Application deployment on Wireless Mesh Networks (WMNs) is a
challenging issue. First it requires communication abstractions that
allow for interoperation with Internet applications and second the
offered solution should be sensitive to the available resources in
the underlying network. Loosely coupled communication abstractions,
like publish/subscribe, promote interoperability, but unfortunately
are typically implemented at the application layer without
considering the available resources at the underlay imposing a
significant degradation of application performance in the setting of
Wireless Mesh Networks. In this paper we present SPINE, a
content-based publish/subscribe system, which considers the
particular challenges of deploying application-level services in
Wireless Mesh Networks. SPINE is designed to reduce the overhead
which stems from both publications and reconfigurations, to cope
with the inherent capacity limitations on communication links as
well as with mobility of the wireless mesh-clients. We demonstrate
the effectiveness of SPINE by comparison with traditional approaches
in implementing content-based publish/subscribe.
