the host software.","PeriodicalId":402219,"journal":{"name":"2011 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130074456","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}

Contemporary WSN routing algorithm designs have severe limitations on their scalability; that is, large-scale deployments of WSNs result in relatively shorter lifetimes, as compared to small-scale deployments, primarily owing to rapid sink node isolation caused by the quick battery exhaustion of nodes that are close to the sink. In this paper, we analyze the scalability limitations of conventional routing algorithms and compare them to those of our recently proposed Hybrid Multi-hop routing (HYMN) [1]. We mathematically analyze HYMN and show the relationship between network size and routing algorithm scalability. Additionally, through extensive simulations, we show that HYMN scales considerably better in terms of network connectivity.","PeriodicalId":402219,"journal":{"name":"2011 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"4 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120988289","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 considerable amount of research on distributed hash table (DHT) based mobility support schemes, which are highly user scalable and load balanced, has been done. However these schemes have shortcomings in query and update performances and network scalability. It is because although routing of overlay itself is effective, there is inconsistency between logical and physical topologies, so the actual physical network performances are not necessarily efficient. In this article, while modeling the overlay mapping query to a Markov decision process (MDP), we define the reward function combining physical layer information with application layer information. Then we present a Markov decision routing (MDR) algorithm, which improves backward induction to get the global optimal strategy, and can balance the complexity of the time and space.We propose a DHT and MDR-based mobility management (DMDRMM) scheme. The numerical results show that the scheme inherits the advantages of the DHT-based management structure, and optimizes the update and query performances of dDHT especially for large-scale network.","PeriodicalId":402219,"journal":{"name":"2011 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125972335","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}

Recent concerns about declassification polices have provided many choices for practical intended information release, but more precise enforcement mechanism for these policies is insufficiently studied. In this paper, we propose a security property on the where-dimension of declassification and present an enforcement based on automated verification. The approach automatically transforms the abstract model with a variant of self-composition, and checks the reachability of illegal-flow state of the model after transformation. The self-composition is equipped with a store-match pattern to reduce the state space and to model the equivalence of declassified expressions in the premise of property. The evaluation shows that our approach is more precise than type-based enforcement.","PeriodicalId":402219,"journal":{"name":"2011 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125252243","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}
