Contention-based geographic relay selection for cooperative networks has been proposed as a state-free distributed scheme to efficiently select the best relay within a geographic area. The a priori choices for the relaying area cause different effects on the overall network performance. In this paper, we focus on the fundamental problem of predefining the relaying area and investigate its impact on...
In this paper, we propose a novel relay selection scheme based on geographical information, aiming to minimize the symbol error probability (SEP) for wireless ad hoc relay networks. The proposed scheme utilizes only the source-relay and relay-destination distances as selection criteria to choose the best relay. In particular, such geographical information is often available during network initialization...
