“…Hence, neither a transformation nor a cyclic-prefix is required, which reduces the computational complexity and necessary overhead. High node mobility, as prevelant in VANETs and FANETs [13], [14], causes frequent disconnections and topology changes. Common routing protocols rely on broadcasting topology control messages which limits the overall scalability [15].…”

Cooperative transmission is a promising approach to establish robust communication in Mobile Ad-Hoc Networks (MANETs). In low-complexity MANETs several transmitters (TX) can be aggregated to a virtual multiple input system. For such a setup, the impact of various timing and carrier frequency offsets (TO, CFO) has to be mitigated. We propose an effective, purely time-domain based equalizer structure that allows to establish cooperative transmission with a transmit diversity scheme in presence of aforementioned impairments and multipath channels. Exemplarily investigating the broadcast performance by outage simulations in a MANET scenario, we can demonstrate the benefits and indicate that the proposed structure is auspicious to improve the general scalability of MANETs.

“…Furthermore, the authors discuss the pros and cons of routing protocols in each branch and the associated challenges. Similarly, the authors of [13][14][15] have done extensive survey studies on many aspects of routing protocols in VANETs and the authors of [16,17] have mainly focused on routing for unmanned aerial vehicles.…”

The number of vehicles on the road increases daily, causing many fatal accidents and wasting much time for the average commuter every day due to congestion. Vehicular ad hoc networks (VANETs) were introduced to overcome these issues by enabling vehicle-to-vehicle communication and vehicle-to-infrastructure communication. The prime challenge in VANETs is the necessity of very low communication delays, especially for safety-related applications due to the high mobility nature of vehicles. The VANET architecture introduces a network component, the Road Side Unit (RSU), to meet the required delay limitations. Even though the RSU is a critical component in VANETs, as expected, the RSUs were not deployed throughout the world because of their high investment cost. As a solution, the idea of mobile RSU (mRSU) was introduced, and, ever since, several techniques of mRSU deployment strategies have been proposed. In this survey, we first analyze the importance of the RSU to the VANET architecture with real-world data incorporating the new 5G standard. Then, we investigate the research done in the areas of mRSU and exploit the pros and cons of each mRSU deployment strategy. Finally, we also discuss the future research directions of mRSU, and we explain the challenges connected to these future trends.

“…For the non-clustering-based approaches [40,41] an optimal routing scheme is used to enhance message overhead problems that occur in the traditional broadcasting process [42,43]. The idea consists of sending the message to a "forwarding vehicle" which broadcasts it to all its nearest neighbors (1hop) [44].…”

Nowadays, video streaming applications are becoming one of the tendencies driving vehicular network users. In this work, considering the unpredictable vehicle density, the unexpected acceleration or deceleration of the different vehicles included in the vehicular traffic load, and the limited radio range of the employed communication scheme, we introduce the "Dynamic Vehicular Clustering" (DVC) algorithm as a new scheme for video streaming systems over vehicular ad-hoc networks (VANET). The proposed algorithm takes advantage of the small cells concept and the introduction of wireless backhauls, inspired by the different features and the performance of the Long Term Evolution (LTE)-Advanced network. Vehicles are clustered together to form dynamically ad-hoc sub-networks included in the vehicular network. The goal of our clustering algorithm is to take into account several characteristics, such as the vehicle's position and acceleration to reduce latency and packet loss. Therefore, each cluster is counted as a small cell containing vehicular nodes and an access point that is elected regarding some particular specifications. Based on the exceptional features of the LTE-Advanced network (small cells and wireless backhauls) the DVC algorithm is a promising scheme for video streaming services over VANET systems. Experiments were carried out with a virtual topology of the VANET network created with four clusters to implement the DVC algorithm. The results were compared with other algorithms such as Virtual Trust-ability Data transmission (VTD), Named Data Networking (NDN), and Socially Aware Security Message Forwarding (SASMF). Our algorithm can effectively improve the transmission rate of data packets at the expense of a slight increase in end-to-end delay and control overhead.
