A middle-tier approach for scheduling the work log of employees using Location Based Services

This paper presents a mobile application based on providing Location Based Services (LBS) using Global Positioning System (GPS) as a location provider. The main objective of this work is to design and implement a client server system that helps the system to know the location of their employees and also alerts the employee when they are nearby. The mobile application was implemented using J2ME where the most recent APIs and other older APIs were combined together in order to make the application reliable on all types of mobiles. The server was implemented using J2EE technologies. The type of the Database used in the system was MySQL. The average location accuracy of the application is about couple of meters.
