“…Simulation results show an improved performance for the proposed protocol for both the sparse and dense VANET environments. In [37], authors present detailed architecture of a cross layer based routing scheme for cooperative VANETs. The authors present a cross layer solution that makes routing decisions based on link capacity and adjusting the probability of connectivity at MAC layer accordingly.…”

In recent years, vehicular ad-hoc networks have emerged as a key wireless technology offering countless new services and applications for the transport community. Along with many interesting and useful applications, there have been a number of design challenges to create an efficient and reliable routing scheme. A conventional design approach only optimizes routing schemes without considering the constraints from other network layers. This may result in an under-performing routing mechanism. In this paper we present the design of a multi-hop cross-layer routing scheme that utilises beaconing information at the physical layer as well as queue buffer information at medium access control layer to optimise routing objectives. In particular, the proposed scheme integrates channel quality information and queuing information from other layers to transmit data. Using simulations as well as analytical studies we have presented results of our proposed scheme and have done a thorough comparison with existing approaches in this area. The results highlight better performance of the proposed cross-layer structure as compared to other conventional single layer approaches.

“…Among these research Zhou et al (2008) proposed a cross layer cooperative VANET with rate and medium access control, they introduced cooperative communication and cross layer link detection at the MAC, network and transport level in order to improve message dissemination and fairness of medium access. However, this system employs the use of roadside units or "gateways" to achieve this aim, this will no doubt add to the overall cost of the VANET architecture and reliance on extra hardware should as much as possible be minimised.…”

Vehicular ad-hoc network (VANET) has quickly become an important aspect of the intelligent transport system (ITS), which is a combination of information technology, and transport works to improve efficiency and safety through data gathering and dissemination. However, transmitting data over an ad-hoc network comes with several issues such as broadcast storms, hidden terminal problems and unreliability; these greatly reduce the efficiency of the network and hence the purpose for which it was developed. We therefore propose a system of utilising information gathered externally from the node or through the various layers of the network into the access layer of the ETSI communication stack for routing to improve the overall efficiency of data delivery, reduce hidden terminals and increase reliability. We divide route into segments and design a set of metric system to select a controlling node as well as procedure for data transfer. Furthermore we propose a system for faster data delivery based on priority of data and density of nodes from route information while developing a map to show the communication situation of an area. These metrics and algorithms will be simulated in further research using the NS-3 environment to demonstrate the effectiveness.

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.
