Abstract

For only one node assisting the cluster head node to send information in wireless sensor network cooperative transmission, an opportunity cooperative MIMO transmission scheme is proposed based on gradient algorithm. The results of analysis and simulation show that the cooperative transmission schemes based on one- bit feedback can obtain high energy-efficiency while the opportunity cooperative MIMO transmission can obtain higher energy-efficient than it. Then we propose a cooperative MIMO scheme based on cooperative node updating to improve the energy efficiency of cooperative transmission when some nodes can cooperate with cluster head node on transmission. We analyze the total energy consumption of cooperative transmission and the proportion of energy consumption of each node. The results of analysis and simulation show that the proposed scheme can effectively reduce the total energy consumption and balance the energy consumption.
