This often leads to sub-optimal results in enterprise WLAN with a large number of users. Therefore, network operators expects the ability to dominate AP association selection and AP handoff initiation so that better AP/client association can be achieved. In addition, AP handoff procedure involves time-consuming packets exchange. Although many methods have been proposed to simplify AP handoff procedures, there is at least hundreds of milliseconds during which client's data transmission is blocked. In this paper, we proposed the abstraction of “One Big AP” in which unmodified 802.11-compliant client is tricked into believing that there is one access point with very large coverage, while the AP that sends and receives its packets has changed. To support the“One Big AP” illusion, we leveraged the emerging idea of Software-Defined Networking (SDN) to reform the architecture of enterprise WLAN. In the SDN-based architecture, we can easily realize network-controlled AP association and client-transparent AP handoff. We demonstrated the feasibility and efficiency of our solution through simulation.","PeriodicalId":412971,"journal":{"name":"2014 Sixth International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123693152","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}

Because of the integer nature of channel, most of the current reservation schemes were based on integer. However, the number of reserved channels of integer reservation schemes can't be adequately adjusted as a result of optimizing the system performance. In this paper, we model the cognitive radio network as a two-dimensional Markov process, which overcomes the restriction of integer nature of channel. Then two fractional reservation schemes are realized. One is fractional channel reservation for primary user (FCRPU), the other is fractional channel reservation for handoff secondary user (FCRHSU), both of which can solve the trade-off problem above very well. The precision of analytical results is validated by Monte Carlo Simulations, on the strength of which we come to the conclusion that fractional channel reservation scheme and the FCRHSU scheme can achieve better performances than the integer one and the FCRPU one, respectively.","PeriodicalId":412971,"journal":{"name":"2014 Sixth International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125012175","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, it is challenging to provide satisfactory performance in such systems, due to the sporadic energy arrival and the low harvesting rate. In this paper, we propose a novel cooperation strategy for EH networks with the help of multiple EH relays, each of a steady but low harvesting rate. Different relays will take turns to assist the source-destination transmission, and thus energy diversity can be achieved. To provide steady communications, we formulate the design problem as to maximize the minimum utility during the considered transmission duration, which, however, is NP-hard. We propose a general framework to develop efficient suboptimal algorithms, which consists of 1) a sufficient condition for the feasibility of the optimization problem and 2) an efficient bisection algorithm to find a suboptimal solution. Simulation results will show that the proposed cooperation strategy can provide significant power gains over the direct link transmission, and the proposed suboptimal algorithm can provide near-optimal performance. Compared to the best-effort cooperation that only optimizes the current transmission block, the proposed strategy can achieve the same performance with much fewer relays.","PeriodicalId":412971,"journal":{"name":"2014 Sixth International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122101604","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}

Based on the traffic load, neighboring base stations (BSs) cooperate to optimize the BS switching (sleeping) strategies so as to maximize the energy saving while guaranteeing users' minimal service requirements. An interaction graph is defined to capture the network impact of the BS switching operation. Then, we formulate the problem of energy saving as a constrained graphic game, where each BS acts as a game player with the constraint of traffic load. The constrained graphic game is proved to be an exact constrained potential game. Furthermore, we prove the existence of a generalized Nash equilibrium (GNE), and the best GNE coincides with the optimal solution of total energy consumption minimization. Accordingly, we design a decentralized iterative algorithm to find the best GNE (i.e., the global optimum), where only local information exchange among the neighboring BSs is needed. Simulation results finally illustrate the convergence and optimality of the proposed algorithm.","PeriodicalId":412971,"journal":{"name":"2014 Sixth International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123515894","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}
