A New Network Layer for Mobile Ad Hoc Wireless Networks Based on Assignment Router Identity Protocol

Customers have complained that malicious nodes are mounting increasingly sophisticated attacking operations in mobile ad hoc networks (MANETs). It is obvious that the IP-based MANETs are vulnerable to attacks and therefore are insecure. In this paper, we design a novel assignment router identity protocol (ARIP) to establish a new layer of network architecture and to take full advantage of Dynamic Hybrid Multi Routing Protocol that we have recently developed for MANETs [2]. A new Identity in the flexible namespace of ARIP enhances the limit in forming prevention line in the security of MANET. A complete architecture is then derived as an instantiation of router identity routing protocol (RIRP) model whose architecture satisfies the condition of ARIP model in order to use this new Identify for routers/hosts. All applications in RIRP deal with this new Identity instead of the vulnerable IP addresses and therefore provide the security embedded seamlessly into the overall network architecture. The proposed RIRP have been implemented on the simulator Glomosim. Simulation results show that RIRP has some great impact on routing performance comparing with DHMRP.
