Mobile Agent Architecture for Nomadic Computing

Our goal is to de ne a communication architecture for nomadic applications. We notice that the mobile agent paradigm is particularly suitable for nomadic applications. Although many mobile agent systems are being proposed, few of them raise the problem of the interface between applications and mobile agents. We propose to use the MAP (Mobile Assistant Programming) architecture and add a middleware layer that adapts MAP to nomadic environments. The nomadic adaptation layer provides enhanced services to nomadic applications: result collector is managed as a predictif cache, partial or approximate results may be delivered, and network connections are optimized. An application controls the layer by de ning politics to adopt for connection management and result delivery.
