Implementation and Experiment of Publish/Subscribe System on Wireless Mesh Networks - Word-Mouth Information Distribution Service

Publish/subscribe (Pub/Sub) systems can disseminate information scalability. This systems also enable users to get only their interesting information in real time. We are planning demonstration experiments of Pub/Sub systems as a word-mouth information distribution service (WIDS)for users such as resident, shopper and traveler in Kobe,Japan, with the support of the Strategic Information and Communications R&D Promotion Programme (SCOPE).In this paper, we present a summary of the WIDS, and propose a dissemination tree construction protocol, which is implemented in the WIDS. Then, we show the effectiveness of our proposal protocol on simulation. Finally, we confirm the WIDS implemented operation in real environment experimentation.
