“…Synchronized transmissions and additional overhead required for cluster formation and maintenance are the drawbacks of this scheme. To consider both channel quality and transmission distance in selecting the next relay node, Slavik and Maghoub [22] assign a shorter waiting time to vehicles belonging to a connected dominating set (CDS) and employs acknowledgements for every multi-hop message. The main disadvantage of the scheme is the piggy-backed acknowledgement that is sent as part of the periodic safety message, increasing its transmission overhead.…”

Multi-hop broadcast transmission is used in vehicular ad hoc networks (VANETs) to alert all vehicles within a geographical area of an emergency situation. However, the successful dissemination of multi-hop warning messages beyond the transmission range of a vehicle faces three major issues: (i) the broadcast storm, (ii) the severe interference with the existing periodic single-hop safety messages, and (iii) the hidden nodes. In this paper, we propose an efficient time-slotted multi-hop broadcast protocol that significantly reduces the number of required transmissions, while ensuring a timely and successful delivery of the warning messages. To alleviate the broadcast storm problem, we select only a subset of vehicles on the road to serve as the potential relay nodes. Each of these 'segment leaders' is responsible for forwarding the warning messages arrived in its own road segment. To avoid interfering with the safety messages transmitted periodically, we propose to allocate separate time slots for the warning messages. We also devise a signaling mechanism that ensures the reliable delivery of these multi-hop messages. Simulation results confirm that the developed protocol substantially outperforms existing schemes in terms of the number of required multi-hop transmissions and the dissemination delay. At the same time, the proposed solution maintains a high reception rate and low end-to-end delay for the single-hop safety messages.

“…VANET architecture relies on the information exchange via inter-vehicle communication to provide vehicles with a neighborhood view for safety purposes as well as other traffic management applications [1,2]. In an emergency situation (e.g., the sudden braking of a vehicle), an event-driven warning message is issued which can also be propagated over a long distance using multi-hop packet transmission strategies [3][4][5]. For active safety applications such as collision ✩ This work is supported in part by The University of Newcastle, Australia through an International Postgraduate Research Scholarship and an Early Career Researcher Grant G1301282.…”

“…Furthermore, many VANET transmission protocols are proposed, such as the adaptive connectivity aware routing (ACAR) [22], the urban vehicular broadcast (UVCAST) [23], the distribution-adaptive distance with channel quality (DADCQ) protocol for multi-hop broadcasting [24], etc. Those VANET technologies can be utilized to realize the communication between vehicles.…”

A protocol, called common driving notification protocol (CDNP), is proposed based on the classified driving behavior for intelligent autonomous vehicles, and it defines a standard with common messages and format for vehicles. The common standard format and definitions of CDNP packet make the autonomous vehicles have a common language to exchange more detail driving decision information of various driving situations, decrease the identification time for one vehicle to identify the driving decisions of other vehicles before or after those driving decisions are performed. The simulation tools, including NS-3 and SUMO, are used to simulate the wireless data packet transmission and the vehicle mobility; the experiment results present that the proposed protocol, CDNP, can increase the reaction preparing time with maximum value 250 seconds, decrease the identification time and the average travel time. Prospectively, it is decided to implement the CDNP as a protocol stack in the Linux kernel to provide the basic protocol capability for real world transmission testing.
