Interference reduction aware optimal route path establishment in wireless sensor network environment

Abstract

Reliable data retransmission without collision is the most concerned research issues in the real world environment with increased interference effects. This is focused and achieved in our previous research method by introducing the method namely Location and QoS Guaranteed Routing Technique (LQoS-RT). In this research method, optimal and reliable routing is performed by constructing the route path with the concern of location details. However this research method failed to focus on the interference effect which affects the reliable data transmission. And also computation overhead of the previous research method is high by analyzing each technique for the interference measurement. This is focused and resolved in the proposed work by introducing the Interference Reduction aware Optimal Routing Scheme (IRORS). Here initially clustering is performed to group the nodes that lie within same transmission range. The cluster head for each cluster is selected with the concern of interference whereas in the previous work cluster head selection is done based location information alone. The node with the low interference probability is selected as cluster head thus the data communication decision can be made without any data loss due to interference. Here the optimal cluster head selection with less probability of interference is selection by applying hybrid firefly particle swarm optimization algorithm. And then optimal routing is performed by adapting the modified AODV routing protocol. In order to make sure the optimal and reliable routing without interference coefficient of restitution value is calculated periodically. If the interference probability is high then rerouting is performed. Likewise the optimal and reliable routing without interference is guaranteed. The performance assessment of the research work is conducted in the NS2 simulation environment from which it is proved that the proposed research method ensures the better performance than the existing work.
