: In ubiquitous application scenarios, the information (processing) needs of nomadic users often cannot be satisfied by a set of pre-installed processes like in common workflow systems. Instead, nomadic users require ad-hoc processes that are unique (personalized) and usually do not appear in the same way more than once. As a consequence, ubiquitous applications also require a sophisticated user management such that ad-hoc processes and users may find each other and interact dynamically, for instance, to implement/use location-aware services. In addition, ad-hoc processes must be able to dynamically adapt to changing conditions which often occur in ubiquitous application scenarios. We recently implemented user management, location-based services, and dynamic process changes as an integral part of the AMOR (Agents, MObility, tRansactions) system. This paper sketches these extensions of AMOR towards a prototype system for a peer-to-peer-based ubiquitous process execution environment with...
