Application-prioritized hierarchical routing protocol for wireless sensor networks

Abstract

A novel approach on application prioritization for Wireless Sensor Network (WSN) is proposed in this paper. This approach attempts to modify the existing node structure in the WSN by adding multiple applications on a node and prioritizing them based on available energy criterion to achieve the network performance. For evaluation of the proposed approach three existing hierarchical WSN protocols Low-Energy Adaptive Clustering Hierarchy (LEACH), Distributed Energy Efficient (DEEC) and Threshold Distributed Energy-Efficient Clustering (TDEEC) are modified and performance is analyzed considering five different cases. The modified TDEEC with prioritization approach has shown notable performance improvement in terms of throughput, network stability and network lifetime compared to other protocols considered for the evaluation study.
