Connected-Vehicles Applications Are Emerging [Connected Vehicles]
TL;DR: The age of autonomous vehicles is fast approaching, according to new survey results by the World Economic Forum, and most city authorities believe that applications such as shared self-driving vehicles are coming very quickly and will have the potential to be the last-mile solution for public transport.

- 23 May 2010
TL;DR: This work studies the MAC mechanism within IEEE 802.11p being a carrier sense multiple access (CSMA) algorithm and compares it with a self-organizing time divisionmultiple access (STDMA) scheme when used for broadcasting periodic position messages in a real-istic highway scenario and shows that STDMA outperforms CSMA of 802.
Time for Autonomous Vehicles to Connect [Connected Vehicles]
TL;DR: To advance safety further, connectivity is needed and communications can be seen as a different type of sensor, providing the nonline-of-sight information that radars cannot.

TL;DR: This paper proposes a solution that instead uses a dedicated service channel for platooning applications and compares its performance to standard-compliant IEEE 802.11p inter-platoon communication on the control channel.

How Severe Is the Hidden Terminal Problem in VANETs When Using CSMA and STDMA
Katrin Sjoberg,Elisabeth Uhlemann,Erik G. Ström +2 more
- 01 Dec 2011
TL;DR: The results reveal that the presence of hidden terminals does not significantly affect the performance of the two MAC protocols and STDMA shows a higher packet reception probability for all settings due to the synchronized packet transmissions.
