Abstract : In this paper we investigate the concept of designing user-centric transaction protocols towards achieving dependable coordination in AmI environments. As a proof-of-concept, we propose a protocol that takes into account the schedules of roaming users that move from one AmI environment to another, to avoid abnormal terminations of transactions when the users leave an environment for short, only to return later. We compare the proposed schedule-aware protocol against a schedule-agnostic one. Our findings show that the use of user-centric information in such situations is quite beneficial.
