Pltrust AODV: Physical logical factor estimated trust embedded AODV for optimised routing in Manets

A Mobile Ad hoc Network is a collection of mobile nodes forming network of their own. They have dynamic topology implying their mobility and no central authority implying their dual role as routers as well apart of transmitting and receiving the packets. It is implicit that they pave way for the malicious attacks leading havoc in the network. It is important to have secure transmission in order to increase the reliability in MANETs. Trust is incorporated to achieve strengthened security in MANETs. The proposed work encompasses pertinent aspects to evaluate Trust which comprise of energy, time factor, Packets ratio and signal strength in Ad hoc On Demand Distance Vector Protocol for defending the malicious node's attack and the results are compared with Trust based Optimal link state routing protocol. Two main types of attacks namely Black Hole Attack and Jelly Fish Attack are mitigated in this approach. The analysis carried exhibits transcending performance of the MANETs using the proposed approach compared to OLSR based approach. In specific packet delivery ratio, throughput have got significant improvement while energy consumed and average end to end delay having decreased delivering the effectiveness of the proposed approach.
