An Energy-Efficient Chain-Based Routing Protocol in Wireless Sensor Network

摘要：

Nodes in Wireless Sensor Network (WSN) are energy-constrained and have limited bandwidth. PEGASIS (Power-Efficient Gathering in Sensor Information Systems) presented in 1 is an excellent solution on energy efficiency where each node communicates only with a close neighbor and takes turns transmitting to the BS (Base Station). In this paper, we propose EECB (Energy-Efficient Chain-Based routing protocol) that is an improvement over PEGASIS. EECB uses distances between nodes and the BS and remaining energy levels of nodes to decide which node will be the leader that takes charge of transmitting data to the BS. Also, EECB adopts distance threshold to avoid formation of LL (Long Link) on the chain. Our analysis and simulation results show that EECB outperforms PEGASIS in the lifetime of WSN.
