Abstract

A mobile ad hoc network is a set of nodes without the required intervention of any fixed infrastructure. Therefore, these networks have particular application in risk and crisis management should a natural disaster such as flood and earthquake befall and destroy communications infrastructures. In the absence of a fixed infrastructure, nodes in a network need to cooperate with each other. In circumstances as such, a malicious node can easily locate itself on the route and reduce network performance by deleting packets. In this paper, we have proposed a method which enables to detect the malicious nodes using valid and invalid addresses, without triggering false detection across the network. According to the simulation results, this method is capable of detecting malicious nodes faster compared to similar methods.
