Multi-hop hierarchical routing based on the node health status in wireless sensor network

© Springer Nature Switzerland AG 2019. 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

Distance-Based and Low Energy Adaptive Clustering Protocol for Wireless Sensor Networks

A wireless sensor network (WSN) comprises small sensor nodes with limited energy capabilities. The power constraints of WSNs necessitate efficient energy utilization to extend the overall network lifetime of these networks. We propose a distance-based and low-energy adaptive clustering (DISCPLN) protocol to streamline the green issue of efficient energy utilization in WSNs. We also enhance our proposed protocol into the multi-hop-DISCPLN protocol to increase the lifetime of the network in terms of high throughput with minimum delay time and packet loss. We also propose the mobile-DISCPLN protocol to maintain the stability of the network. The modelling and comparison of these protocols with their corresponding benchmarks exhibit promising results
