Selective-relay cooperative systems have been proposed to save energy as well as improving bandwidth efficiency and reducing time delay in wireless systems. In this paper, energy consumption of two proposed Timer-based selection methods, opportunistic relay (OR) and selective cooperation (SC), are investigated for a decode and forward (DF) relay network. We consider the best modulation strategy, uncoded...
This paper investigates an optimization of the conventional relay selection for multirelay environments. In contrast with previously reported selection schemes, where a selected relay accesses the channel in a dedicated cooperative slot, the proposed scheme recovers the bandwidth loss of the half-duplex constraint by allowing two relays to simultaneously access the channels. Based on an appropriate...
