Some Aspects of Coverage Awareness in Wireless Sensor Networks

Wireless sensor network (WSN) consists of network of wireless nodes that have the capability of computation, communication and sense a parameter of interest. WSN developers face challenges that arise from memory and computational constraints, link failures and limited battery power. Coverage problem significantly affects network performance, which defines how well attendants/sensors monitor an area by their sensing ability. Today, most of the researchers working towards coverage in wireless sensor networks. And the different coverage metrics are used to measure the WSN coverage performance. So, this paper provided the brief and quick understanding of the coverage issues and metrics against coverage in wireless sensor networks.
