An Efficient Migration Scheme for Mobile Agents in Ubiquitous Environments

Along with the development of lots of mobile agent platforms, the various researches on migration schemes for mobile agents have been suggested. The agents play a key role to manage a huge amount of tasks instead of human being in ubiquitous computing environments. During their operations, agents may cause excessive overhead of network traffic because the size of agent code continuously becomes bigger than before as the increasing complexity of its functionalities. In addition, there is one additional possibility that frequent visits by a lot of agents make target platforms be the bottleneck of communication. To solve these problems, we suggest a new approach. The proposed scheme is to cache the codes of mobile agents which bases on frequent visiting of platforms in ubiquitous environments. To show superiority of our scheme, we compare the proposed method with the existing methods through various simulations.
