Abstract :
In this paper, we propose an adaptive multi-hop communication protocol based on transmission power control and error correction coding to achieve energy efficiency in wireless ad-hoc network. This study is important in extending battery lifetime and consequently the lifetime of nodes and the network. We consider multi-hop communication between pair of nodes where packet needs to be re-transmitted when transmission error or packet loss occurs. Based on the quality of the communication channel (bit error rate and bandwidth) and characteristics of the packet to be transmitted, we adaptively choose the most energy efficient transmission power level and error correction coding. Simulation shows that the proposed algorithm can save significant amount of energy, reduce packet loss rate and potentially the end-to-end packet delay.
