Research Of Anonymity Routing Protocols Of Ad Hoc Networks And NS2 Simulation

The wireless Ad Hoc networks composed of mobile terminal nodes with wireless communication device are typically characterized by their multi-hop, temporary and un-center. It can be quickly built up in anywhere and at anytime and every terminal can move freely and be equal. The topology of Ad hoc is dynamically changing. The bandwidth and energy are also limited, etc. Because of these, the research on the Ad hoc network, in particular, the research on its MAC and routing protocols is immensely challenging.This paper, at the beginning, introduces the characteristics, applications and architecture of the Ad hoc network. Next, it describes the existing routing protocols, and explains the principium and the process of working of dynamic routing protocol (DSR) in detail; meanwhile it also introduces the anonymous communication and onion routing. Then, on the basis of the foregoing statement, a new anonymous routing protocol based on DSR is proposed, called ADSR routing protocol.Then, NS2 (Network Simulator Version 2) is introduced in the paper, which is the open-source platform of network simulation and this paper does simulations upon ADSR. Finally, the conclusions of this paper are shown and the problems for future research and perfect are given.This paper concentrates on these: the theory of the onion routing applied to the traditional network successfully is introduced into the Ad hoc network. combining the theory with DSR, protecting the routing information and checking the identity with asymmetrical cryptography, and these greatly improve the security of DSR and the capability of defending attacks.
