Research on Opportunistic Cooperation Transmission and Its Performance in Wireless Sensor Network

摘要

摘要: 该文基于Nakagami信道且考虑节点电路处理能耗，研究无线传感器网络中机会协作传输及其性能，解决怎么协作何时协作协作的性能3个问题，并从理论上分析机会协作的可能性。仿真结果表明：机会协作传输能有效地提高系统性能；节点的电路处理能耗会影响系统性能，当节点电路处理能耗大到一定程度，机会协作传输不能带来任何性能增益。

Abstract: Scheme of opportunistic cooperation transmission and its performance in wireless sensor network is studied based on Nakagami channel in this paper, and effect of circuit power on the scheme is also researched. Three issues including how to cooperation, when to cooperation and performance of cooperation are solved. And probability of opportunistic cooperation is discussed from theory. Simulation results show that opportunistic cooperation transmission can reach better performance than direct transmission, and circuit power of sensor node also has great effect on system performance.
