%X We describe a system that permits maintaining the software installed on several heterogeneous computers distributed over a network by taking advantage of the mobile agent paradigm. The applications are installed and updated only on the central server. When a new release of an application is installed on the server, agents are scattered along the network to update the application on the clients.To build a prototype system we use X-KLAIM, a programming language specifically designed to program distributed systems composed of several components interacting through multiple tuple spaces and mobile code. %D 2002 %L eprints322 %K distributed software update, mobile agents, mobile code %A Lorenzo Bettini %A Rocco De Nicola %A Michele Loreti %R 10.1145/508791.508800 %B Proceedings of the 2002 ACM symposium on Applied computing (SAC '02) %P 32-36 %T Software update via mobile agent based programming %I ACM %O ACM ID: 508800
