Abstract:
The emergence of Wireless Sensor Networks (WSN) technologies gave rise to the need for abstraction mechanisms that can simplify the data communication tasks. Under this respect, the publish/subscribe paradigms play an important role since they can be used to abstract the WSN in terms that are closer to the needs of applications designed mainly to detect and notify upon events of interests. In this paper, we propose TinyMQ, a content-based publish/subscribe middleware for wireless sensor network. In TinyMQ, an overlay network is constructed on top of the underlying WSN, in which sensor nodes can be logically connected independent of their geographical position. Over this overlay network, message mapping and routing schemes are presented to implement rendezvous-based publish/subscribe. The simulation study demonstrates TinyMQ is efficient in terms of both costs and time.
