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.
