Vehicular Ad-Hoc Networks to Avoid Surprise Effects on Sparsely Trafficked, Rural Roads
This paper summarizes the main results from a project focusing on the development and evaluation of communication protocols for inter-vehicle communication on sparsely trafficked, rural roads, ensuring the reliable and timely delivery of safety-critical data. The project is motivated by traffic safety applications, especially warning systems to avoid surprise effects of unexpected vehicle encounters on sparsely-trafficked, rural roads. The key issue in such an application is to make sure that the vehicles become aware of each other's existence by the help of communication as soon as possible. The driver can then be warned in time to avoid a possible accident. The challenge is to gain high probabilities of successful delivery in time, especially when having to cope with bad communication performance caused by e.g. crests.
