In the stream of WSN, covering the targets using sensors and communication among the sensors to forward the data packets is a prime challenge due to the sparse target locations. Dedicated sensors lead more installation cost and significant amount of maintenance needs to be charged. Coverage of multiple targets by few sensors leads to network failure in case if any sensor runs out of power. Targets in sparse region also should be considered into account while sensing the environment. Hence in this paper, an effective multi-objective connected coverage target based WSN algorithm is proposed namely Multi-Objective Binary Cuckoo Search algorithm. The proposed model also handles the critical targets in the given sensing region. The algorithms hold the potentiality to handle minimized sensor deployment, maximized coverage and connectivity cost simultaneously. The proposed model is compared with the …
