Hybrid DHT Design for Mobile Environments

In this paper we present a hybrid design concept for Distributed Hash Tables (DHTs), in order to increase the performance of DHTs in scenarios with mobile participants. By defining two classes of nodes (static and temporary) and assigning critical overlay networking tasks to reliable static nodes, our concept; allows the disburdening of resource-constrained temporary nodes such as PDAs or mobile phones. Further we present an implementation of our system design, based on the Chord protocol, in the Network Simulator 2 (NS-2) and in the overlay simulator L7Sim and show simulation results that prove the significant advantages of our extension in comparison to conventional DHTs.
