PSMR: Publish/Subscribe Multi-cast Routing for Wireless Ad Hoc Networks

With the widespread deployment and use of wireless data communications in the mobile computing domain, middleware as a mobile connector applied in distributed and potentially heterogeneous environments is in great need. Pub/sub scheme with the strength of asynchronously, loosely coupled form of interaction between multi-points, so the middleware based on pub/sub scheme is well adapted to the dynamic, distributed interaction in large-scale mobile computing applications. In this paper, we describe the integration of the middleware based on pub/sub scheme and the multicast routing protocol of mobile ad-hoc network, and present a multi-hop routing subscription (publish / subscribe multi-hop routing) protocol, named PSMR. PSMR helps to distribute the publisher's data to subscribers and establish a pub/sub multi-hops network at the same time, and cooperate the layer of pub/sub scheme and the layer of routing work to distribute the data to make the transmission more reliable.
