Abstract
This paper presents research results regarding a vehicle collision avoidance system that uses a wireless sensor platform and communication based on 802.15.4 standard. The system is comprised of two components: monitoring stationary nodes mounted on the road and mobile nodes installed in vehicles. Signal strength and link quality indicators are evaluated to assist in the sequence identification of vehicles as they approach each other at an intersection. The study shows the feasibility of implementing 802.15.4 standard in wireless sensor network communication to act as a time-critical vehicle warning system that can be used for safety application.
