Abstract
A Sentient Computing environment is one in which the system is able to perceive the state of the physical world and use this information to customise its behaviour. Mobile agents are a promising new programming methodology for building distributed applications with many advantages over traditional clientserver designs.We believe that properly controlled mobile agents provide a good foundation on which to build Sentient applications.
The aims of this work are threefold: (i) to provide a simple location-based mechanism for the creation of security policies to control mobile agents; (ii) to simplify the task of producing applications for a pervasive computing environment through the constrained use of mobile agents; and (iii) to demonstrate the applicability of recent theoretical work using ambients to model mobility.
