Zone-Based Update Strategy for Location based Services (LBS)

Location-based service (LBS) is one of the most important applications related to GIS. In the past few years, there has been a rapid expansion of activities in LBS providing pedestrians with easy access to useful information whilst travelling from one place to another. LBS systems use the power of mobile networks to locate a user and provide data and services based on the location they are in. In view of the fact that the volume of this information is huge, this paper presents a new database update mechanism which will enable improvement of performance of the service provided by LBS Systems. Such mechanism will reduce the usage of network bandwidth which will contribute in minimising the power consumption of the user’s device (Mobile Smartphone, PDA ...etc.). This is because the mobile device receives less information and avoids uploading any superfluous data.
