Multi-channel random multi-access system in wireless sensor networkwith probability detection and nonpersistent CSMA

This paper presented a new wireless sensor network protocol named probability detection and nonpersistent CSMA in multi-channel random multi-access (PDNMMA).By dividing transmission time of packet into 1+ a,the throughputs and packet delay were presented through theoretical calculations. Through adjusting the probability the p value,controlling the number of nodes in carrier sense multiple access and sleep sites,it effectively reduced the system energy consumption,and extended the nodes of the life cycle.We proved that theoretical analysis was true through computer simulation experiment.
