With the development of computer technology and network technology, the network bandwidth consumption and congestion become more and more serious. IP multicast is the best way to achieve this kind of communication. The key of realizing multicast communication is to implement the multicast routing algorithm, namely how to build a simple, effective and robust multicast routing tree. This paper proposes...
The paper proposes one adapt workflow model. We first study the model's execution and control mechanism. Then we study the concept of data association and control association, and use it as the basis to solve the problem of workflow correctness and consistency. We also research dynamic modification and the consistency transformation between the workflows. From the aspects of control flow and data...
WWW is an open and distribution environment, which contains larger number of information. Using ontology can help user to get the network information. Ontology can realize the interoperability and reuse of ontology between each other by referencing relationship. For the rapid growth of WWW and the relative independence between web ontology, so how to integrate the ontology becomes the key problem...
Wireless sensor networks is a multi-hop self-organizing networks system that consist with vast majority of low-cost node arrayed in the monitor area and formed by wireless technology. This paper is oriented to the demand of preferential energy efficiency and brings forward related control algorithm solution to the heated questions about decreasing network energy-consumption and realizing energy-balance...
