Fixing the performance issue of the IEEE 802.11p MAC layer CSMA based broadcast protocol - a summary

The IEEE 802.11p standard specifies the physical and MAC layer operations for interchanging wireless broadcast messages in a vehicular environment and is part of the IEEE WAVE standard for vehicular safety applications. Nevertheless using the IEEE 802.11p MAC layer on scenarios with high node densities results in a congestion issue manifested by low packet reception ratios which might result in further problems for safety services in a vehicular context.

The article motivates the issue through empirical evidence and shows two completely different solution approaches in order to solve the problem. Get & read it now:
