Performance Analysis of WAVE Control Channels for Public Safety Services in VANETs
Vehicular Ad hoc NETwork (VANET) is researched for public safety of vehicles. Safety applications exchange the safety messages among I2V (Infrastructure-To-Vehicle) and V2V (Vehicle-To-Vehicle) in VANETs. As several safety applications are running and generating periodic messages on a vehicle, they consume a sizable resources on communication channel. Several organizations identify the high-priority safety applications and recommend safety message generating patterns. These safety messages are carried by WAVE (Wireless Access in Vehicular Environment) and 802.11p standards. The authors analyze the theoretical maximum vehicle number when the high-priority safety applications are running on vehicles on highly congested communication channel condition.
