ABSTRACT
This paper presents a Reputation-Trust (RT) system that can be used to stabilize the performance of the network for the working nodes even in the presence of malicious nodes which intentionally do not route and forward packets send by others correctly. The situation becomes even worst when nodes do not rely on any routing infrastructure but relay packets for each other. We introduce two extensions to the Dynamic Source Routing algorithm (DSR) [1] to mitigate the effects of routing misbehavior: the watchdog and the pathrater. Using these two approaches, the proposed RT system will update the RT table of each node with the ranked values of other nodes. The implementation of the proposed RT system is entirely based on the underlying proposed RT algorithm. Simulation results demonstrate that the RT system can be used to reduce the malicious behavior of mobile nodes and consequently improve the overall performance of MANET.

Recommendations
Efficient, Secure, Dynamic Source Routing for Ad-hoc Networks
Routing is a must for networks that do not have a fixed point-to-point infrastructure, such as in an ad hoc wireless network that offers unrestricted mobility. A source node in such a network can communicate with a distant destination node after finding ...
Bloom filter based secure and anonymous DSR protocol in wireless ad hoc networks
Wireless ad hoc networks, especially in the hostile environment, are vulnerable to traffic analysis which allows the adversary to trace the routing messages and the sensitive data packets. Anonymity mechanism in ad hoc networks is a critical securing ...
Delay and traffic based on-demand routing algorithms for improving energy efficiency in mobile ad hoc networks
Reducing power consumption and increasing battery life of nodes in an ad hoc network require an integrated power control and routing strategy. The control is better attained by new route selection mechanisms for MANET routing protocols, which we call ...
