Abstract

Due to the inherited limitations on the connection qualities and available bandwidth in the mobile networking environment, mobile units (MUs) have been unable to effectively access location based services. This paper proposes a two tier Location Dependent Information Services (LDISs) architecture to calculate pre-fetching information values (PIV) for each location dependent data (LDDs). In this architecture, a proxy server will provide MUs with the LDDs that are attached with the relevancy value to reduce response time and workload for the remote database server.
