Abstract

Abstract:

Current semantic cache consistent maintenance strategy is difficult to adapt to frequent mobility, hand off and disconnect network environments. The article propose a new semantic cache scheme using mobile agent technology to maintain the cache consistency. Firstly, mobile agents MSSAg and MTAg are designed based on SMC-architecture. Secondly, the process of maintain cache consistency is discussed in two cases: without hand-off and with hand-off. Experiments show that the proposed cache maintenance method could reduce cache consistency restore time and save data communication cost effectively. It is particularly efficient for using in frequent mobility, hand off and disconnect network environments.

Key words: mobile computing, semantic cache, hand off, consistency maintenance, mobile agent
