Abstract

newlineThe explosive growth of wireless communication technologies newlinewireless portable devices mobile application standards and supporting newlinesoftware technologies has led to larger usage of mobile data services newlineHowever various constraints such as limited wireless bandwidth client newlineresources remain barriers to the complete utilization of mobile data services newlineData management is a key issue in mobile computing and has newlinearoused much attention since it is challenging to process information on the newlinemove to cope with resource limitations and to deal with heterogeneity newlineAmong the applications of mobile data management Location Based Services newlineLBS have been identified as one of the most promising area of research and newlineDevelopment These services integrate geographical location and enduser newlinecontext dynamically to deliver the necessary information Thus sophisticated newlinedata management and resource management techniques are needed for the newlineenhancement of the performance of these data services newlineA key characteristic of LBS is that the same service request may newlineneed to be answered with complete different results as the user changes his newlinelocation or as the targets move Because of the highly dynamic nature of the newlineproblem traditional information management techniques are not well suited newlinefor LBS newline newline
