Wireless Mesh Networks represent a promising technology to provide wireless Internet connectivity over a large community. This new technology not only allows a fast, easy and inexpensive network deployment, but also enables many new applications including community-scale peer-based communication or sharing of network resources and services. In this work, we propose an effective publish/subscribe communication paradigm to facilitate efficient data dissemination over wireless mesh networks. The proposed publish/subscribe scheme dynamically routes and delivers events and services from sources to interested users with minimum communication overhead and memory storage. The effectiveness of the system is demonstrated through comprehensive simulation studies.
