Ubiquitous network connectivity and Mobile communications have recently attracted many researchers. While implementing Mobile Ad Hoc Networks (MANETs) its major problem security is widely addressed, but various challenges still persist such as the different kinds of misbehavior of node may be exhibits, detection of routing misbehavior and collusion of misbehaving nodes has not been adequately addressed yet. One such solution to overcome selfishly behaving nodes in wireless network is to detect and exclude them .There are several secure routing protocols to detect routing misbehavior in the direct neighborhood. In this paper, we presented an improved version of Leak detector mechanism and iterative probing mechanism to detect colluding malicious nodes, manipulations of route in wireless multi hop networks. Leak detector enables the calculation of the packet-loss ratio for the individual nodes. Iterative probing enables reliable detection of selfish nodes that drop packets in a MANET. Our Simulation results of these mechanisms shows that they are highly adaptable, reliable and most effective way to identify any selfish behaviors, routing and collusion of misbehaving nodes.
