Popis: Multiple Input Multiple Output (MIMO) is a well-established technique for increasing the link throughput, extending the transmission range, and/or reducing energy consumption. However, in the context of wireless sensor networks (WSNs), it might not be possible to install more than one antenna on the wireless terminal because of its limited space and power processing. However, wireless sensor nodes can cooperate in transmission and reception in order to deploy a virtual MIMO transmission. To address this issue, we proposed a novel energy-efficient clustering and power management schemes for virtual MIMO operation in a multi-hops WSN. We have considered both the SNR of different links and the residual energy of sensor nodes. Simulation results in terms of the average energy consumption and the network lifetime show clearly the outperformance of the proposed algorithm versus the non cooperative strategy.
