Transactional Mobility in Distributed Content-Based Publish/Subscribe Systems

This paper formalizes transactional properties for publish/subscribe client mobility and develops protocols to realize them. Evaluations show that compared to traditional protocols, those developed in this paper, in addition to supporting transactional properties, are more stable with respect to message and processing overheads. Changes in factors such as the number of moving clients have little impact, making the protocols more scalable and simpler to administer due to predictable resource requirements.
