“…Wu et al [27] used fuzzy logic algorithm to choose the best relay node by taking intervehicle distance, vehicle velocity, and link quality into account. To lower safety message transmission delay and reduce message redundancy, Bi et al [28] utilized iterative partition, mini-slot, and blackburst to quickly select forwarding node. Although these works are useful to improve the performance of safety messages propagation, they mainly focus on the design of broadcast protocol, so as to make safety messages be received by other relevance vehicles with low dissemination delay and high reliability.…”

Safety messages propagation is the major task for Vehicular Cyber-Physical Systems in order to improve the safety of roads and passengers. However, reducing traffic and car accidents can only be achieved by disseminating safety messages in a timely manner with high reliability. Although mathematical modeling of the delay of safety messages is extremely beneficial, analyzing the safety messages propagation is considerably complex due to the high dynamics of vehicles. Moreover, most previous works assume vehicles drive independently and the interaction between vehicles is not taken into consideration. In this paper, we proposed an analytical model to describe the performance of safety messages propagation in the VCPSs under platoon-based driving pattern. Infrastructure-less and RSU-supported scenarios are evaluated independently. The analytical model also takes into account different transmission situations and various system parameters, such as communication range, traffic flow, and platoon size. The effectiveness of the analytical model is verified through simulation and the impacts of different parameters on the expected transmission delay are investigated. The results will help determine the system design parameters to satisfy the delay requirement for safety applications in VCPSs.

“…Various mechanisms have been proposed to make up for 802.11p for the provision of reliable broadcasts [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. In [4][5][6][7][8] the authors proposed extensions of 802.11p to avoid the collisions caused by the hidden terminal.…”

“…On the other hand [9][10][11][12][13][14][15][16] proposed the acknowledgment schemes for 802.11p to check the reception of broadcast message at the target vehicles and to have the rebroadcast be made if it is needed in order to guarantee the reliable broadcast. In particular, [17][18][19] focus on the reliable broadcast in urban environments and address the problem of broadcast inefficiency in addition to the reliability. Broadcast efficiency is critical in urban environments where the traffic density is relatively high.…”

“…Differing from [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], [20,21] proposed reliable broadcast mechanisms for VANET to be implemented above the MAC layer, that is, 802.11p. Their common design objectives are to reduce the number of broadcast forwarding attempts by selecting vehicles that can forward the message to the largest possible number of vehicles that have not received the message yet to optimize the broadcast efficiency.…”

Safety services of Vehicular Ad Hoc Network (VANET) require reliable broadcasts. We propose a reliable broadcast mechanism for urban roads called VANET Broadcasting for Urban areas based on Road Layout (VBURL), which tries to minimize the dependency on information that may become inaccurate to maximize the efficiency of broadcast. Specifically, the proposed mechanism takes into account the road layout information accessible from the digital map and only the real-time information obtained from the broadcast messages or beacons. VBURL basically makes the vehicle that is farthest from the current forwarding vehicle take the role of next forwarding vehicle and, if possible, makes an additional broadcast happen at the intersections where the effect of signal attenuation caused by the road side obstacles is low in order to have prompt and reliable dissemination of safety messages towards all roads connected to the intersections. The simulation results verified that VBURL achieves the same high performance as that of the compared legacy schemes in terms of reliability with much higher efficiency. Even though the message reception delay of VBURL is slightly longer than those of compared schemes, it is far less significant to impair the original purpose of safety message.

“…The Base Station is further connected to the device that observes the entire system that can be a server/mainframe. This development has not only created an innovative prospect, but also raised number of challenges for the investigations in the sensor vehicles such as to support multi-hop communication when the constraint is being set up in radio operation for conserving the power, challenges in geographic routing, monitoring and preservation of dynamic, resource limited systems with the clarification of the challenge [8].…”

Abstract-VehicularAd hoc network is the most fast growing which shape fresh engineering opportunities like controlling traffic smartly, optimal resource maintenance and improved service for customers. Vehicular Ad hoc Network (VANET) is one of the most popular ad hoc networks. A vehicular ad hoc network generally faces the problems like trust modeling, congestion, and battery optimization issues. If the nodes are comparatively less than it can handle the traffic well when it comes to transferring the data at a rapid rate. But, when it comes to high-density traffic than a Vehicular network always faces congestion problem. This paper tried to find the reliable solution to the traffic management by adding up the virtual gears into the network and optimizes the congestion problem by using a trust queue which is updated with the broadcast concept of the hello packets in order to remove the unwanted nodes in the list. The network performance has been measured with QOS Parameters like delay, throughput, and other parameters to prove the authentication of the research.
