A study on SEP towards energy efficient wireless sensor networks

In a sensor network, the energy is consumed rapidly by the sensor nodes, and drains battery power quickly. Hence, resulting in short lifetime of the nodes around the sink because of high amount of traffic in the system, mentioned as bottleneck zone. The work studies to opt for a single-hop as nodes which are present in the bottleneck zone, acting as cluster head, communicating with base station. Based on different literature, the issues still lies with the proper implementation of heterogeneous sensor networks and thus, an overview perspective has been shown towards the constraints and some possible solutions in terms of energy efficient network.
