Abstract

There are many researches use peer-to-peer model to organize the Grid Information Service (GIS) and have been testified which be able to improve scalability and reliability of Grid environment. However, Data Grid Information Service (DGIS) has its special requirements and all approaches of P2P model used in GIS cannot be applied to DGIS. In this paper, we propose a new approach for DGIS that imposes a deterministic P2P shape based on hypercube topology, which allows for very efficient query broadcasting. Furthermore, we proposed a transposition algorithm to optimize the overlay network's topology according to the access statistics between peers, making the peers always access each other become neighbor by transposing peer's place. The simulation shows that the transposition algorithm could significant improve searches efficiency.
