Balanced and Centralized Distributed Energy Efficient Clustering for heterogeneous wireless sensor networks

摘要

The deployment of wireless sensor networks in many application areas requires self organization of the network nodes into clusters. The clustering Algorithm is a kind of key technique used to reduce energy consumption. Efficient way to enhance the lifetime of the system is to partition the network into distinct clusters with a high energy node as cluster head. The different methods of node clustering techniques have appeared in the literature. In this article we propose a new protocol called Balanced and Centralized Distributed Energy Efficient Clustering scheme for heterogeneous wireless sensor networks (BCDEEC), which the Base Station ensure that the high energy nodes becoming a gateways and cluster heads to improve network lifetime and average energy savings. Once the cluster heads and associated clusters are created, cluster-head-to-gateway routing is used to transfer the data to the base station to reduce the energy consumption of cluster head and decrease probability of failure nodes. Finally, the simulation results show that BCDEEC is more energy efficient and is more effective in prolonging the network life time and prolong the time interval before the death of the first node than current important clustering protocols in heterogeneous environments.
