We describe a problem of redundant flooding induced by multiple sensor nodes during route discovery in event-driven wireless sensor networks, and propose a novel extension to the on-demand ad hoc routing protocol, in order to reduce the number of signaling messages during the route discovery phase. That is, our extension reduces energy consumption during route discovery. The heuristically and temporarily selected Path Set-up Coordinator (PSC) plays the role of a route request broker that
