Along with manifold advantages of distributed multi-agent systems, increased network traffic produced by highly communicative agents in large distributed systems has to be considered as their practical downside. We suggest to apply the programming paradigm of mobile agents to reduce this network overhead by allowing agents to meet at the same network node before commencing communication. A remote communication between two agents could then be replaced by one or two agent migrations, followed by local communication. Since only in trivial cases it is possible to decide at design time whether remote communication or agent migration with subsequent local communication would perform better, this decision has to be made at run-time based on environmental parameters and agents' past experience. We present an adaptive approach, which is inspired by a solution of the El Farol problem. Every agent forecasts the network load of the next communication step and applies a simple mathematical model to decide between the two alternatives at run-time. In addition, our approach does not only consider network load but also server load by enabling agents to dynamically forecast the number of agents migrating to a specific agent server. The approach is evaluated with simulation experiments in static and dynamic server load environments.

Mobile devices enabled with Web services are being considered as equal participants of the Web services environment. The frequent mobility of devices and the intermittent disconnection of wireless network require migrating or replicating Web services onto adjacent devices appropriately. This article proposes an efficient method for migrating and replicating Web services among mobile devices through code splitting. Specifically, the proposed method splits the source code of a Web service into subcodes based on users' preferences for its constituent operations. The subcode with a higher preference is migrated earlier than others. The proposed method also replicates a Web service to other devices to enhance its performance by considering context information such as network traffic or the parameter size of its operations. To evaluate the performance of the proposed method, the effect of the code splitting on migration was analyzed. Furthermore, to show the feasibility of the proposed migration method, three application scenarios were devised and implemented.
