“…Besides the low granularity of this dataset, the information is gathered from sensors placed along the highway. In our case, the dataset was gathered from the vehicle itself, enabling analysis of real mobility patterns, taking advantage of V2V and V2I communications in urban and parking lot scenarios [4].…”

“…A vehicular network emulator, entitled mOVERS [4], developed in Institute of Telecommunications (IT), Aveiro, was the platform used in the evaluation of the content distribution strategies. This emulator runs a Delay-Tolerant Network (DTN), which allows the creation of multiple processes that run DTN software, and is capable of scaling for larger networks with the same software as the one that is running in the OBUs/RSUs in the real Oporto vehicular network [1].…”

“…The mOVERS is the opportunistic DTN-based architecture called mOVE (mobile Opportunistic VEhicular) [4] adapted to work as an emulator. mOVE is a highly modular and extensible architecture implemented in C++ and it supports standard IEEE 8012.11p, WAVE protocols, IEEE 802.11a/b/g, and WiFi technology at the same time.…”

“…Three dissemination strategies are implemented and evaluated in different scenarios, e.g., city center and parking lot, and they include: (1) a strategy that replicates the content that has traversed the least number of hops, LNHF; (2) a strategy that replicates the rarest content in the vehicle's neighborhood, LRBF; and (3) a strategy that combines the concept of network coding and content distribution, replicating the rarest code generation in the vehicle's neighborhood, LRGF. To support this realistic study, we use mOVERS [4], an emulator capable of recreating scalable vehicular scenarios of content distribution in vehicular networks, which replicates the same software of the vehicular On-Board Units (OBUs), and integrates real vehicular network data such as mobility of vehicles and connectivity. This emulator works with mOVE (mobile Opportunistic VEhicular) DTN platform, and it contains a base opportunistic approach for data dissemination that can be used to develop, test and evaluate routing mechanisms and data delivery strategies for both data gathering through vehicles, and content distribution strategies from the infrastructure to the vehicles, using vehicles as content delivery nodes.…”

The main drivers for the continuous development of Vehicular ad-hoc Networks (VANETs) are safety applications and services. However, in recent years, new interests have emerged regarding the introduction of new applications and services for non-urgent content (e.g., videos, ads, sensing and touristic information) dissemination. However, there is a lack of real studies considering content dissemination strategies to understand when and to whom the content should be disseminated using real vehicular traces gathered from real vehicular networks. This work presents a realistic study of strategies for dissemination of non-urgent content with the main goal of improving content delivery as well as minimizing network congestion and resource usage. First, we perform an exhaustive network characterization. Then, several content strategies are specified and evaluated in different scenarios (city center and parking lot). All the obtained results show that there are two content distribution strategies that clearly set themselves apart due to their superior performance: Local Rarest Bundle First and Local Rarest Generation First.

“…There are several simulators for networking, and for robotics. Pessoa et al [ 23 ] presented mOVERS, an emulator capable of recreating scalable vehicular scenarios of data gathering and content distribution in vehicular networks. This emulator works with mobile Opportunistic VEhicular (mOVE), a DTN-based architecture supporting communications using IEEE 802.11p and Wireless Access in Vehicular Environments (WAVE), and IEEE 802.11a/b/g (Wi-Fi technology) developed in the Network Architectures and Protocols research group , where each node is capable of storing a packet and forwards it when a neighbor is available.…”

The Smart City concept is starting to extend into maritime environments alongside with the increase of Unmanned Surface Vehicles (USV) models on the market. Consequently, by joining both Smart City and USV technologies, a set of platforms and applications for aquatic environments are emerging. This work proposes a low-cost aquatic mobile sensing platform for data gathering with a swarm of USVs communicating through a Delay-Tolerant Network (DTN). A set of DTN link quality-based routing strategies select the best quality path in a dynamic approach so the sensed information is able to reach the mobile gateway in a reliable way. A Link Quality Estimation (LQE) approach is proposed and its accuracy is evaluated through real experimentation. An aquatic simulation environment, considering both navigation and communication layers, was also proposed and used to evaluate the performance of the proposed routing strategies, and complement real environment performance studies.

Summary Nowadays, inter‐vehicle and intra‐vehicle communication triggers the development of safety and non‐safety applications in Vehicular Adhoc NETworks (VANET). These applications need to be evaluated before the actual implementation. The performance of these applications is generally evaluated through indispensable tools such as simulators, emulators, and testbeds. Although simulators, emulators, and testbeds are available as open‐source or proprietary for VANET applications, finding the correct tool for the experiment is intriguing and challenging from the researcher's perspective. In this paper, our focus is to provide a comprehensive survey on the existing simulators, emulators, and real time testbeds based on technical specifications, capabilities, etc. To the best of our knowledge, there is no such an exhaustive survey that exists in the literature. Further, we developed a real time low‐cost VANET testbed on our institute campus to implement the VANET related projects.
