The coordination of base stations in mobile access networks is an important approach to reduce harmful interference and to deliver high data rates to the users. Such coordination mechanisms, like Coordinated Multi-Point (CoMP) where multiple BSs transmit data to a user equipment, can be easily implemented when centralizing the data processing of the base stations, known as Cloud RAN. This centr...

As wireless communication evolves towards 5G, both fixed broadband and mobile broadband will play a crucial part in providing the Gbps infrastructure for a connected society. This paper proposes a Millimeter-wave Gbps Broadband (MGB) system as the solution to two critical problems in this evolution: last-mile access for fixed broadband and small cell backhaul for mobile broadband. The key idea ...

Many data sets, such as system logs, are generated from widely distributed locations. Current distributed systems often discard this data because they lack the ability to backhaul it efficiently, or to do anything meaningful with it at the distributed sites. This leads to lost functionality, efficiency, and business opportunities. The problem with traditional backhaul approaches is that they ar...

Content caching at the base station of the Radio Access Network (RAN) is a way to reduce backhaul transmission and improve the quality of experience. So it is crucial to manage such massive microcaches to store the contents in a coordinated manner, in order to increase the overall mobile network capacity to support more number of requests. We achieve this goal in this paper with a novel caching...

in densely populated areas. A typical mobile-backhaul network has thousands of hops, and operators must be able to increase microwave capacity without having to change frequency planning and replace equipment across their entire network. This article reviews current and future microwave solutions with the potential for Gbps backhaul capacity levels, for rural and urban areas. The solutions pres...

Wireless networks are becoming extremely pervasive while traffic demand is ever increasing. In order to cope with the forecast increase in traffic volume for the upcoming years, as well as the number of connected devices, new technologies, practices and spectrum rearrangements are required. In this context, a key question arises: how to provide extensive backhaul connectivity and capacity for p...

Multi unmanned aerial vehicle (UAV) network is a promising solution to providing wireless coverage ground users in challenging rural areas (such as Internet of Things (IoT) devices farmlands), where the traditional cellular networks are sparse or unavailable. A key challenge such 3-D placement all UAV base stations (BSs) that formed multi-UAV network: 1) utilizes minimum number UAVs while ensur...

In 5G ultradense heterogeneous networks, wireless backhaul, as one of the important base station (BS) resources that affect user services, has attracted more and attention. However, a would access to BS which is nearest for based on conventional association scheme, constrains network performance improvement due limited backhaul capacity. this paper, using backhaul-aware semiclosed expressions m...

Cooperative technology is expected to have a great impact on the performance of cellular or, more generally, infrastructure networks. Both multicell processing (cooperation among base stations) and relaying (cooperation at the user level) are currently being investigated. In this presentation, recent results regarding the performance of multicell processing and user cooperation under the assump...
