Energy-Efficient Routing Protocol for Coverage and Connectivity in WSN

Wireless Sensor Network (WSN) has varying applications in environmental monitoring, industrial monitoring, military, and other fields, which gain much attention towards it. With these applications there different issues arise, such as coverage connectivity and energy consumption. Coverage connectivity and energy efficiency have a fundamental concept in developing and designing a Wireless Sensor Network. The proposed protocol focused on coverage and energy consumption issues in the sensor network. A model is considered for the three-level heterogeneous network where residual node energy and Base Station distance is considered as a parameter for CH selection, and overlap of nodes during coverage is also considered. The coverage problem in the network is minimized by estimating the number of active nodes needed to cover the sensing area.
