In this paper, we address the issue of energy tradeoff made by relay nodes between transmitting their own data and forwarding other nodes' information in fading channels. First, assuming perfect channel state information (CSI), we propose a power control policy in a two-node relay network under which total energy consumption across both nodes is minimized while meeting both outage probability requirements. However perfect CSI at each node is not possible in general due to bandwidth limitations that prevent the full exchange of precise channel information. Thus in this paper, we develop power control algorithms for relaying under bandwidth constraints, via quantization. Specifically, we develop a quantization protocol that accounts for the asymmetric nature of uplink/downlink communication bandwidths and develop an optimal polynomial time algorithm for channel quantization using this protocol. The quantization algorithm minimizes the sum of expected transmission powers at the source and relay, required for collaborative relaying to satisfy the given outage probability.","PeriodicalId":151241,"journal":{"name":"2007 41st Annual Conference on Information Sciences and Systems","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132089445","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 context, we introduce a game-theoretic max-min formulation for multiple access in the presence of the correlated jamming, replacing the mutual information game setup that has been studied so far. The novel formulation is well-suited for power-limited systems. Specifically, the AP strives to maximize the network's lifetime by minimizing sum-power while guaranteeing a minimum sum-rate for the users. We show that the AP's optimal strategy is a greedy one which allocates power to the strongest user, while the jammer's best response is to reduce the aggregate channel gain of the strongest user as much as possible. Hence, the multiuser game with a sum-rate constraint is equivalent to a single-user game where only the strongest user is present. Numerical results verify the correlated jammer's improved capability to inflict severe disruption in low data rate and low user channel gain settings. However, in a high data rate regime, generating white noise is the jammer's best strategy.","PeriodicalId":151241,"journal":{"name":"2007 41st Annual Conference on Information Sciences and Systems","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124349518","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}
