Trust Implementation in AODV Protocol: A Survey

Abstract: A MANET is a network of mobile nodes without a fixed infrastructure. So they do not have a base station or access point to supervise them. Moreover their topology is not constant and keeps changing. These features of MANETS bring in lot of challenges in routing, energy management, QoS issues. They use wireless medium such as air to route the packets. The nodes of MANETs have limited bandwidth, limited resources, and use radio waves where they can be listened passively. These make them suffer from malicious nodes resulting in security breach and the selfish nodes to save their resources without routing. In this paper, we have given a survey of AODV, reactive protocol that has implemented TRUST metric for its enhancement in efficiency to handle the selfishness and the security issues
