A study of energy conserving adequate coverage protocol for maximizing the lifetime of wireless sensor network

The use of Wireless sensor network is to monitor an area for event detection. The sensor node have some limitation like the sensor node associated with battery power and generally it is not possible to recharge or replace battery of sensor due to large number of sensor node, node distribution in remote, desert or hostile areas etc. The energy consumption of sensor node appears a lot of challenges for the researchers. sensor node consume energy for doing its operation (sensing and transmitting). For saving energy and prolong the lifetime of sensor network we using some mechanism and energy efficient coverage and routing protocol. In this paper we discuss and analysis a robust energy saving protocol (PEAS) for improving the lifetime of network. We also review some preliminary of wireless sensor network.
