“…In [15], a handover decision was made using velocity, network geometry, and received signal strength indication (RSSI). Authors in [16] highlighted that user-based location played a vital role in decision making and maintained a database that improved the failure rate of handover decision making. In another work [17], delay, bandwidth, and jitter are considered for handover decision making.…”

The real-time monitoring and autonomous decision making through unmanned aerial vehicles (UAVs) are the potential applications of future networks. Vertical handover in future networks is a mechanism to switch communication between different network access technologies like Wireless Local Area Network (WLAN), Worldwide Interoperability for Wireless Microwave Access (WiMAX), Third-Generation (3G), Fourth-Generation (4G), and Fifth-Generation (5G) mobile technologies. These technologies have significant importance in providing fast, reliable, and timely communication. However, during a vertical handover, an inadequate delay and packet loss can cause considerable disruption in maintaining communication sessions and results in intolerable end-to-end delay, disconnectivity, and poor packet delivery ratio. The proposed work addresses the vertical handover method in UAVs communication by designing a relay-based vertical handover technique. The relay UAVs is an assistant node, requiring an organized and intelligent deployment that assists in vertical handover and communication by minimizing the average packet loss and average delay from source to destination. Moreover, a multicriteria handover parameter triggering is used for seamless and more extended network coverage. Extensive simulations using S-shaped and U-shaped trajectories are designed and simulated for relay-based vertical handover performance evaluation. The results obtained show that our proposed relay-based handover method offers seamless connectivity and high-performance experienced during the vertical handover process. The extensive comparison with state-of-the-art techniques proves that the proposed method is better in terms of 18% handover success rate, 21% end-to-end delay, and 29% packet loss.

“…Furthermore, this type of HO scheme is usually combined with other HO decision factors, such as the RSS, UE's direction factor, and type of mobile data traffic, as in [30] and [31]. In addition, HO based on mobile speed is typically used in high-speed mobile scenarios, such as in vehicular networks or High-Speed Rail (HSR) [32], [33].…”

Handover (HO) management is essential in mobile cellular networks. It ensures seamless connectivity to the User Equipment (UE) while moving from one Base Station (BS) to another within the coverage area. HO optimization refers to the adoption of intelligent and automatic HO techniques in mobile networks. HO optimization is gaining more importance in Fifth-Generation (5G) and Beyond (B5G) systems because of the requirements and specifications that B5G targets. The requirements of B5G include global connectivity, ultra-low latency, big data analytics, extreme data rate transmissions, a massive number of devices in a small area, and new technologies that will support the B5G network, such as Millimeter Wave (mmWave), Terahertz (THz) communication, and Ultra-Dense Networks (UDNs). All these factors cause new HO optimization challenges and require new solutions for HO optimization techniques. This study comprehensively provides HO optimization challenges and solutions in B5G. First, it provides a research background and explanation of HO in legacy. It then investigates the HO optimization challenges in B5G, including future research directions. The paper then discusses the most prominent and recent techniques and technological solutions for HO optimization management in B5G. Finally, we highlight potential techniques for HO optimization in B5G.

“…The authors of [15] suggest the use of a smart mobility pattern recognition handover, known as Smart-HO. A fast handover procedure that calculates the weight of the neighboring cells depending on the location and the speed of the train is discussed in [16]. A 5G dual handover strategy based on concurrent horizontal and vertical handovers using two antennas installed on the train, called multi Radio-Access-Technology (multi-RAT) is presented [17].…”

The cellular users, on high speed railways and highways, travel at a very high speed and follow a nearly straight path, in general. Thus, they typically undergo a maximum frequency of handovers in the cellular environment. This requires a very fast triggering of the handover. In the existing method of handover in 5G cellular communication, for high speed users, neither the decision-making of handover nor the triggering of handover is sufficiently fast. This can lead to poor signal quality and packet losses and in the worst case, radio link failure (RLF) during a handover. This paper proposes a forward handover based method, combined with PN sequence detections, to facilitate a quicker handover for high speed users on railways and highways. The proposed method adds some complexity but can offer a significant improvement in the overall handover delay. A simplistic simulation is used to demonstrate the improvement of the proposed method.
