In modern time the mobile computing based applications needs advanced data synchronization. In this paper we have developed and investigated the complete database distributed among wireless components as in mobile switching stations. In this approach the entire database is being distributed in wireless components of the computer systems. Some of the parameters that influence and complicate database management are design of database and replication of database. We have developed a mobile environment protocol that can handle the distributed database of several clients using priority based concurrency control mechanism with considerations of Hand Off situation. For this case we have developed our algorithm using MATLAB 2010.An advanced priority queue mechanism is applied to reduce the transaction aborting issues.
