Trust-Based Routing Mechanism in MANET: Design and Implementation

摘要

Mobile Ad hoc Network (MANET) is a self-organizing wireless network for mobile devices. It does not require any fixed infrastructure to be configured which makes it more suitable to be used in environments that require on-the-fly setup. This paper discusses the challenging issues in MANET routing security. It presents FrAODV, a trust-based scheme for securing AODV routing protocol in MANET using the friendship mechanism. The nodes can evaluate the routing paths according to some selected features (such as node reputation and identity information) before forwarding the data through these routes. We have used two types of implementation in our scheme, simulation (using NS2) and real test-bed (using JADHOC). This scheme is believed to provide a robust environment where MANET nodes can trust each other in a secure community.
