COMPARATIVE STUDY ON TRUST-BASED MODEL AND BLACK HOLE DETECTION AND ELIMINATION IN MANETS

Abstract

A mobile ad hoc network (MANET) is a framework-less network consisting of several mobile nodes with wireless network interfaces. Due to node mobility in MANET, the stability of the network is affected by which the trust value of a node makes it reliable for packet transmission. The evaluation of the trust value of a node depends on three parameters, such as rank, remaining battery power, and stability factor of a node. In this paper, various trust-based models and their advantages and disadvantages have been studied. Various attacks affect the MANET from which the black hole attack is one of the security attacks. The black hole attack can be a single black hole attack or can be a cooperative black hole attack. The two properties of a black hole attack are the malicious node impersonates other nodes of having a valid route to the destination even the route is spurious and, second is the attacker consumes the packets without forwarding them. In order to combat this issue, various solutions have been studied.
