MARM: Mobility-Aware Routing Mechanism in Mobile Grid

Mobile Grid is a new type of resource-sharing network, which is featured with large-scale, heterogeneous, dynamic and mobile. Layered architecture is proposed for mobile grid based on the concept of overlay network, and we focus on routing mechanism to support mobility on overlay network layer. Mobility-aware routing mechanism (MARM) proposed in this paper combines distributed hash table technology with the idea of mobile IP. Mobile node doesn't participate in routing process directly, but update its location information dynamically to DHT network which is composed of agent nodes. We evaluate MARM from theoretical analysis and simulation.
