Abstract
Mobile agents have emerged in the mid-90s. They are programs that can start execution in a host, suspend execution, then move to another host to resume execution. The current Internet infrastructure comprises an extensive range of hosts. Clients range from high-end personal computers (PC) with a lot of memory capacity / processing power, to memory capacity / processing power constrained personal digital assistant (PDA). Mobile agents that roam the Internet need to adapt to these constraints. This paper proposes a novel architectural framework for adapting mobile agents to host variation. Its focus is on adaptation to memory constraints. The framework consists of dynamically partitioning the agent when memory is scarce, and re-assembling it when memory is abundant. We have applied it to the mobile agents of a service architecture for Internet Telephony. The results including the prototype and the measurements are presented. They indicate that the overhead due to the partitioning / re-assembling is low. This makes the framework very appealing, especially as it can be applied to any mobile agent, provided that the set of basic assumptions we have made is valid.
