To improve the regional coverage rate and network lifetime of heterogeneous wireless sensor networks, a sensor node scheduling algorithm for heterogeneous wireless sensor networks is proposed.In sensor node scheduling Downstems algorithm, heterogeneous perception radius of sensor node is considered.Incomplete coverage constraint and arc coverage in
