摘要：Wireless Sensor Networks (WSNs) are experiencing a revival of interest and a continuousadvancement in various scientific and industrial fields. WSNs offer favorable low cost andreadily deployable solutions to perform the monitoring, target tracking, and recognition ofphysical events. The foremost step required for these types of ad-hoc networks is to deploy allthe sensor nodes in their positions carefully to form an efficient network. Such network shouldsatisfy the quality of service (QoS) requirements in order to achieve high performance levels. Inthis paper we address the coverage requirement and its relation with WSN nodes placementproblems. In fact, we present a new optimization approach based on the Flower PollinationAlgorithm (FPA) to find the best placement topologies in terms of coverage maximization. Wehave compared the performance of the resulting algorithm, called FPACO, with the originalpractical swarm optimization (PSO) and the genetic algorithm (GA). In all the test instances,FPACO performs better than all other algorithms.
