Abstract:  

Wireless Sensor Networks WSNs have recently witnessed many improvements in Clustering and routing protocol, whereas Clustering protocols provide dynamic method for saving energy consumption. Energy considerations pose one of the most critical constraints in WSN that increase the network lifetime. Low Energy Adaptive Clustering Hierarchy protocol (LEACH) is being proposed for Energy conservation in WSN and offers one of the most common clustering-based protocols aiming to reduce the energy consumption. However, LEACH protocol suffers from the bottleneck problem experienced by cluster head absence which is lead to unbalanced and uncontrollable clusters in the network. In this paper we introduced a Four-Vice Cluster Head algorithm in LEACH protocol called F-VCH LEACH protocol that elects four Vice Cluster Heads with the cluster head in each cluster aiming to prolong the cluster lifetime in the entire network. F-VCH algorithm has been implemented and evaluated using OMNET++ simulator. Comparative analysis and results extraction was performed with the traditional LEACH protocol. Simulation results proved that F-VCH LEACH protocol has high performance in energy saving for the network
