OPTraCom - Opportunistic Public Transport Communication
Motivation
An area wide collection of different sensor data within metropolitan areas opens up a large application range. One example is air pollution that can be measured in fine-granular way, in order to inform residents more comprehensively and optimize the traffic management in the city area. Public means of transport operate regularly and approximately in the entire city. Thus, they well suited for this purpose. They cannot only collect environmental data, but also seize operational data from technical equipment along the roadside. Presently, an efficient networking to for the prompt evaluation of the collected data cannot be realized with private or cellular mobile radio solutions at reasonable costs. In this cooperative project between the BBR Verkehrstechnik and the Institute of Operating Systems and Computer Networks at TU Braunschweig we plan to develop a novel disruption-tolerant communication system on basis of WLAN. Thereby, vehicles store the collected data, exchange them among themselves and this way transport it gradually to the receiver. An area-wide infrastructure becomes is not needed. The main research aspects within this project are efficient strategies for routing and data dissemination within the network. The efficiency of the system will be evaluated with the help of real-world experiments in the city of Braunschweig. The results will help us to examine the system's potential for further applications.Main Research Topics
The main research topics we deal with in the context of Optracom are in the following fields:
- Routing mechanisms for DTNs
- Information dissemination in public transportation networks on the basis of DTNs
- Field tests for analyzing the DTN performance in real environments
Publications
Further publications are in preparation and under review. For further information we also provide publications in which we established the basis for the Optracom project.
