A Communication Middleware for Scalable Real-Time Mobile Collaboration

Applications such as transportation management and logistics, emergency response, environmental monitoring or mobile workforce management, employ mobile networks as means of enabling communication and coordination among a possibly very large set of mobile nodes. The majority of those systems thus may require real-time tracking of the nodes, interaction with all participant nodes, as well as means of adaptability in a very dynamic scenario. In this paper we present a middleware communication service that supports real-time tracking of several thousands of mobile nodes, demand adaptability, as well as three modes of communication between the nodes: unicast, group cast and broadcast. We then show Fleet Tracking and Management system and use it to evaluate our middleware.
