Implementing and testing a driving safety application for smartphones based on the eMDR protocol

Vehicular Ad-Hoc Networks (VANETs) offer opportunities for improvements in driving security and comfort. Vehicles can take advantage of collaboration schemes to disseminate important information. In this article we present a a driving safety application based on warnings dissemination for smart-phones based on our eMDR protocol. The use of smartphones allows a quick development and deployment, avoiding the cost of specific hardware. Additionally, since most users are familiar with the use of smartphones, this alleviates the adoption barrier. Our application is integrated into a Navigation System which allows accessing road maps, current location and route information through an interface that we have created. We have analyzed the behavior of the wireless channel and the GPS location service under different conditions to assess the feasibility of our proposal. Result showed that, in C2C communications, smartphones provide a reasonable connectivity and enough precision even for certain type of driving safety applications.
