In the era of New Generation Networks (NWGN) many emerging and future enable technologies accomplish the requirements of ubiquitous communication networks. Wireless Sensor Networks (WSNs) is a vital category of these stateof-the-art technologies, the enormous concerns of these networks are energy efficient and well-organized data aggregation. Cluster based routing in WSNs is an immense solution to enhance the energy efficiency of the nodes and resourceful data gathering. Many studies on network

The lifetime of WSNs will be affected by the cluster head (CH) selection; this is because a CH consumes more power than a regular (non-CH) node. In this research study, an energy efficient cluster head selection in Mobile Wireless Sensor Networks is proposed, analysed and validated on the basis of residual energy and randomized selection of the node, who is not assigned as a cluster head in previous round. Moreover, the proposed approach shows the significant improvements when compared with LEACH and A Novel Application Specific Network Protocol for Wireless Sensor Networks (Hybrid Multi-hop LEACH) protocols in terms of energy consumption of sensor nodes, enhanced network lifetime and efficient data gathering due to less energy consumption during data transmission.
