  • Abstract In the wireless sensor network environment (WSN), the system transmits signals often need to rely on the stability and reliability of the relay node of each path of cooperation with each other to achieve balance between leisure and stability. In general, relay adopted Amplify-and-Forward (AF) and Decode-and-Forward (DF) to relaying the signal to destination. Unfortunately, in reality, the relay node itself had a problem of limited energy supplies, would make the overall performance degrade before reaching the optimal performance.
    Therefore, we propose two novel relay selection schemes and through the multi-hop transmission with cooperation. We also derived the optimal power allocation algorithms for all relay nodes. Finally, simulation results show that our proposed scheme obtained the better lifetime and performance where compared with the traditional schemes in a fair environment.
