These networks can be employed to enable forces to extend the remaining circuit- switched communication infrastructure. This paper introduces a system architecture, a self-organized topology construction and channel allocation algorithm and its implementation in a distributed protocol. The architecture relies on commercially available IEEE 802.16-2004 (WiMAX) equipment that can be employed to build routers and gateways to a wired network. The topology construction and maintenance are based on a modified Dijkstra shortest path algorithm that maximizes a combined metric of path qualities and gateway load. Path qualities are derived from link qualities determined by SINR measurements. The channel allocation greedily allocates the locally least-interfered channel. The protocol includes four sub- protocols: a join protocol, a hello protocol, a leave protocol, and a conflict resolution protocol to resolve inconsistencies in topology data across the network. The proposed architecture, algorithms, and protocol have been assessed via extensive simulations and implemented on hardware. Both, simulation results and field tests confirm their applicability/usability.","PeriodicalId":271067,"journal":{"name":"2009 IEEE International Conference on Communications Workshops","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129478463","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 primary user transmits with a constant power and utilizes an adaptive modulation and coding (AMC) scheme satisfying a bit error rate requirement. We propose a link adaptation scheme to maximize the average spectral efficiency of the cognitive radio, while a minimum required spectral efficiency for the primary user is provisioned. The resulting problem is constrained to also satisfy a bit error rate requirement and a power constraint for the cognitive link. The AMC mode selection and power control at the cognitive transmitter is optimized based on the scaled signal to noise plus interference ratio feedback of both links. The problem is then cast as a nonlinear discrete optimization problem for which a fast and efficient suboptimum solution is presented. We also present a scheme with rate adaption and a constant power. An important characteristic of the proposed schemes is that no negotiation between the users is required. Comparisons with underlay and interweave approaches to cognitive radio with adaptive transmission demonstrate the efficiency of the proposed solutions.","PeriodicalId":271067,"journal":{"name":"2009 IEEE International Conference on Communications Workshops","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130063027","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}
