Testing viability of relay policies for reactive CCA applications in VANETs
2010 IEEE 6th International Conference on Wireless and Mobile Computing, Networking and Communications
Relaying mechanisms for Chain Collision Avoidance (CCA) applications in Vehicular Ad-hoc Networks (VANETs) are crucial when one hop transmissions are not enough to reach all of the vehicles in a platoon at risk of accident. Taking into account that CCA-related information must be distributed to as many vehicles as possible in the shortest affordable time, a reasonable way to determine the viability of using such relay policies is by evaluating the delay to spread information to all recipients
... to all recipients and the associated occupation of the communications channel. Furthermore, the inherent transition to reach full technology penetration in the market requires to study how the system of vehicles will behave at different stages of deployment and how different relaying mechanisms may affect the general functionality of the system and what is the influence of background data traffic which can obviously worsen the successful delivery rate (SDR) of warning notification messages.
