According to characteristics of uneven energy consumption in wireless sensor networks（ WSNs）

an energy consumption balanced routing algorithm based on cooperative MIMO technology is proposed. The algorithm under the premise of ensures the domain head nodes are evenly distributed in WSNs

the whole network is evenly divided into domains. Secondly

according to the preset signal-to-noise ratio threshold range

determine optional collection of cooperative nodes

and consider remained energy

channel information

and the distance from domain head nodes of optional nodes

optimal cooperative nodes of domain head nodes will be selected out. Experimental results indicate that compared with other algorithms

this algorithm has a great improvement in network survival time

energy utilization efficiency

and balancing network energy consumption.
