Data Traffic Reduction for Mobile Agent Migration

In this paper, we propose a method of reducing data traffic on mobile agent migration. Mobile agents are able to simplify network programming with autonomous process migration as compared with inter-process communication. However, mobile agents increase data traffic by transfer of program codes when migration. Therefore, many researchers have proposed for reducing data traffic on mobile agent system with agent behaviour. These methods complicate the algorithm of agent behaviour. On the other hand, we focus on a mechanism of mobile agent migration, and our method is fully independent from agent behaviour. Our method reduces program code traffic with cache on mobile agent runtime environment. We have implemented our technique on a mobile agent framework, and experimented on a practical mobile agent system. As a result, the system’s performance has improved to 52%.
