Title : Energy Efficient Cluster-based Cooperative Communication in M2M Capillary Network
Abstract:
Cluster-based cooperative Multiple-Input-Single-Output (CMISO) communications is a promising way to prolong network lifetime in machine-to-machine (M2M) capillary networks. The cluster-based communications can introduce excessive energy overhead to the cluster heads (CH), contributing to shorten network lifetime which is defined as the duration from the deployment of the network to the time that the battery of the first node is fully drained. CMISO transmission is considered as an effective way to release the burden of CH by selecting cooperative nodes to assist CH to transmit data. In my research, we propose an energy saving scheme by jointly CH selection and cooperative nodes selection with the objective of improving the network lifetime. The merge-and-split operation based on Pareto order method is applied. Simulation results show that proposed algorithm outperforms CMISO transmission with LEACH protocol in terms of network lifetime.
