A Resilience Wireless Enhancement for Neighborhood Watching System

Free registration required

Executive Summary

In order to provide a more resilient communication for a NeighborHood Watch type (NHW) system, a mobile middleware architecture using Delay-Tolerant Network (DTN) technology and publish/subscribe concepts is described. The purpose of the middleware is to add resilience and reach to wireless communications, and also to reduce the battery drainage of the mobile devices, hence extending their operational lifetime. A prototype developed on the Android mobile platform is presented and the effects of multiple radio access, routing algorithm and application activity on energy efficiency are investigated.
