Summary:
Wireless Sensor Networks (WSNs) have attracted a significant amount of interest from many researchers for a wide range of applications, such as natural environmental monitoring and environmental control in residential spaces or factories. To realize long-term operation of WSNs, we discuss in this study a method of suppressing the communication load on sensor nodes by effectively placing a limited number of sink nodes in an observation area that integrate sensing data from nodes around them. As a technique of solving effective locations for sink nodes, this paper proposes a method using a simple competitive PSO for finding plural acceptable solutions. The simulation results show that obtained solutions can contribute to prolonging lifetime of WSNs.
