Zigbee based VANETs for accident rescue missions in 3G WCDMA networks

This paper provides a comprehensive approach towards developing an efficient emergency response system to manage rescue missions of vehicular accidents occurring at remote locations with the aid of Vehicular Ad-hoc Networks (VANETs) deployed in a third generation (3G) Wideband CDMA (WCDMA) cellular network setup. The system utilizes Zigbee for tracking the vehicular positional coordinates and resorts to WCDMA for effective voice communication. Completely analyzing the individual elements of the network architecture and executing their configuration, the paper proceeds on to develop a complete information flow between the afflicted vehicle and the emergency response station considerably involving the Transport and MAC layers.
