“…In this subsection, we review protocols proposed to date for the Tactile Internet. These protocols include a migration protocol over MEC [108], a handoff protocol [109] and a haptic handshake scheme for orchestrating heterogeneous tactile devices [110]. The reader should note that no protocol has been proposed so far by the IEEE P1918.1 standard, although interfaces have been identified [3].…”

The Internet has made several giant leaps over the years, from a fixed to a mobile Internet, then to the Internet of Things, and now to a Tactile Internet. The Tactile Internet goes far beyond data, audio and video delivery over fixed and mobile networks, and even beyond allowing communication and collaboration among things. It is expected to enable haptic communications and allow skill set delivery over networks. Some examples of potential applications are telesurgery, vehicle fleets, augmented reality and industrial process automation. Several papers already cover many of the Tactile Internet-related concepts and technologies, such as haptic codecs, applications, and supporting technologies. However, none of them offers a comprehensive survey of the Tactile Internet, including its architectures and algorithms. Furthermore, none of them provides a systematic and critical review of the existing solutions. To address these lacunae, we provide a comprehensive survey of the architectures and algorithms proposed to date for the Tactile Internet. In addition, we critically review them using a well-defined set of requirements and discuss some of the lessons learned as well as the most promising research directions.

“…Reference [23] considers the Long Term Evolution (LTE) mobile communication technologies to support vehicular applications. Reference [24] proposes a novel vertical handover protocol for seamless switching between IEEE 802.11p and LTE networks. However, these proposals do not consider the influence of handover from the view of the transport layer.…”

With the arrival of 5G, the wireless network will be provided with abundant spectrum resources, massive data transmissions and low latency communications, which makes Vehicle-to-Everything applications possible. However, VANETs always accompany with frequent network topology changes due to the highly mobile feature of vehicles. As a result, the network performance will be affected by the frequent handover. In this paper, a seamless handover scheme is proposed where the Software-Defined Networking (SDN) and Mobile Edge Computing (MEC) technologies are employed to adapt to the dynamic topology change in VANETs. The introduction of SDN provides a global view of network topology and centralized control, which enables a stable transmission layer connection when a handover takes place, so that the upper layer performance is not influenced by the network changes. By employing MEC server, the data are cached in advance before a handover happens, so that the vehicle can restore normal communication faster. In order to confirm the superiority of our proposal, computer simulations are conducted from different aspects. The results show that our proposal can significantly improve the network performance when a handover happens.

“…Du et al proposed a vertical handover protocol between LTE and 802.11p networks by considering number of vehicles, end-to-end distance and fixed nodes' speed. Nevertheless, for a reliable handover performance, it is necessary to apply various vehicle speeds under several traffic movement scenarios [1].…”

“…The next generation of wireless communication technologies, especially vehicular ad hoc networks are facing many challenges that need to be solved in order to be able to coexist with each other [1]. Seamless mobility is one of the challenges that needs to be addressed in order to provide the ability of uninterrupted inter-technology roaming for mobile nodes [2].…”

One of the most important factors to implement VANET is by considering the variety of wireless networks available around the city as well as the vehicles traffic scenarios. However, by providing a diverse range of wireless access technologies, it is necessary to provide continuous network connectivity as well as selecting the most suitable network technology and performance. Many researchers have worked on building algorithms for selecting the best network to improve the handover process. However, with high-speed vehicles mobility, the vertical handover process became the most challenging task in order to achieve realtime network selection. This paper proposes a bio-inspired network selection algorithm influenced by insect's behaviour which combines Artificial Bee Colony (ABC) and Particle Swarm Optimization (PSO). The proposed algorithm is applied to process multi-criteria parameters to evaluate the best available network and then execute the handover process seamlessly. The results demonstrate the benefits of the proposed Multi-Criteria ABC-PSO method by reducing the handover decision delays by 25%. It gives the optimum performance in terms of network selections and reduces the handover latency by 14.5%. The proposed algorithm also reduces the number of unnecessary handovers by 48% for three different mobility scenarios based on traffic environments (highway, urban and traffic jam).2 selecting the best among them. Hence, the concept of mobility in a heterogeneous wireless network implies the continuation of data transmission or maintaining an ongoing session while the point of attachment changes during VHO. The VHO happens when a Mobile Node (MN) roams between different networks and change the device interface (physical layer) which leads to different direction of data session in the user side as well as the network attachment point in the network side (network layer).Our proposed schemes present a multi-criteria artificial bee colony hybrid with particle swarm optimisation algorithm for evaluating the information gathered from the mobile nodes in the handover. The algorithm will process and calculate the required handover timing for each node in advance, based on the mobile nodes' velocity and received signal strength to reduce the handover process latency. The information is used to support all vertical handover operations, which includes network discovery, handover decision, and handover implementation.In the initial stage of the operation, the previous Access Point (AP) provides information about the neighbouring networks for the MN to quickly discover available networks. The second stage of the operation is selecting the best available network for the MN by considering its velocity and distance. The final operation of the proposed scheme involves the mobile node sharing the current information with its neighbouring nodes based on its current location. The schemes run on realtime simulation based on three mobility scenarios in city environment which are highway, urban and traffic jam scenario.
