How to realize such an exciting idea poses many challenges, and a new approach is needed to provide...
Publish/subscribe (pub/sub) systems are very suitable for the dissemination of dynamic information over the Internet. As dynamic information is usually characterized by a short lifetime, both publishers and subscribers may specify the delay requirement on message delivery.

In this paper, we introduce the semantic Web technologies into the publish/subscribe systems and propose a new type of publish/subscribe system. In the system, concept models are represented as ontologies, events are represented as RDF graphs, and subscriptions...
The design of micro-mobility management protocols stands out as an important challenge in integrating wireless networks into the IP-based Internet, especially when such networks are deployed for real-time multimedia applications. We present a new load balancing hierarchical model for micro-mobility management for the wireless access network. The scheme includes a novel anchor selection algorithm....
