CHOP: Maximum Coverage Optimization and Resolve Hole Healing Problem using Sleep and Wake-up Technique for WSN

The Sensor Nodes (SN) play an important role in various hazardous applications environments such as military surveillance, forests, battlefield, etc. Wireless Network (WSN) comprised multiple numbers of sensor nodes which are used to perform sensing the physical conditions and subsequently transmitting data Base Station (BS). have limited batteries. random distribution areas causes overlapping coverage hole issues network. Coverage Optimization Resolve Hole Healing (CHOP) Protocol is proposed optimize network's resolve problem. working phases protocol network initialization, formation cluster, Selection Cluster Head, sleep wake-up phase. optimized, maximum achieved for a specific range. Using statistics probability theory, link established between radius node area. wake phase select optimal active achieve coverage. outperformed showed improvements performance lifetime compared LEACH, TEEN, SEP, DEEC protocols.
