Client mobility in rendezvous-notify

ABSTRACT

Event-based computing is vital for the next generation mobile services and applications that need to meet user requirements irrespective of time and location. The event paradigm is a form of asynchronous one-to-many communication and allows clients to receive information that matches their interests through filtering. Event-based communication is a good candidate for mobile computing, because it is asynchronous and supports disconnected operation. However, user and terminal mobility present problems pertaining to synchronization and delivery that need to be solved. In this paper, we examine and analyze mobility in the Rendezvous-Notify architecture. This event-delivery architecture is based on two server roles: access servers that maintain subscription information and buffered events, and resolution servers that are responsible for event channels and routing events to access servers. Access to event channels is done using a rendezvous mechanism.
