Currently, almost all manufactured MTs uses HDLC_PPP to make connections between TE and MT. However HDLC_PPP uses byte stuffing for HDLC framing. As the communication speed is increased dramatically between TE and MT, byte stuffing seriously limits communication speed. As the connection methods between TE and MT and between MT and RN Care different, HDLC_PPP used between TE and MT can be replaced by other method without affecting the wireless interface. We propose an Ethernet interface instead of HDLC_PPP interface. The Ethernet-based interface provides higher data throughput than that of HDLC_PPP. The test result shows that data throughputs of HDLC_PPP over USB, pure Ethernet, and Ethernet over USB are 18Mbps,95Mbps, and 68Mbps respectively.","PeriodicalId":115389,"journal":{"name":"2009 Second International Conference on Advances in Mesh Networks","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134249742","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, such opportunistic scheduling algorithm can be challenged in a system where each secondary user belongs to a different independent agent and the users work in competitive way. In order to optimize his own utility, a selfish user can choose not to reveal his true information to the central scheduler. In this paper, we proposed a pricing mechanism which combines the mechanism design with the opportunistic scheduling algorithm and ensures that each rational selfish user maximizes his own utility function, at the same time optimizing the overall system utility. The proposed pricing mechanism is based on the classic Vickrey-Clark-Groves (VCG) mechanism and had several desirable economic properties. A mechanism learning algorithm is then provided for users to learn the mechanism and to obtain the Nash equilibrium. A numerical example shows the Nash equilibrium of such algorithm achieves system optimality.","PeriodicalId":115389,"journal":{"name":"2009 Second International Conference on Advances in Mesh Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133343916","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 aspects of scalability and signaling cost are evaluated respectively: the scalability is evaluated by numerical analysis while the signaling cost with respect to delay is evaluated by a virtualization-based method. It is shown that the SPMIPv6 extension can scale the network better than the base Proxy Mobile IPv6 (PMIPv6) protocol.

The traditional multiuser scheduling algorithms, Max C/I algorithm for system throughput maximization and proportional fairness (PF) algorithm for user fairness, are extended into the DF cooperative relay systems. The simulation results show that the Max C/I algorithm obtains great multiuser diversity gain and cooperation diversity gain. In the Max C/I algorithm, deploying more RSs in the cell has a constructive effect on the multiuser diversity. However in PF algorithm, adding more RSs in the cell has an adverse effect on the multiuser diversity. Varying number of users has big impact on the user fairness performance of Max C/I, but the user fairness of PF is mainly affected by the RS number.","PeriodicalId":115389,"journal":{"name":"2009 Second International Conference on Advances in Mesh Networks","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131090050","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}

Current multi-channel schemes implementing a dedicated control channel lead to saturation problems. Channel selection and coordination schemes which minimize the effects of channel switching penalty and channel bottlenecks are required. The paper proposes a cyclical scheduling algorithm where data transmission is phased. A single dedicated channel with two data channels and one transceiver system is explored. The capacity of a single control channel is investigated as the number of data channels is increased from two to fourteen. Channel saturation is observed on data channels. Analytical results show that a single dedicated control channel causes no bottlenecks up to a fourteen data channels system. Its capacity is affected by the saturation of data channels.","PeriodicalId":115389,"journal":{"name":"2009 Second International Conference on Advances in Mesh Networks","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126893573","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}
