Energy-efficient cooperative communication in wireless sensor networks using turbo codes

Abstract

Energy efficiency is the main issue in the wireless sensor network. In this paper, we have developed the energy model for Virtual-Multiple Input Single Output cooperative communication using turbo codes. We have compared the energy consumption of uncoded cooperative communication with coded cooperative communication. The effect of code rate, number of participating nodes, channel conditions, target bit error rate on the energy consumption is also investigated. The simulation results show that significant energy saving can be obtained through the proposed turbo coded cooperative communication.
