Abstract

In this paper, we describe the Optimized Route Cache Management Protocol (ORC) as a network mobility protocol and evaluate it through experiments on a prototype implementation. ORC provides mobility transparency to a network regardless of network movements. Mobile network is a network which the network moves entirely. Typical examples for a mobile network is Personal Area Network (PAN) and a network inside vehicles. ORC is based on Mobile IPv6 [16], and it is combined with the internet routing mechanisms for network's mobility managements. ORC assigns a unique unchanging subnet prefix to a mobile network, and notifies and maintains a mobile network's route called Binding Route (BR). A BR is an association between the prefix of the mobile network and a current available address known as care-of address in Mobile IPv6. ORC allows Interior Gateway Protocol (IGP) routers named ORC routers to cache a BR. ORC routers intercept packets destined to the mobile network and route them to the mobile network according to the BR. The BR must be updated as soon as the mobile network changes the care-of address by its topological position, employing constant BR exchange to ORC routers and temporarily BR exchange to dynamically discovered ORC routers. Based on the experimental results, ORC is confirmed to provide network mobility and optimal communication in terms of route optimization. The evaluation shows that route optimization is required for network mobility to improve communication performance.
