Abstract
Mobile computing is developing fast and one of its major services is location dependent information services (LDIS).The dependence of the results of a query on the present location of the mobile user leads to such services. The query is called Location Dependent Query and the resultant data is called Location Dependent Data (LDD).The caching scheme often used in these services is semantic caching where information about data is stored along with data in cache. In this paper, we have added a new dimension, segment frequency (S) to the Semantic segment. The cache replacement policy takes this dimension into consideration when replacing the cache. The prediction algorithm Enhanced RBFNN (ERBFNN) takes the future location of neighbors into account. The existing FAR algorithm is modified taking into account the new dimension to replace items from cache. The proposed system is called Enhanced RBF-FAR (ERBF-FAR) algorithm. The experimental results show that the proposed system performs better and yields better results.
