Internet of Vehicles (IoV) is developed by integrating the intelligent transportation system (ITS) and the Internet of Things (IoT). The goal of IoV is to allow vehicles to communicate with other vehicles, humans, pedestrians, roadside units, and other infrastructures. Two potential technologies of V2X communication are dedicated short-range communication (DSRC) and cellular network technologies. Each of these has its benefits and limitations. DSRC has low latency but it limits coverage area and lacks spectrum availability. Whereas 4G LTE offers high bandwidth, wider cell coverage range, but the drawback is its high transmission time intervals. 5G offers enormous benefits to the present wireless communication technology by providing higher data rates and very low latencies for transmissions but is prone to blockages because of its inability to penetrate through the objects. Hence, considering the above issues, single technology will not fully accommodate the V2X requirements which subsequently jeopardize the effectiveness of safety applications. Therefore, for efficient V2X communication, it is required to interwork with DSRC and cellular network technologies. One open research challenge that has gained the attention of the research community over the past few years is the appropriate selection of networks for handover in a heterogeneous IoV environment. Existing solutions have addressed the issues related to handover and network selection but they have failed to address the need for handover while selecting the network. Previous studies have only mentioned that the network is being selected directly for handover or it was connected to the available radio access. Due to this, the occurrence of handover had to take place frequently. Hence, in this research, the integration of DSRC, LTE, and mmWave 5G is incorporated with handover decision, network selection, and routing algorithms. The handover decision is to ensure whether there is a need for vertical handover by using a dynamic Q-learning algorithm. Then, the network selection is based on a fuzzy-convolution neural network that creates fuzzy rules from signal strength, distance, vehicle density, data type, and line of sight. V2V chain routing is proposed to select V2V pairs using a jellyfish optimization algorithm that takes into account the channel, vehicle characteristics, and transmission metrics. This system is developed in an OMNeT++ simulator and the performances are evaluated in terms of mean handover, handover failure, mean throughput, delay, and packet loss.

Internet of vehicles (IoV) is an emerging area that gives support for vehicles via internet assisted communication. IoV with 5G provides ubiquitous connectivity due to the participation of more than one radio access network. The mobility of vehicles demands to make handover in such heterogeneous network. The vehicles at short range uses dedicated short range communication (DSRC), while it has to use better technology for long range and any type of traffic. Usually, the previous work will directly select the network for handover or it connects with available radio access. Due to this, the occurrence of handover takes place frequently.  In this paper, the integration of DSRC, LTE and mmWave 5G on IoV is incorporated with novel handover decision making, network selection and routing. The handover decision is to ensure whether there is a need for vertical handover by using Dynamic Q-learning algorithm that uses entropy function for threshold prediction as per the current characteristics of the environment. Then the network selection is based on fuzzy-convolution neural network (F-CNN) that creates fuzzy rules from signal strength, distance, vehicle density, data type and line of sight. V2V chain routing is proposed to select V2V pairs using jellyfish optimization algorithm (JOA) that takes in account of channel, vehicle and transmission metrics. This system is developed in OMNeT++ simulator and the performances are evaluated in terms of success probability, handover failure, unnecessary handover, mean throughput, delay and packet loss.

Recent Years compared to the Current Scenario, The Explosive Growth of devices connected and controlled by Internet is the major significance of Internet of Things (IOT). One such big example is Automotive Industry. This industry has the potential to become an IOT Champion among other industries and fuel the IOT Cloud Services Adoption among Car owners and walkers alike. Vehicles are progressively being associated with the Internet of Things which empower them to give Universal Access to Data to Drivers and Travellers while Moving. As the connectivity of Vehicles keeps increasing in numbers,traditional concepts of Vehicles has to be introduced with new layers which includes Versatile data transfer among Vehicles, Consistency, Security, Toughness, Humans and roadside frameworks of Vehicular Systems shall be taken into consideration. In this Unique situation, the first idea of Vehicular Ad-Hoc networks(VANETs) is being changed into another idea called Internet of Vehicles(IOV).The advent of IOT has changed the Traditional vehicular networks in to intelligent vehicular networks called Internet of vehicles. Each entity in IOV is connected to the Internet. In IOV, each vehicle is responsible for transmitting and receiving the information. In an Environment where vehicles are mobile and at the same time exchanging information to ensure safe driving on the roads and to minimize road accidents. It is very necessary to provide better services within the limited accessibilities. Hence QOS plays a vital role in IOV.This paper addresses the QOS challenges and its significance in IOV. Also, this paper also discusses the measurement parameters that could deliberately effect the performance of IOV.
