“…Transmission latency [57][58][59] refers to the time interval (delay) that occurs when propagating the input data from the source to the destination over a communication link. In rendering enhanced quality of service (QoS) delivery and user quality of experience (QoE), the emerging 5G networks are specified to offer about 10-100 times higher user data rates and lower energy consumptions in comparison to the present LTE based networks [60,61]. These networks will also offer ultra-low and reliable end-to-end latency of less than 1 ms [61] with very high reliability (that is, very low packet error rate).…”

The advancement in wireless communication applications encourages the use of effective and efficient channel estimation (CE) techniques because of the varying behaviour of the Rayleigh fading channel. In most cases, the emphasis of most proposed CE schemes is to improve the CE performance and complexity for ensuring quality signal reception and improved system throughput. Candidate waveforms whose designs are based on filter bank multi-carrier (FBMC) modulation techniques such as filter bank orthogonal frequency division multiplexing based on offset quadrature amplitude modulation (OFDM-OQAM), universal filtered multicarrier (UFMC) and generalised frequency division multiplexing based on offset quadrature amplitude modulation (GFDM-OQAM) are no exception to the use of these proposed CE techniques in the literature. These schemes are considered as potential waveform candidates for the physical/media access control layer of the emerging fifth generation (5G) networks. Therefore, pinpoint CE techniques represent an important requirement for these waveforms to attain their full potentials. In this regard, this paper reviews the concept of CE as applicable to these waveforms as well as other waveform candidates under consideration in the emerging 5G networks. Since the design of the majority of the waveform candidates is filter based, a review of the general filter design considerations is presented in this paper. Secondly, we review general CE techniques for candidate waveforms of next generation networks and classify some of the studied CE techniques. In particular, we classify the CE schemes used in filter bank OFDM-OQAM and GFDM-OQAM based transceivers and present a performance comparison of some of these CE schemes. Besides, the paper reviews the performances of two linear CE schemes and three adaptive based CE schemes for two FBMC based waveform candidates assuming near perfect reconstruction (NPR) and non-perfect reconstruction (Non-PR) filter designs over slow and fast frequency selective Rayleigh fading channels. The results obtained are documented through computer simulations, where the performances of the studied CE schemes in terms of the normalised mean square error (NMSE) are analysed. Lastly, we summarise the findings of this work and suggest possible research directions in order to improve the potentials of the studied candidate waveforms over Rayleigh fading channels.

“…The main authentication entities of the SAK-AKA scheme are the home subscriber server (HSS), mobility management entity (MME), and user equipment (UE) [3]. When the UE requests a particular network service such as a location update, call origination, call termination, or multimedia streaming, an authentication process with the network (i.e., MME and HSS) should be performed to validate the service request type and to ensure that the UE is authorized to use such services [9], [12], [13], [14], [15]. Additionally, the authentication process with the UE in the opposite direction should also be performed.…”

One of the recently proposed authentication schemes for 4G/5G mobile networks is a secure anonymity key of authentication and key agreement scheme (SAK-AKA), wherein the home subscriber server (HSS), mobility management entity (MME), and user equipment (UE) represent authentication entities. In the SAK-AKA scheme, UE authentication is performed through an initial authentication processes session (IAPS) and subsequent authentication processes session (SAPS) phases to ensure that the UE is authorized to use the network services. In IAPS, the MME accesses the HSS to obtain the authentication parameters and delegates the HSS to execute the authentication process with the UE mutually. Since accessing the HSS is expensive, the HSS generates a number (k) of authentication vectors (AVs) and then sends them back to the MME one at a time. SAPS is then executed (k) times to authenticate the UE without going back to the HSS. Therefore, it is useful to choose a specific value of (k) that would reduce the traffic cost. In this paper, we proposed an analytical cost function model to examine the effect of the (k) value on the transmission cost of authentication processes. The proposed model assumes that the signaling traffic of the SAK-AKA scheme is represented by a Poisson process where the authentication request time has an exponential distribution. This model was analyzed numerically to identify appropriate values of the (k-AVs) that can minimize the overhead messages cost of the SAK-AKA scheme.

“…It can benefit this era where social networks are sharing huge data and video transfer across the world. NGMN consists of two layers [1] including transport layer and service control layer where the former manages the connectivity and transmission using WiMAX, UMTS, and LTE and the latter utilizes IMS servers for registration, integration, charging, and policy enforcement as per 3rd Generation Partnership Project (3GPP). User equipment (UE) connects through transport layer and then registers with IP Multimedia Subsystem (IMS) using service control layer in most access networks such as LTE/LTE-A.…”

Next generation mobile networks aim to provide faster speed and more capacity along with energy efficiency to support video streaming and massive data sharing in social and communication networks. In these networks, user equipment has to register with IP Multimedia Subsystem (IMS) which promises quality of service to the mobile users that frequently move across different access networks. After each handover caused due to mobility, IMS provides IPSec Security Association establishment and authentication phases. The main issue is that unnecessary reregistration after every handover results in latency and communication overhead. To tackle these issues, this paper presents a lightweight Fast IMS Mobility (FIM) registration scheme that avoids unnecessary conventional registration phases such as security associations, authentication, and authorization. FIM maintains a flag to avoid deregistration and sends a subsequent message to provide necessary parameters to IMS servers after mobility. It also handles the change of IP address for user equipment and transferring the security associations from old to new servers. We have validated the performance of FIM by developing a testbed consisting of IMS servers and user equipment. The experimental results demonstrate the performance supremacy of FIM. It reduces media disruption time, number of messages, and packet loss up to 67%, 100%, and 61%, respectively, as compared to preliminaries.
