Mitigate Black Hole Attack Using Hybrid Bee Optimized Weighted Trust with 2-Opt AODV in MANET

A Mobile Ad hoc Network (MANET) is susceptible to several security threats. This work aims at securing a MANET against black hole attacks. Based on MANET characteristics, a trust based secure routing protocol known as Ad hoc On-Demand Vector Routing has been proposed, which protects a MANET from black hole attack. This work presents an algorithm which decreases the probability of black hole attacks known as a hybrid Weighted Trust based Artificial Bee Colony 2-Opt algorithm. Optimal secure paths can be detected using the ABC algorithm. The hybridization of the algorithm has been performed using the 2-opt as local search. This algorithm’s efficiency can be improvised using the current solutions on the basis of their fitness for generating new solutions. Proposed method enhances the performance parameters such as packet delivery ratio, hops to sink and end to end delay.
