Data Management in Mobile P2P Systems

Abstract

We focus on effective data sharing in mobile P2P system. In order to realize data sharing, data have to be stored in the system so it can be retrieved by every peer. Our data sharing mechanism consists of a data storing method, a query processing method, and a data dissemination method. We adopt a limited search approach for the query processing in order to retrieve data effectively in highly mobile environment. Therefore, the goal of the data storing method is to distribute data in wide area. We adopt data hashing approach for the data storing method and propose data distribution algorithm HID and redundancy control algorithm ARw/D. Our results show that HID with ARw/D performs significantly well.
