An Energy-Efficient Routing Protocol Based Dynamic Cooperative MIMO for Wireless Sensor Network

Abstract

WSN network is energy constrained, the energy consumption of the network has stringent limited. During design routing protocols, Energy issues is important factors to be considered. Without increasing send energy of nodes, MIMO technology can make use of the cumulative energy of the sending node to increase the sending signal to noise ratio, thus reducing the error rate and improve the reliability of data communication, In the same transmit power and bit error rate situations, Using MIMO technology can provide higher data rates, reducing the node sending time, thereby reducing the forward node processing and communication cost. In this paper, Based on dynamic collaborative virtual antenna MIMO technology, a new energy efficient routing protocol is proposed. In the specific application environment, Simulation shows that the protocol has better energy efficiency.
