“…The simulation results presented in the paper demonstrate that the proposed protocol outperforms ETSI CAM beaconing, supporting the lower figures of ITS-S tracking error. In [9], a Dynamic Beaconing Scheduling (DBS) adaptive beaconing approach based on the current kinematics of the ITS-S is presented. The beacon generation interval is proportional to the speed of the originating ITS-S: the higher the speed, the lower the beacon generation interval.…”

Cooperative awareness on the road is intended to support the road users by providing knowledge about the surroundings and relies on the information exchange enabled by vehicular communications. To achieve this goal the European Telecommunication Standard Institute (ETSI) delivered the standard EN 302 637-2 for Cooperative Awareness Messages (CAM). The CAM triggering conditions are based on the kinematics of the originating vehicle, which is checked periodically. In this paper, we show that the standardized ETSI protocol may suffer a decrease in communication performance under several realistic mobility patterns. The potential influence of the discovered phenomena on the IEEE 802.11p Medium Access Control (MAC) operation is studied.

Among the most critical issues in VANET are the frequent failures of the route caused by the high mobility of vehicles, the increase of the network overload caused by control messages, and the increase of the data packet delivery time. Short communication route lifetime often breaks down during data packet transmission between the source and the destination vehicles, which results in a relaunch of a new route reconstruction that becomes more frequent and depletes a significant amount of network resources. To face these issues, much research has considered the route stability and the route lifetime determination between source and destination vehicles as important factors to improve the quality of service in the VANET network. However, this research did not take into account the route that has the longest lifetime as the most stable route and assumes that vehicles move at a constant speed during a direct communication between them. Furthermore, it did not model the data packet delivery time between the source and the destination vehicles. For this reason, we propose two protocols that use vehicles density to predict the data packet delivery time before sending the data and use vehicles movement information to determine the longest lifetime route, taking into account the variation of the vehicles velocity for comfort applications on highway. Our schemes are evaluated in function of vehicles density by measuring the average route lifetime, the percentage of packets delivery, the control overhead, the average end-to-end delay, the throughput, and the average number of route failures generated during the transmission of data packets.

“…To address the above problems, it is necessary to study the resource coordination among RSUs and the vehicles' adaptive beaconing method together. Existing researches have proposed adaptive beaconing methods aimed at increasing the beacon reception ratio and/or location tracking accuracy in vehicular networks [10][11][12][13] . In Ref.…”

“…In Ref. [13] an adaptive neighbor item expiration time and beacon rate scheme was proposed in order to improve the awareness of the surrounding vehicles according to their position, speed, and orientation. However, these studies adopted the CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) mechanism to access the channel, which could result in potential collisions due to hidden terminals.…”

In vehicular networks, the exchange of beacons among neighboring vehicles is a promising solution to guarantee a vehicle's safety. However, frequent beaconing under high vehicle density conditions will cause beacon collisions, which are harmful to a vehicle's driving safety and the location tracking accuracy. We propose an ABIwRC (Adaptive Beaconing Interval with Resource Coordination) method for a highway scenario. Each vehicle broadcasts beacon interval requests, including the intervals needed for both the vehicle's driving safety and location tracking accuracy. The RSU(Road Side Unit) allocates resources for a vehicle's beaconing according to the requests from all vehicles and the interference relationship between the vehicles in adjacent RSUs. We formulate a resource allocation problem for maximizing the sum utility, which measures the satisfaction of vehicles' requests. We then transform the optimization problem into a maximum weighted independent set problem, and propose an algorithm to solve this efficiently. Simulation results show that the proposed method outperforms the benchmark in terms of beacon reception ratio, vehicle driving safety, and location tracking accuracy.
