Improving Quality of Service Through Enhanced Node Selection Technique in Wireless Sensor Networks

Abstract

Wireless sensor networks (WSNs) consist of frivolous devices with low cost, low power and short-ranged wireless communication. The sensors in the network can communicate with each other to form a network. In this paper, we propose the Enhanced Node Selection Technique (ENST) approach for vigorous multipath QoS routing for WSNs. This approach is based on determining the optimized node that helps route discovery for improving the QoS parameters in the communication network. The selection of enhanced nodes makes the chain for route selection using received signal strength indicator (RSSI) and residual energy. Simulation analysis shows that ENST improves throughput, end-to-end delay, packet delivery rate and extend the energy efficiency of the communication network.
