Multi-Channel Primary Initialization Algorithm for Wireless Sensor Networks

The most urgent and important thing for a newly deployed sensor as to quickly establish a primary structure. In this paper, a practical algorithm for selecting cluster leader nodes and for setting up the affiliation of leader nodes and slave nodes is presented. Since the occurrence of collision (or co-channel interference) is a serious problem in unstructured networks, three independent channels are taken to reduce interference, Further, we analyze the algorithm based on a co-channel interference model. The simulation results show even in this harsh model, the primary initialization algorithm in our paper can be completed efficiently.
