An Energy Efficient Hybrid Code Combining Technique for Cooperative Wireless Networks
In this paper, an energy efficient hybrid code combining technique is proposed for a cluster based cooperative wireless networks. The authors' scheme uses hybrid of selective repeat ARQ and Low Density Parity Check (LDPC) for code combining techniques. In the existing cluster based code combining techniques, energy consumption is more in the cluster heads and hence the energy level of the cluster head is drained before the data reaches the destination. In order to overcome this, a clustering technique is proposed in which the selection of cluster heads is based on the connectivity and the residual energy of each node. The clustering architecture consists of source cluster, destination cluster and relay clusters.
