Abstract:

A partners choice algorithm is proposed based on cooperative multi-input multi-output (MIMO) transmission in energy-constrained sensor networks. Compared with existing work, the distributions are that the cooperative nodes choice in every transmission is not based on minimizing energy consumption but balances residual energy between participant nodes including source node. The efficiency of the proposed algorithm by simulation is validated when comparing with the direct transmission and minimizing energy consumption transmission.
