“…The communication is divided between two types of vehicles, where primary vehicles take on the role as a gateway of information from 3G/4G cellular network, while secondary vehicles exchange information via IEEE 802.11b-based ad hoc network. In [32] and [33], authors assumed in-vehicle OBUs with multiple interfaces and proposed LTE technology assisted cluster-head selection and management protocols for the IEEE 802.11p-based VANETs. Karsaros et al [34] proposed heterogeneous architecture for location service which offloads the location service control traffic over the infrastructure-based LTE cellular networks while utilizing IEEE 802.11p ad hoc network for transferring data traffic.…”

Various wireless communication systems exist, which enable a wide range of applications and use cases in the vehicular environment. These applications can be grouped into three types, namely, road safety, traffic efficiency, and infotainment, each with its own set of functional and performance requirements. In pursuance of assisting drivers to travel safely and comfortably, several of these requirements have to be met simultaneously. While the coexistence of multiple radio access technologies brings immense opportunities towards meeting most of the vehicular networking application requirements, it is equally important and challenging to identify the strength and weaknesses of each technology and understand which technology is more suitable for the given networking scenario. In this paper, we evaluate two of the most viable communication standards, Institute of Electrical and Electronics Engineers (IEEE) 802.11p and long-term evolution (LTE) by 3rd Generation Partnership Project for vehicular networking. A detailed performance evaluation study of the standards is given for a variety of parameter settings such as beacon transmission frequency, vehicle density, and vehicle average speed. Both standards are compared in terms of delay, reliability, scalability, and mobility support in the context of various application requirements. Furthermore, through extensive simulation-based study, we validated the effectiveness of both standards to handle different application requirements and share insight for further research directions. The results indicate that IEEE 802.11p offers acceptable performance for sparse network topologies with limited mobility support. On the other hand, LTE meets most of the application requirements in terms of reliability, scalability, and mobility support; however, it is challenging to obtain stringent delay requirements in the presence of higher cellular network traffic load.

This paper presents a new clustering mechanism for the multi-hop relay in vehicular communication. In the proposed mechanism, the cluster-head selection is implemented using the enhanced hybrid wireless mesh protocol (E-HWMP) protocol, which is based on the IEEE802.11p and IEEE802.11s standards. Then, multi-hop routing is designed for VANET in Wireless Mesh Networks (WMNs). Therefore, the main aim of this study is to enhance the integration of VANET with a cellular network (i.e., LTE). As a result, the coverage can be extended. The proposed E-HWMP mechanism is evaluated by the NS2 simulator, and the VanetMobiSim is used as a mobility generator. The proposed E-HWMP mechanism is compared to the existing mechanism based on the packet's delivery ratio, packet loss, throughput, overhead, and average end-to-end delay. The results demonstrate that the proposed E-HWMP mechanism outperforms the existing clustering mechanism.

“…Manoharan et al [3] proposes a multi-metric gateway selection mechanism that selects an optimal gateway from the dual-interface-enabled gateway candidates. Sivaraj et al [4] presents a heterogeneous architecture of combining 802.11p and LTE. Mangel et al [5] analyzes the suitability of UMTS and LTE for cross-traffic assistance in the worst case with respective to load and latency requirements and the results show that UMTS suffers from capacity limitations while LTE could work well.…”
