“…From the last few years, many challenges have to face by ad hoc network due to unbounded size in the network and high mobility. To the best of our knowledge, the framework size, the mobility of the nodes is very high and unbounded size of geographical area of the network; it is not that easy to network connectivity between the vehicle nodes [4] [5].In the previous years, the work done in this network isBased on the single stack layer it creates many difficulties in front of traffic management [6]. Network Layer has only responsibility to transmit the information from source to destination it helps to improve the services of the network but that improvement is not enough still networks face many problems in his Network, the speed of the nodes (vehicles) is not Calculated and sometimes due to very high speed of nodes, network is not able to catch the information the Internet of the vehicles was being a fa s c i n a t i n g concept.…”

The vehicular ad-hoc networks (VANETs) are specific type or a sub form of Mobile ad hoc networks (MANETs). However the main problem which is related to this network is the Quality of Service (QoS) which mainly occurs due to rapid change topology nature in the network and lack of stability of communication. Consequently, some of the challenges that researcher focus on routing protocols for VANET. The problem which is faced by this network with these protocols is the dynamic environment in their route instability. This paper approaches the combination of Dynamic Source Routing protocol (DSR) and Particle Swarm Optimization Algorithm (PSO) to solve the problems of Routing protocols which help to improve the Quality of service (QoS) in the network. The approach which is introduced in this paper is to make use for making the better Quality of Service (QoS) in the VANET. The simulation results in MATLAB exactly predict the overall performances regarding the proposed work in terms of the packet drop ratio, transmission delay, channel utilization, Throughput and Energy consumption under varying conditions

“…In this paper, we consider two important aspects of a vehicular network [ 8 ]: one regards handover issues for guaranteeing service continuity to vehicles inside the considered area taking into account also the Road Side Unit (RSU) load balancing and the other aims to provide a mechanism able to avoid collision among vehicles. Both considered aspects are based on the use of the MEC paradigm [ 9 ] in order to consider a critical point in VANET environment: the latency.…”

In this paper, some collision avoidance systems based on MEC in a VANET environment are proposed and investigated. Micro services at edge are considered to support service continuity in vehicle communication and advertising. This considered system makes use of cloud and edge computing, allowing to switch communication from edge to cloud server and vice versa when possible, trying to guarantee the required constraints and balancing the communication among the servers. Simulation results were used to evaluate the performance of three considered mechanisms: the first one considering only edge with load balancing, the second one using edge/cloud switching and the third one using edge with load balancing and collision avoidance advertising.

“…Today the navigation systems are considered an integrated part of the Intelligent Transportation System (ITS) and Vehicular Ad-Hoc Network (VANET) system [ 5 ]. The vehicles are equipped with GPS receivers and, in the next future, all vehicles will have a GNSS receiver on board [ 6 , 7 ].…”

Vehicle positioning is becoming an important issue related to Intelligent Transportation Systems (ITSs). Novel vehicles and autonomous vehicles need to be localized under different weather conditions and it is important to have a reliable positioning system to track vehicles. Satellite navigation systems can be a key technology in providing global coverage and providing localization services through many satellite constellations such as GPS, GLONASS, Galileo and so forth. However, the modeling of positioning and localization systems under different weather conditions is not a trivial objective especially considering different factors such as receiver sensitivity, dynamic weather conditions, propagation delay and so forth. This paper focuses on the use of simulators for performing different kinds of tests on Global Navigation Satellite System (GNSS) systems in order to reduce the cost of the positioning testing under different techniques or models. Simulation driven approach, combined with some specific hardware equipment such as receivers and transmitters can characterize a more realistic scenario and the simulation can consider other aspects that could be complex to really test. In this work, the main contribution is the introduction of the Troposphere Collins model in a GNSS simulator for VANET applications, the GPS-SDR-SIM software. The use of the Collins model in the simulator allows to improve the accuracy of the simulation experiments throughout the reduction of the receiver errors.
