The 5th generation (5G) wireless networks propose to address a variety of usage scenarios, such as enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency (URLLC). Due the exponential increase in user equipment (UE) devices communication technologies, 5G beyond (B5G) expect support far higher density lower latency than currently deployed cell...

5G is the fifth generation wireless network, with a set of characteristics, such as high bandwidth and data rates, massive connectivity, broad coverage, low latency. The scenarios using include enhanced Mobile Broadband (eMBB), Machine Type Communications (mMTC), ultra-Reliable Low-Latency (uRLLC). expected to support wide variety applications, city management, healthcare, transportation, agric...

5G wireless networks will be extremely dense, given the projected increase in number of users and access points (APs), as well heterogeneous, different types APs applications being accessed by users. In such challenging environments, efficient mobility management (MM), specifically user association, critical to assist provisioning Quality Service (QoS) diverse targets serve. Whilst determining ...

As such, the 5G ecosystem opens up an opportunity to integrate terrestrial and satellite systems in order achieve goal of attributes mentioned above (i.e., global seamless connectivity, ubiquity, coverage, security, resiliency) across family use cases—eMBB, URLLC, mMTC. It is not only throughput ubiquity that are crucial; latency reliability now becoming important metrics future provide accepta...

Application Layer Multicast (ALM) is a promising technology for constructing content delivery systems across the Internet with low cost and scalability. Unlike the conventional, well-known IP Multicast paradigm, ALM uses unicast to virtually realize multicast communications. In this article, we present a survey of state-of-the-art techniques for designing efficient ALM trees and the challenges ...
