“…Very less literature is available on handover of D2D communication. A basic and effective handover algorithm is the handover decision method [28], involving the use of a number of variables referred to as, Handover Margin (HOM), Time to Trigger (TTT) timer, LTE threshold (LTEth), D2D threshold (D2Dth) and Time to Trigger of D2D (TTTD). HOM is a constant variable representing a threshold of the difference between the strength of the received signal to the source eNB and the strength of the received signal to the target eNBs.…”

“…It is ensured by the value of HOM that the target eNB is the most appropriate for Proximity Services (Prose). Value of TTT is the time interval required to satisfy HOM condition, as stated in [28].Once TTT condition is satisfied, then the handover action can be successfully completed. Different values of TTT can be used by ProSe UEs.…”

Abstract-A constant need to increase the network capacity for meeting the growing demands of the subscribers has led to the evolution of cellular communication networks from the first generation (1G) to the fifth generation (5G). There will be billions of connected devices in the near future. Such a large number of connections are expected to be heterogeneous in nature, demanding higher data rates, lesser delays, enhanced system capacity and superior throughput. The available spectrum resources are limited and need to be flexibly used by the mobile network operators (MNOs) to cope with the rising demands. An emerging facilitator of the upcoming high data rate demanding next generation networks (NGNs) is device-to-device (D2D) communication. An extensive survey on device-to-device (D2D) communication has been presented in this paper, including the plus points it offers; the key open issues associated with it like peer discovery, resource allocation etc, demanding special attention of the research community; some of its integrant technologies like millimeter wave D2D (mmWave), ultra dense networks (UDNs), cognitive D2D, handover procedure in D2D and its numerous use cases. Architecture is suggested aiming to fulfill all the subscriber demands in an optimal manner. The Appendix mentions some ongoing standardization activities and research projects of D2D communication.Index Terms-Mobile network operators (MNOs), peer discovery, ultra dense networks (UDNs), millimeter wave (mmWave), next generation networks (NGNs), device-to-device (D2D) communication I. INTRODUCTIONoday the number of hand-held devices is drastically increasing, with a rising demand for higher data rate applications. In order to meet the needs of the next generation applications, the present data rates need a refinement. The fifth generation (5G) networks are expected and will have to fulfill these rising demands. A competent technology of the next generation networks (NGNs) is Deviceto-Device (D2D) Communication, which is expected to play an indispensable role in the approaching era of wireless communication. The use of D2D communication did not gain much importance in the previous generations of wireless communication, but in 5G networks, it is expected to be a vital part. The rising trends between the devices, enhance spectral efficiency and system capacity [2], with reduced latency within the networks. Such a technique is essential for fulfilling the chief goals of the mobile network operators (MNOs).D2D communication allows communication between two devices, without the participation of the Base Station (BS), or the evolved NodeB (eNB). Proximate devices can directly communicate with each other by establishing direct links. Due to the small distance between the D2D users, it supports power saving within the network, which is not possible in case of conventional cellular communication.It promises improvement in energy efficiency, throughput and delay. It has the potential to effectively offload traffic from the network core. Hence, it is a very ...

Device-to-device (D2D) communication proposes a new epitome in mobile networking to avail data exchange between physically proximate devices. The exploitation of D2D communication enables mobile operators to harvest short range communications for improving network performance and corroborating proximity-based services. In this article, we investigate mobility aspects of D2D communication, which are indispensable for the adoption and implementation of D2D communication technology. We present an extensive review of the state-of-theart problems and the corresponding solutions for encouraging the exploitation of mobility to assist D2D communication. Specifically, by identifying the mobility models, traces, problems, requirements, and features of different proposals, we discuss the lessons learned and summarize the advantages of mobility-aware D2D communication. We also present open problems and highlight future research directions concerning D2D communication applications in real-life scenarios. To the best of our knowledge, this is the first comprehensive survey to address mobility-aware D2D communication, which offers insight to the underlying problems and provides the potential solutions. Index Terms-Device-to-device communication, mobility, mobile communication, mobile data traffic. I. INTRODUCTION D EVICE-to-device (D2D) communication takes the advantage of opportunistic encounters by mobile users with each other [1]. These opportunistic encounters' information between users are highly related to their movement. By exploiting users' movement, D2D enabled applications and services visualize highly opportunistic and unpredictable human mobility. Therefore, the challenges of exploiting mobility resides in the inherent complexity of users' mobility. It is mainly concerns with predicting the establishment of communication links among D2D users. For instance, two mobile users can establish a link at the time when they are in close proximity to each other. However, there are two key questions have to M.

The rapid growth and innovation of the various mobile communication technologies have caused a change in the paradigm of Internet access. In next-generation mobile system, which is also known as fifth-generation (5G) network, all user connections are expected to be heterogeneous in nature. Hence, an intelligent mobility management mechanism is essential to satisfy the requirements of lower latency, less power consumptions, and last but not least, possible uninterrupted ongoing session when a user equipment (UE) moves across network boundaries.On the other hand, device-to-device (D2D) communication has been proposed as a promising technology to boost the network performance in 5G. The issue related to mobility management for D2D communication in 5G heterogeneous network environments has attracted attention from academic society. In this paper, we leverage on IEEE 802.21 Media Independent Service (MIS) and propose a new framework, enhanced version of IEEE 802.21 MIS that supports D2D communication (E-MIS-D2D) to enhance D2D mobility experience over heterogeneous networks. Moreover, a load-aware mode selection algorithm is proposed for selecting the best target mode. Through extensive simulation studies, we validate that the proposed method outperforms the existing methods in terms of packet loss ratio, average throughput, latency, bandwidth usage, and load rate of Evolved Node B (eNB). KEYWORDSdevice-to-device, heterogeneous networks, load-aware, media independent service, mobility management INTRODUCTIONThe improved multimedia availability and the rapid development of smart devices have resulted in the explosive growth of mobile traffic that constantly challenge inherently limited network resources in currently available IMT-Advanced/4G networks. According to an Ericson Mobility Report 2017, mobile subscriptions will rise to 9.12 billion by year 2023. 1 To handle such explosive growth of traffic volume, the quest for the 5G mobile communication standards has been going on actively recently, and one of the major focuses of this quest is to obtain a device-centric network architecture. 2 D2D communication with its nature of proximity-based service and enhancements on network capacity and spectrum efficiency has been viewed as a key component in 5G. By using D2D communication, one device enables to communicate with another device directly without the supports from a major infrastructure. However, the implementation of D2D communications faces a number of challenges. One big issue is the mobility management problem caused by D2D communications when a user in D2D pair moves across network boundaries, especially in heterogeneous network scenarios. Mobility management for any wireless communication systems has been regarded as the high-priority issue. However, the research on mobility management for D2D communication is in an early stage so far, and it is still an open question.In this paper, we focus on the IEEE 802.21 specified MIS 3 and point out ways to enhance the mobility experience of D2D communication users in he...
