Wireless Sensor Networks (WSNs) is the most promising technology to enable applications such as intrusion detection, target location and environment monitoring. In these applications, full coverage is highly required in a region of interest (ROI). Sensor nodes usually depend upon a battery for their energy source and in most deployments battery replacement is not feasible. Energy efficient sensing therefore attracts significant attention. Existing work has focused on full coverage problem under the probabilistic sensing model and which uses ?-FCO algorithm to fully ensure ?-full area coverage. For the sensor network to operate successfully, the active nodes must maintain both sensing coverage and network connectivity. Proposed work tackles such a challenging problem. It adopts probabilistic area coverage with connectivity and thereby maximizing the network lifetime. ACO algorithm is used in proposed work to solve this complex area coverage problem.
