A number of prefix delegation-based schemes have been proposed to solve the route optimization problem in NEMO, where a group of hosts move together as a mobile network. The schemes trade off between inefficiency of routes and various overheads. With the rapid growth of mobile computing, this
overhead will give rise to the scalability issue of these schemes. However, there has been no quantitative study on the asymptotic scalability analysis of these schemes. In this paper, we have developed analytical models for scalability analysis of these schemes in terms of network size, mobility rate, distance between
mobility agents, and traffic rate. Our analysis shows that the prefix delegation-based schemes exhibit asymptotically identical overhead on the network, and they show better asymptotical scalability in terms of number of mobile routers. The analytical framework for scalability analysis presented in this paper will help in visualizing the effects of future network expansion on the performance of these route optimization schemes of NEMO.

    ABSTRACT: We consider a scenario where a number of mobile networks, e.g. vehicles equipped with Mobile Routers, travel together interconnected in a dynamic mesh structure, here called Ad Hoc Interconnected Mobile Network or AIMNET. The mesh topology interconnecting the mobile networks not only facilitates inter-mobile-network communications, but more importantly allows sharing of Internet access available to individual Mobile Routers. We first discuss the route optimisation problem in AIMNET and the prefix delegation based solutions. We then propose a two-level addressing scheme that minimises the overhead and improves route optimisation. Then, we discuss routing in the AIMNET and provide experimental results to verify our proposals.
