An effective handover management based on SINR and software‐defined network over urban vehicular ad hoc networks

Urban vehicular ad hoc network (UVANET) is a modality of high-topology variation MANET where vehicles travel across constrained layout of the roads and tall buildings, which eventually results in shadowing effects. One of the critical challenges in UVANET is the handover process that happens when a vehicle changes its association with the roadside unit. Urban area suffers from high vehicular density at traffic signals, and vehicle slowdowns caused by speed limits, frequent link disconnection caused by signal attenuation due to obstacles.Thus, it is difficult for UVANET to disseminate the packets to their destinations located in a specified area. This paper presents an effective handover management that calculates the signal-to-interference-plus-noise ratio (SINR) to ultimately determine the optimal cluster head for seamless handover in UVANET. It also utilizes the software-defined network to resolve the problem of handover failure in UVANET. The finding in the experimental results shows that the developed association clustering mechanism based on SINR significantly outperforms the baseline association mechanism. More importantly, it can resolve different types of handover problems that improved the quality of service in terms of throughput, handover latency, packet loss ratio, and handover failure ratio, when compared to the baseline handover mechanisms.

Essentially, the communication in UVANET based on software-defined network (SDN) can be classified into two main types: vehicle-to-vehicle (V2V) and vehicle-to-roadside unit (V2R). 4,5The controller base station has the role of SDN controller, which can guide the vehicles to make handover decisions based on several metrics such as vehicles speed and direction, location of vehicles, received signal strength indication (RSSI), and roadside unit (RSU) congestion. Handover in UVANET is a method to change the management of operative communication from one RSU to another. In seamless handover, the operative communication between vehicles should be continued while they are mobile from one RSU to another without perceptible latency. Many literature research studies proposed various solutions for handover in UVANET; however, they did not revoke the crucial difficulties of handover including quality of connection reduction and degradation of the QoS performance of the UVANET. Moreover, the characteristic of UVANET can cause enormous types of unnecessary handovers, which consumes more energy in order to control traffic congestion and this eventually leads to handover failure. The most crucial problems that cause handover failure in UVANET primarily includes mobility, communications jamming and interference, coverage hole, and data traffic congesti...

Vehicular ad hoc network (VANET) is a style of high‐mobility mobile ad hoc network where the mobile nodes are vehicles traveling across a road or a street. VANET was proposed to provide safety, comfortability, reliability, and security of vehicles driving. One of the serious challenges is handover (HO) problem that occurs when a vehicle moves from one network area covered by a roadside unit (RSU) to another network area covered by a different RSU. The fast mobility of vehicles and the limited coverage area of the RSU (without overlapping signals) should be considered in providing a seamless HO. This paper presents a comprehensive survey on HO management for VANET based on the new features of fifth‐generation (5G) mobile network technologies. The 5G mobile network technology provides enhanced characteristics that will fit the requirements of real‐time video streaming and assist to design an effective solution for the HO problem. In addition, this paper presents the reasons for HO failures and the limitations of available HO failure solutions. Furthermore, it highlights the potential proposed solutions that will tackle the HO failures. This survey will open up the gate of developing an optimal solution based on 5G for HO problem on VANET that might be used in vehicles manufacturing.

SDN/NFV‐based handover management approach for ultradense 5G mobile networks

With the great increase of connected devices and new types of applications, mobile networks are witnessing exponential growth of traffic volume. To meet emerging requirements, it is widely agreed that the fifth-generation mobile network will be ultradense and heterogeneous. However, the deployment of a high number of small cells in such networks poses challenges for the mobility management, including frequent, undesired, and ping-pong handovers, not to mention issues related to increased delay and failure of the handover process.The adoption of software-defined networking (SDN) and network function virtualization (NFV) technologies into 5G networks offers a new way to address the above-mentioned challenges. These technologies offer tools and mechanisms to make networks flexible, programmable, and more manageable. The SDN has global network control ability so that various functions such as the handover control can be implemented in the SDN architecture to manage the handover efficiently. In this article, we propose a Software-Defined Handover (SDHO) solution to optimize the handover in future 5G networks. In particular, we design a Software-Defined Handover Management Engine (SDHME) to handle the handover control mechanism in 5G ultradense networks. The SDHME is defined in the application plane of the SDN architecture, executed by the control plane to orchestrate the data plane. Simulation results demonstrate that, compared with the conventional LTE handover strategy, the proposed approach significantly reduces the handover failure ratio and handover delay. KEYWORDS 5G ultradense networks, fast handover, network function virtualization, software-defined networking, virtual cell Int J Commun Syst. 2019;32:e3831. wileyonlinelibrary.com/journal/dac FIGURE 1 Topology of ultradense network (UDN) toward 5G. SDN, software-defined networkingexperience. The topology of UDN toward 5G is illustrated in Figure 1. In UDN, a high number of point of attachment (PoA) are distributed randomly without network planning. 3 The next-generation network is characterized by heterogeneous networks having different coverage ranges such as picocell, femtocell, attocell, and multiple radio access technologies (RATs) such as 4G, 5G, and WLAN. In this way, a greater number of simultaneous device connections are enabled by the ultradense heterogeneous small cells.Although UDN helps to solve coverage, capacity, spectrum efficiency, and data rates problems on the access side, it issues many challenges to the mobility management such as handover problems faced by mobile users and poor performance like long handover delay, failures, and increased signaling overhead. This causes disconnection and quality of service (QoS) degradation. Accordingly, ultradense 5G mobile networks require innovations in the management of the network and necessitate a novel and accurate handover management mechanism to deal with these challenges. Recently, the 3rd Generation Partnership Project (3GPP) organization has focused on software-defined networking (SDN) and netwo...
