In order to speed up the path searching and cut the energy consumption,a new BWAS(best-worst ant system)-based dynamic clustering routing algorithm for WSN are presented in this paper.This algorithm uses BWAS-based method to find the optimal multi-hop path from the cluster-head nodes to the sink node while the dynamic clustering models are used for energy management in WSN.It transmits the data to the sink node in the way of the multi-hop relay.The BWAS algorithm improves the ant colony algorithm by evaluat...
