Design and Implementation of EOICHD Based Clustered Routing Protocol Variants for Wireless Sensor Networks

Efficient energy utilization and network life prolongation are primary objectives to be considered when designing a Wireless Sensor Network. Cluster-based routing protocols most suitable for achieving such goals. Energy Optimal Inter Cluster Head Distance (EOICHD) is cluster-based hierarchical protocol inspired by the Low-Energy Adaptive Clustering Hierarchy (LEACH) protocol. EOICHD resolves problems associated with LEACH protocol, as selecting cluster head nodes in close proximity. By carefully based on residual optimal inter-cluster distance, ensures that selected separated certain distance. This approach uniform distribution of across entire network. The study presented so far not sufficient. Hence, this paper, we propose three variants understand its behavior better manner. A comparative analysis all variants, LEACH-central constrained (LEACH-C) performed considering parameters alive nodes, cumulative energy, data packets arrived at base station, stability
