Multi-hop Hierarchical Routing Based on the Node Health Status in Wireless Sensor Network

This paper proposed multi-hop hierarchical routing to monitor forest fire using wireless sensor network. The node health status is introduced in choosing Cluster Head (CH) in order to avoid route breakages caused by CH that burns off. CHs transmit their data to the closest CH which is in the direction to the Base Station. The performance of the proposed method is compared to the Leach, MTE, and the direct algorithm. The extensive simulation is done by NS2 with results showing that the proposed method outperforms others in term of the number of packets received, energy consumed, the number of nodes alive, and average end to end delay.
