In this work, we investigate on minimizing the energy consumption of a wireless backhaul communication network through a joint optimization problem of data routing and radio configuration. The backhaul network is modeled by a digraph in which the nodes represent radio base stations and the arcs denote radio links. According to the scenario under consideration, a power efficient configuration ca...

Degrees of freedom (DoF) gains are studied in wireless networks with cooperative transmission under a backhaul load constraint that limits the average number of messages that can be delivered from a centralized controller to the basestation transmitters. The backhaul load is defined as the sum of all the messages available at all the transmitters per channel use, normalized by the number of use...

The success of LTE heterogeneous networks heavily depends on the efficient interplay between user association and uplink/downlink resource allocation. Much work has been devoted to investigate this interaction and to capture the involved trade-offs. Nevertheless, different schemes are based on different assumptions and optimization objectives (e.g., improve throughput, delay, load balancing, et...

Rural areas have very low revenue potential. The major issue in providing low-cost broadband to rural areas is to provide reliable backhaul connections that spread over tens or even hundreds of miles, connecting villages to the nearest service provider. Along with aerial networks of Google and Facebook, there has been a considerable amount of research toward long-distance terrestrial WiFi links...

In cellular communication systems with frequency reuse factor of one, user terminals (UT) at the cell-edge are prone to intercell interference. Joint processing is one of the coordinated multipoint transmission techniques proposed to mitigate this interference. In the case of centralized joint processing, the channel state information fed back by the users need to be available at the central co...

In this paper, we study the problem of joint in-band backhauling and interference mitigation in 5G heterogeneous networks (HetNets) in which a massive multiple-input multipleoutput (MIMO) macro cell base station equipped with a large number of antennas, overlaid with self-backhauled small cells is assumed. This problem is cast as a network utility maximization subject to wireless backhaul const...

Recent work has shown that multi-cell cooperative signal processing in cellular networks can significantly increase system capacity and fairness. For example, multi-cell joint transmission and joint detection can be performed to combat inter-cell interference, often mentioned in the context of distributed antenna systems. Most publications in this field assume that an infinite amount of informa...

Communications from remote areas that may be of interest is still a problem. Many innovative projects applied to remote sites face communications difficulties. The GOLDFISH project was an EU-funded project for river pollution monitoring in developing countries. It had several sensor clusters, with floating WiFi antennas, deployed along a downstream river's course. Sensor clusters sent messages ...

Multicell processing in the form of joint encoding for the downlink of a cellular system is studied under the realistic assumption that the base stations (BSs) are connected to a central unit via finitecapacity links (finite-capacity backhaul). Three scenarios are considered that present different tradeoffs between global processing at the central unit and local processing at the base stations ...

We are in the presence of the VRP with backhauls, also known as the linehaul-backhaul problem, when the vehicles are not only required to deliver goods to customers, but also to pick up goods at customers locations. An example of this partition of the set of customers could be the grocery industry. The supermarkets and shops are the linehaul customers and the grocery suppliers are the backhaul ...
