WELCOME!

First ACM Workshop on Vehicular Ad Hoc Networks, Oct. 01 2004 (VANET 2004)

Dedicated Short Range Communications (DSRC) is a block of spectrum in the 5.850 to 5.925 GHz band allocated by US FCC to enhance the safety and the productivity of the transportation system”. ASTM (American Society for Testing and Materials) standardization committee E17.51 is working on the development of a standard. DSRC is a medium range communication service intended to support both Public Safety and licensed Private operations over roadside-to-vehicle and vehicle-to-vehicle communication channels. DSRC complements cellular communications by providing very high data transfer rates in circumstances where minimizing latency in the communication link and isolating relatively small communication zones are important.

PATH and Daimler-Chrysler are active members of the DSRC

1) Design and analyze ad-hoc Medium Access Control protocols to meet the communication requirements of active safety systems on-board the vehicle.  

2) Develop a simulator to analyze DSRC communications with vehicular traffic. The simulator models freeway vehicle traffic, protocols at various layers, and has tools to post-process the output data.   

3) Measure and model the 5.9GHz wireless channel in various roadway environments.  

4) Theoretically analyze the optimality of estimation and control system with information conveyed over wireless network.

5) Build a system to give the vehicle a map of its neighborhood based on vehicle-vehicle and roadside-vehicle communications.

6) Build roadside-vehicle wireless communications for Intersection Decision Support.

7) Study the benefits of wireless communications used for Cooperative Adaptive Cruise Control (CACC) system and its impact at highway merge junctions.
