Abstract

Nowadays, as the mobile services become widely used, there is a strong demand for mobile support in P2P search techniques. In this paper, we introduce a new cost model for searching multi-dimensional data in mobile P2P environment and propose a novel multi-dimensional MP2P search scheme MIME. MIME models the physical node layout in a two-dimensional plane and keeps records of the locations of the nodes to construct a proximity-aware P2P overlay. MIME also incorporates two adaptive features: an update algorithm that makes dynamic updates to the overlay, and a cache mechanism that reduces the load of data migration during the updates. Experiment results show that MIME achieves significant performance improvements in point/range queries compared to the conventional system.
