Quality of service improved in WSNs using Improved Efficient Quality of Service Oriented Distributed Routing Protocol
Abstract— As Wireless Sensor Networks(WSNs) gains popularity significant research have been devoted to supporting real time transmission with stringent quality of service requirements for wireless applications. Existing work exploits Quality of Service Oriented Distributed Routing Protocol (QOD) for QoS provisioning with delay and energy constraints in WSNs but they are not sufficient to provide quality of service in WSNs. In this paper improve the quality of QOD routing protocol and enhance the Improved Efficient Quality of Service Oriented Distributed Routing Protocol (IEQOD).The improved efficient quality of service oriented distributed routing protocol which combines selfish node isolation method and awake and sleep scheduling to enhance the performance of QOD. Selfish isolation method is the method in which the energy less nodes are isolated from the network and find and alternative route for packet transmission. Awake and sleep scheduling proactively wake-up the nodes in the transmission route and awakened node reduction. Hence we could improve the quality of service in terms of packet delivery ratio, delay and energy consumption. The IEQOD protocol simulated using ns-2 software. Evaluation result demonstrate that IEQOD significantly improve the QOS in WSNs.
