TRANSFORMING AREA COVERAGE TO TARGET COVERAGE TO MAINTAIN COVERAGE AND CONNECTIVITY FOR WIRELESS SENSOR NETWORKS

Area coverage is one of the key issues for wireless sensor networks.It aims at selecting a minimum number of sensor nodes to cover the whole sensing region and maximizing the lifetime of the network.In this paper, we discuss the energy-efficient area coverage problem considering boundary effects in a new perspective, that is, transforming the area

In islanding, a portion of the power network, comprised of the loads and distributed generation (DG) units, is isolated from the rest of the power grid and forms a micro grid (MG).In this condition, it becomes essential for the islanded MG to operate in a stable and controlled manner by providing ancillary services.When the MG is cut off from the m
