“…Regarding vehicular environments, adaptive schemes are able to adapt the dissemination policy to the specific conditions of the scenario, thereby improving the dissemination process, or reducing the channel contention. In this section we compare the performance of our proposal against other existing adaptive dis-semination schemes: DV-CAST (Tonguz et al, 2010), UV-CAST (Viriyasitavat et al, 2011), and FDPD (Sormani et al, 2006). …”

Efficient message dissemination is of utmost importance to propel the development of useful services and applications in Vehicular ad hoc Networks (VANETs).In this paper, we propose a novel adaptive system that allows each vehicle to automatically adopt the optimal dissemination scheme in order to fit the warning message delivery policy to each specific situation. Our mechanism uses as input parameters the vehicular density and the topological characteristics of the environment where the vehicles are located, in order to decide which dissemination scheme to use. We compare our proposal with respect to two static dissemination schemes (eMDR and NJL), and three adaptive dissemination systems (UV-CAST, FDPD, and DV-CAST). Simulation results demonstrate that our approach significantly improves upon these solutions, being able to support more efficient warning message dissemination in all situations ranging from low densities with complex maps, to high densities in simple scenarios. In particular, RTAD improves existing approaches in terms of percentage of vehicles informed, while significantly reducing the number of messages sent, thus mitigating broadcast storms.

“…However, since such information requires excessive information exchange between vehicles which is not desirable in VANETs, we use a distributed gift-wrapping algorithm first proposed in [8]. This algorithm is a distributed algorithm; a vehicle, upon receiving a message, can determine independently and in a distributed manner whether it lies on the boundary of the coverage polygon.…”

“…Note that since it only relies on the local information, the distributed gift-wrapping algorithm is only an approximate algorithm and it tends to over-select boundary vehicles (i.e., some vehicles selected by the algorithms may not lie on the boundary of the polygon). More details about this algorithm can be found in [8]. In addition to the giftwrapping algorithm, additional rules that consider directions of vehicles are added to the original distributed gift-wrapping algorithm; i.e., only vehicles that travel toward the scene of accidents act as temporary RSUs.…”

Abstract-The gradual penetration of Dedicated Short Range Communications Radio (DSRC) technology in the years to come is a formidable problem that could adversely effect the implementation of safety and non-safety applications. In this paper, we propose a solution that might mitigate the negative impact of the partial and gradual penetration problem of DSRC technology. The proposed solution is based on a self-organizing network paradigm that draws its inspiration from biological systems, such as social insect colonies [1]. By designing the local rules and a distributed algorithm needed to perform this function, it is shown that DSRC-equipped cars can indeed serve as RSUs. Results show that the message reachability and connectivity in urban vehicular networks can be increased substantially in a cost-effective manner as the proposed approach does not entail deployment of infrastructure-based RSUs.

“…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.
