Mitigate black hole attack using bee optimised weighted trust with AODV in MANET

Abstract

Mobile ad hoc network (MANET) is a decentralised network that can be used without any fixed setup or infrastructure and offers unlimited opportunities in all fields. Both the advantage and disadvantage of this mediums is the wide transmission range of the network that exceeds the area where the network is deployed, giving great opportunities for intruders to hack the network thus making it an unsafe mode of transmission. The conventional approaches for security attacks require high memory and high power consumption and so they cannot be used to tackle the security attacks for ad hoc routing. In this work, trust is used for addressing the maliciousness in the network. In this paper, the proposition is to reduce black hole attack in MANET using artificial bee colony optimisation for finding optimal secure routes. Proposed method outperforms the performance metrics like packet delivery ratio (PDR) and number of hops to sink. Also performs as normal effect for end-to-end delay.
