摘要:	Collision avoidance multiple access plays a significant role in Wireless Sensor Networks as there may have a huge number of nodes in a network. Therefore, it has big chance to conflict when they want to send a packet to the server at the same time. In our work, we focus on the sensor networks composed of simple function nodes and presented performance analysis of the proposed collision avoidance protocol, with emphasis on the contention process exercising in each contention subframe. We have two proposed contention scheme and we derive the probability distribution of successful minislot for each scheme and examine the efficiency of the system Our simulation results indicate that by applying second scheme, it will give a better communication efficiency rather than when we use first scheme. Keywords: collision avoidance protocol, wireless sensor networks, contention process, efficiency.
