A Relay Selection Cooperative MIMO Communication Scheme for Network Lifetime Maximization

In this paper, we propose a relay selection scheme based on cooperative MIMO (multi-input-multi-output) communication for network lifetime maximization in energy-constrained sensor networks. Compared with existing work, our distributions are: cooperative nodes choice is not based on minimizing energy consumption per communication but balancing remaining energy between participants including source and cooperators based on one special application. We validate the efficiency of the proposed algorithm by simulation by comparing it with the direct communication and minimizing energy consumption communication schemes.
