Trust based Ad-hoc on Demand Routing protocol for MANET

Mobile Ad-hoc networks (MANET) is a set of wireless nodes without any fixed infrastructure or base station, in which nodes communicate directly to the other nodes within its transmission range over relatively bandwidth constrained wireless links. MANET is vulnerable to various types of attacks from malicious nodes due to its spontaneous nature of communication and the absence of centralized administrator. There are many attacks in MANET due to which the legitimacy of a network is compromised such as, Black Hole Attack, Worm Hole Attack, Byzantine attack, DoS attack. So, secure communication in MANET is essential and challenging task. In this paper, we present trust based Ad hoc On Demand Routing protocol for MANET. Our proposed algorithm works on the concept of honest value which is calculated on the concept of hop and trust to protect the network from malicious node. The performance of the proposed protocol is analyzed using throughput, number of drop packets, packet delivery ratio and number of received packets with the variation of number of nodes, speed and simulation time. Results show that the proposed method has better performance and enhance the security in the network.
