“…The medium access control (MAC) protocol largely influences the delay if the link is shared among multiple devices. Sending and receiving a packet involves a context switch in the operating system, which takes a finite time [30], where distance it takes more time to reach the destination if the distance of the medium is longer and velocity if the velocity (speed) of the signal is higher, the packet will be received faster. Jitter is a variation of the arrival time of data packets.…”

Software defined network (SDN) is a new approach concept for planning, developing, and operating computer networks. Routing is the process of selecting paths on a network system to send or forward packets to the destination network. This study aims to obtain the results of the calculation analysis using the k-nearest neighbor (k-NN) method as the implementation of the recommendations. The results of the analysis use a mesh topology design approach with predicted values of throughput, jitter, delay, and packet loss. This value is used as a recommendation to the network manager to determine the best path. The best path selection from the analysis results is i) path-1 (very good) which includes switch 1, switch 2, and switch 4; ii) path-2 (good) to switch 1, switch 3 and switch 4 switch 4; iii) channel-3 (moderate) through switch 1, switch 2, switch 3 and switch 4; and iv) channel-4 (bad) through switch 1, switch 3, switch 2, and switch 4. While the calculation using the confusion matrix is accuracy=72.31%, precision=96.08% and recall=87.84%.

“…However, relying only on static position fields may fail to promptly propagate alerts through changing topologies. Furthermore, [27] proposed the Velocity and Position-based broadcast suppression protocol to minimize storms through source vehicle metadata, avoiding periodic exchanges. Receivers calculate forwarding probability based on distance and speed.…”

Unexpected traffic incidents cause safety concerns and intense traffic congestion on crowded urban road networks. Vehicular ad-hoc network (VANET)-aided Intelligent Transport Systems (ITS) aim to mitigate these risks through timely dissemination of alert messages. However, conventional Radio frequency (RF) mobile ad-hoc routing protocols are ill-suited for dynamic VANET environments due to high mutual interference, packet collisions, high end-to-end delay from frequent route discoveries, and periodic beaconing requirements. Fortunately, the quickly emerging Visible Light Communications (VLC) provide complementary short-range connectivity with high bandwidth and low interference. This paper proposes an efficient adaptive routing protocol for emergency messages in dense VANET scenarios leveraging a hybrid RF/VLC system. When an incident or congestion happens, the source vehicle disseminates the information to the incoming vehicles as quickly as possible using a combination of VLC and RF communication networks. Multi-hop relays extend the connectivity if the direct links are blocked. The coverage area is partitioned into zones based on road segments, intersections, and traffic flows. The Road Side Units (RSU)s are intelligently assigned to zones and they analyze the historical traffic data to characterize each zone and decide a response strategy. We also propose a congestion detection scheme that utilizes traffic simulations to forecast the clearance times under different response strategies. The highest-scoring strategy is selected based on the predicted impacts on travel time, emissions, and driver stress levels. The proposed algorithm adaptively uses the selected strategy to proactively alleviate the predicted congestion through optimized routing and control. Overall, the protocol maximizes safety and efficiency during emergencies by leveraging the hybrid RF/VLC, incorporating real-time congestion forecasting and dynamic rerouting into the response strategies.

“…Khan et al in [97] proposed a velocity and position-based broadcast suppression approach for VANETs (VP-CAST) to exchange safety messages for the avoidance of accidents and deal with emergency messages efficiently if an accident happened both in a sparse and dense scenario. A suppression mechanism is used to avoid a collision, and if the network is disconnected, vehicle services coming from opposite directions are taken.…”

“…Despite that, the communication overhead offered by the total amount of transmissions is still high. Reference [97] improves end-to-end delivery and reduces broadcast storm problems, but the calculation for each vehicle may create computation overhead. Reference [73] reduces broadcast storm problem with less collision and more reachability, and [92] also targeted broadcast storm problem with the less disconnected network, at the cost of computation complexity and delay due to additional wait time, respectively.…”
