LBG SYSTEM FOR TRANSACTION MANAGEMENT IN MOBILE COMPUTING ENVIRONMENTS

Computer And Systems Dept., Faculty of Engineering, Mansoura University, Egypt.

Mobile transaction problem is a very difficult challenge in the mobile computing paradigm.

Many researchers efforts had been developed to solve this problem with many attractive

techniques. However these techniques did not consider all factors that affect mobile

transaction management. This paper considers such factors by introducing a novel strategy

for managing the mobile transaction. The proposed strategy centralizes computations in the

fixed network instead of transfer them with each hope of the mobile client, using the LBG (

Local, intermediate Buffer and Global transaction manager ) system. Accordingly, results are

available for the mobile client at any time of connection periods through it’s current base

station. Experimental results had shown that the proposed strategy minimizes the

communication cost, processing time, bandwidth occupation. It also supports transaction

mobility and suitable for mobile devices constraints, which increases the overall system

performance.
