Relay Selection and Power Allocation Scheme for Cellular Network Using Cooperative Diversity

In this paper,a novel network architecture that incorporating cooperative diversity techniques to increase the cellular network throughput is proposed.We design a relay selection strategy in this network architecture design,where the proxy node will select a relay node based on the channel quality and nodes'residual energy to enhance the users'fairness among the nodes. Moreover,we propose a novel power allocation scheme to minimize the power consumption of the whole network.The implementation of the algorithm is given to show that the proposed relay selection and power allocation scheme can provide significant network performance improvement in terms of network power consumption and quality of service due to the using of cooperative diversity techniques.
