Context-based Dynamic Channel Management for Efficient Event Service in Pervasive Computing

In pervasive computing environment a number of distributed applications asynchronously exchange data using the event-based mechanism. The OMG defined CORBA Event Service for asynchronous messaging, which provides a flexible channel for asynchronous communication among the distributed and collocated objects. In the existing Event Service channels are created manually by the developers or users to process and disseminate the events. Also, the channel management is static which may cause bottleneck in some channels. In this paper, thus, we propose a dynamic context-based channel management scheme by efficiently combining name service with event service. It is embedded in the CALM(Component- based Autonomic Layered Middleware) developed by us, which has been implemented based on ORB. Computer simulation reveals that the proposed approach significantly reduces the event delivery and processing time of the existing omni Event Service and TIBCO.
