Selection of Optimistic Nodes for Reputation Based Routing in Wireless Networks

Trust based routing in wireless networks helps in providing secured routes for data transmission. Since wireless networks are subjected to several security threats while processing and transmission of data. Therefore, a system called Node Reputation based Energy Aware Routing (NREAR) scheme is proposed here to provide efficient and secured transmissions of information from one end to other end. NREAR consists of node behaviour monitoring phase and node's energy value monitoring phase together. Nodes behaviour monitoring includes detection of trusted and un-trusted nodes on basis of optimistic and pessimistic behaviours of nodes. In second phase after the detection of optimistic nodes the energy value is calculated. By selecting high energy remained optimistic (trusted) nodes, the data gets transmitted from source to the destination. Simulation results are derived and the performance of the proposed mechanism is proved to be better in terms of achieving higher data packets, accuracy in false node detection and throughput.
