摘要：Mobile ad hoc networks (MANETs) are increasingly adopted in both military and civilian usesdue to its self configuration and self-maintenance capabilities. MANETs are higly vulnerable to security threats due to inherent charateristics as wireless transmission , lack of fixed infrastructure , dynamically changing topoly, etc. The broadcast nature of the wireless medium makes MANETs susceptible to various malicious attacks. Traffics annalsis is one of the most serious security attacks in MANETs. For instance , in a battle field the enemy can physically destroy the important mobile nodes if they can identify and locate suck nodes by traffic analysis . In order to thwat such attacks , ananymous communication protocols are developed. For the purposes of security and robustness , an ideal anonymous routing protocals as in the route, in particular , those of the source and the destination. Multiple routes should be established to increase the difficulty of traffic analysis and to avoid broken paths due to node mobility . Existing schemes either make the unrealistic and undesired assumption that certain topological information about the network is known to the nodes , or cannot achieve all the properties described in the above . In the paper , we propose an anonymous routing protocol with multiple routes called ARMR, which can satisfy all the required properties. In addition, the protocal has the flexibility of creating fake routes to confuse the adversaries , thus increasing the level of anonmity. In the terms of communication efficiency , extensive simultion is carried out. Compared with AODV and MASK , our ARMR protocol gives a higer route request success rate under all situations and delay of our protocol is comparable to the best of these two protocols.
