A framework of community inspired distributed message dissemination and emergency alert response system over smart phones

In this paper, we propose a framework for distributed dissemination of messages over the GSM network by leveraging the capabilities of smart phones. The major contribution of this work is an implementation of a broker-based peer to peer protocol for prioritized delivery of messages in order to support a fast emergency alert and response mechanisms. We have implemented a distributed phone book for controlled dissemination of messages along with a framework for handling responses appropriate to alert messages. In particular, our focus is on the origin and theoretical rationale of system design and the implementation of Data Cart and Data Cart Tracker. The two key features we have preserved in the implementation are: (i) energy efficiency, and (ii) prioritized delivery of messages.
