Zone-based update mechanism for Location Based Services (LBS)

In the past few years, there has been a rapid expansion of activities in location-based services (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 users and provide data and services based on their location. In view of the fact that such systems suffer from sending huge volume of information from the server to the user, this paper presents a new update mechanism which improves the performance of the service provided by LBS Systems. Such mechanism will reduce the usage of network bandwidth which will contribute in minimising the memory and power consumption of the userpsilas device (mobile smartphone, PDA... etc.).
