Mobility support for wireless sensor networks simulations for road intersection safety applications

This paper provides a description of a system for collision detection of vehicles within a simulated wireless network scenario. One kind are wireless sensor networks, which collect environmental data and disseminate them over the network. Another application is the field of car2car communication, which will become more and more important in future. A network of nodes within a car2car scenario is characterized by high dynamics and road safety applications. In this work we present a new concept of combining a simulator for wireless sensor networks and a simulator of road traffic scenarios. Based on this new enhanced simulation environment we developed a first safety application which determines the trajectories of surrounding vehicles and estimates potential collisions.
