Improved Clustering Algorithm Based on Randomization Coupled with G.A. Process
WSN (Wireless Sensor Network) uses many protocols for the communication among the sensor nodes. Initially LEACH (Low Energy Adaptive Clustering Hierarchy) removes the restrictions on the energy efficiency for the wireless sensor networks by providing the hierarchical approach for the communication between nodes and the base station and the mechanism for the election of the cluster heads which are responsible for the communication to base station. SEP (Stable Election Protocol) is one of energy efficient protocol among these protocols which are developed as an improvement over LEACH. SEP changes the environment to the heterogeneous environment and introduces the concept of advance nodes the stability and the life time of the network are the main issues focused in the previous developments.
