IMPROVED NODE FAILURE PREDICTION QOS ROUTING PROTOCOL WITH CLASSIFIED POWER LEVELS

The nodes in ad hoc wireless networks or sensor networks have limited power capabilities and are prone to failure due to lack of battery power leading to frequent path breaks ,network partitions & packet losses thereby resulting in the decrease of network throughput. In this paper , we propose a new routing algorithm called node failure prediction QoS routing with classified power level(NFPQRCL) protocol, which improves the different QoS parameters such as end-to-end packet delay and the packet loss along the path. The algorithm NFPQRCL predicts the future state of a node based on its power level to decide whether the node is a good selection as a router or not .Power considerations at each of the network nodes helps in efficient utilization and saving of battery power. In this algorithm, more stable paths are selected during the route discovery process and hence QoS routing parameter could be satisfied.
