MSR: A Novel MPLS-Like Secure Routing Protocol for Mobile Ad Hoc Networks

Protecting sensitive routing information is very fundamental and critical in mobile ad hoc networks (MANETs)that operates in hostile environments,  which  also  bring  great  challenges. Recent research have been focus on  secure  routing, however, most of them relies on cryptographic infrastructure, and which greatly limits their usage. To overcome these drawbacks, we propose MSR, a novel MPLS-like Secure Routing protocol for MANETs, Motivated by the MPLS techniques, MSR integrates the key agreement that doesn’t need the support of online trusted third party and label switching techniques into the secure routing and forwarding process. By establishing multiple label switching paths within the key agreement process, MSR is   resistant to  traf¿c  analysis attack, and provides the desirable identity and  relationship anonymity  through  multiple  pseudonyms and local label negotiation. We then  implement MSR in Glomosim and conduct  extensive  experiments. The detailed analysis and simulation results show that MSR protocol is very efficient and brings low overhead to the network.
