New reflective and reliable context-oriented event service architecture for pervasive computing

Conventional middleware technologies lack the support for handling dynamic aspects of the new pervasive computing environment. Reflective middleware is a principal and efficient system which can deal with ubiquitous environment. It can reliably and quickly deliver important events and filter useless ones. In this paper we propose a new reflective and reliable context-oriented event service paradigm. The proposed event service supports reliable communication as well as reflective filtering through the adapters. It also supports reflective and dynamic context-oriented channel management for evenly distributing the load. An experimentation with six PCs reveals that the proposed scheme outperforms an existing popular commercial middleware in terms of event delivery speed. The improvement gets more significant as the size of event increases.
