Optimization Localization in Wireless Sensor Network Based on Multi-Objective Firefly Algorithm

Specifying the located nodes of a network plays an important role in the success of many wireless sensor network (WSN) applications including object tracking, detecting, monitoring, etc. In this paper, the multi-objective firefly algorithm for estimating the located nodes in a network is proposed to solve the localization issues in WSNs. Objective functions of estimating the locations of all the nodes of WSN are considered based on two criteria including the distance of nodes, and the geometric topology constraint. The simulation results are compared with other methods in the literature show that the proposed method produces the considerable improvement in terms of localization accuracy and convergence rate.
