An Efficient Deployment Schema of Active Moving Sensor Peers for Location-Based Publish/Subscribe Services

The miniaturization of computing, sensing and wireless communication devices enable the development of wireless sensor networks (WSNs). One of interesting research in sensor networks is utilizing active moving nodes. The benefit of the active sensor nodes is to measure wide-ranging area by small number of nodes. Despite of the rapid development of the network protocols in mobile sensor nodes, the application platforms for active sensor nodes have not been much discussed. In this context, publish/subscribe model is one of reasonable solution with sensor networks. Publish/subscribe model has become a prevalent paradigm for delivering data/events from publishers (data/event producers) to subscribers (data/event consumers) across large-scale distributed network. In sensor networks, a user who is interested in the specific location and attributes can send subscription to the system to receive all desired events. This paper proposes a novel schema that allows us to control active sensor nodes for location-based publish/subscribe system. In our schema, active sensor nodes can be deployed to the most effective location for event delivery.
