Coexistence of Wi-Fi and LTE-LAA Networks: Open issues

2018 · ARTICLE · en

An increase in the network capacity is a requirement for modern LTE cellular networks. A part of the RF spectrum that is available for transmission is among the most important limiting factors. Such a problem can be solved in the LTE networks using unlicensed bands that are employed in alternative (e.g., Wi-Fi) technologies with the aid of a new LTE-LAA technology. In this work, we perform a comparative analysis of the channel access procedures for unlicensed bands that are described in the Wi-Fi standard and LTE-LAA specification and discuss open problems of coexisting technologies.

ARBAT: A flexible network architecture for QoE-aware communications in 5G systems

2018 · ARTICLE · en

The expansion of the service scope of cellular networks to include a wide variety of services such as mobile broadband, Internet of Things, and mission-critical machine-type communications has significantly shaped the evolution towards 5G and beyond systems. All these services impose divergent and often mutually exclusive requirements in terms of data rate, latency, and energy efficiency. To satisfy heterogeneous requirements, 5G systems should have properties such as Quality-of-Experience awareness, adaptability and flexibility, scalability and reliability, support for multiple RATs, and backward compatibility, all at a low CAPEX and OPEX. To this end, software-defined networking and network function virtualization have been envisioned as key enabling technologies for 5G, and represent a major paradigm shift for 5G systems. In recent years, a plethora of software-defined mobile network architectures have been introduced worldwide, each with their unique features and drawbacks. Within this context, this paper introduces a new architecture called ARBAT which has been designed to satisfy and exceed the requirements put forth by 5G. ARBAT is characterized by many innovative features such as the Universal Network Device and Unified Cellular Network concepts, multi-slice modular resource management with the AirHYPE wireless hypervisor, network-user application interaction through the xStream platform, and simplified multi-tenant orchestration through ServiceBRIDGE. The novel features of the ARBAT infrastructure plane, data plane, control plane and Management and Orchestration entity are also explained in the paper in detail. Furthermore, a qualitative evaluation and feature comparison of ARBAT with other state-of-the-art architectures is conducted to demonstrate that ARBAT satisfies the aforementioned objectives of the 5G systems.

Scheduling for Downlink Non-Orthogonal Multiple Access in Wi-Fi Networks

2018 · CHAPTER · en

Non-orthogonal multiple access (NOMA) is a radio access technology that allows significantly improving network performance in scenarios with high heterogeneity. While being typically studied for cellular networks, NOMA can also be used in Wi-Fi networks. This paper proposes a scheduling approach for NOMA-aware resource scheduling in Wi-Fi. This approach is implemented to design NOMA-aware downlink schedulers which follow such wide-spread strategies as max-rate, proportional-fair and shortest-remaining-processing-time.

Two-Slot Based Model of the IEEE 802.11ah Restricted Access Window with Enabled Transmissions Crossing Slot Boundaries

2018 · CHAPTER · en

Recently appeared the IEEE 802.11ah standard has introduced a new channel access mechanism, so-called Restricted Access Window (RAW). This mechanism allows an access point (AP) to reduce contention for the channel in overloaded Wi-Fi networks by limiting the number of stations simultaneously accessing the channel. The 802.11ah AP divides all associated stations into groups and allocates for each group an interval of time, which is called a RAW slot. This paper considers the RAW mechanism with enabled transmissions crossing slot boundaries, which means that a station is allowed to end the current transmission attempt even after a completion of the allocated RAW slot. We present a new mathematical model, which allows estimating throughput and energy consumption with this mechanism, and optimizing performance of RAW.

Will MCCA revive wireless multihop networks?

2017 · ARTICLE · en

Wireless multihop networks (WMNs) are very favorable for many emerging applications, including those connected with public safety, Internet of Things or future Next Generation 60 GHz communication. However, the hidden station problem dramatically degrades efficiency of WMNs and impedes extensive usage of these networks. To eliminate the effect of hidden stations in Wi-Fi mesh networks, the latest version of the IEEE 802.11 standard proposes using deterministic channel access called MCCA. In the paper, we analyze this mechanism, focusing on both already achieved results and open issues.

Radio Resource Scheduling for Low-Latency Communications in LTE and beyond

2017 · CHAPTER · en

In this paper, we consider the problem of radio resource scheduling for Industrial Internet and Tactile Internet. Both paradigms - being revolutionary drivers of 5G - are tightly connected with low-latency communications (i.e. latency of the order of 10 ms or even less). We give an original mathematical statement of the radio resource scheduling problem and propose a novel algorithm which solves this problem using the dynamic programming method. With simulations we show that the proposed algorithm outperforms ones found in literature both in terms of goodput (i.e. the amount of data delivered to users within delay budget) and number of users with satisfied QoS requirements. Finally, we discuss how the developed algorithm can be implemented in real networking equipment.

SEBRA: SAND-Enabled Bitrate and Resource Allocation algorithm for network-assisted video streaming

2017 · CHAPTER · en

Dynamic Adaptive Streaming over HTTP (DASH) is a predominant technology for delivering video in wired and wireless networks. With DASH, clients can adaptively select the quality (bitrate) of the downloaded video. To improve Quality of Experience (QoE), a recently standardized framework, called Server and Network Assisted DASH (SAND), allows the client and the server to exchange control information with intermediate network nodes, e.g., with Wi-Fi Access Point (AP). In the paper, we show that such a framework is especially fruitful for short videos, which becomes more and more important nowadays. Specifically, we design a novel centralized algorithm, called SEBRA, which runs at the AP. It both allocates video bitrates and distributes channel time among all video clients. With simulations, we show that the designed algorithm significantly improves QoE compared to the existing solutions.

Reliable Low Latency Communications in LTE Networks

2017 · CHAPTER · en

hot topic recently attracted much interest in 3GPP community is ultra reliable low latency communications. While specific protocols for such type of communications are under development, in this paper we evaluate how well we can meet strict quality of service requirements in the current LTE/LTE-Advanced networks. Specifically, we design a new two-step radio resource management algorithm for reliable low latency communications. At the first step, the algorithm forms a high-priority group of users which can be reliably served within the given delay budget. At the second step, the algorithm solves a linear optimization problem and allocates resource blocks to meet quality of service requirements at least for the users from the high-priority group. With simulations, we show that the proposed algorithm outperforms existing ones in terms of goodput, PLR and the number of satisfied users.

SAND-inspired Cross-layer Approach for CCTV in 5G Networks

2017 · CHAPTER · en

In this work, we propose an approach to deploy and manage resources in a surveillance system, based on cellular technologies. In such a system, on one hand, the data from CCTV cameras should be reliably delivered with as higher quality as possible within several seconds after they were generated to enable near real-time surveillance. On the other hand, the Web traffic, which is generated in public cellular networks shall be delivered with the same quality as if there were no CCTV at all. In the paper, we propose an approach of how to design such a system based on the 5G technology and how to organize transmission to satisfy the described requirements and provide near-optimal quality of the generated video.

Analysis of Algorithms for Decentralized Dynamic Channel Resource Reservation for Data Streaming in Wi-Fi Networks

2017 · ARTICLE · en

В данной работе исследуется класс алгоритмов динамического децентрализованного резервирования ресурсов в сетях Wi-Fi, при использовании которых каждая станция заранее выбирает и резервирует интервалы времени для будущей передачи. Чтобы избежать интерференции, информация о зарезервированных интервалах регулярно рассылается соседним станциям. При этом для минимизации объема рассылаемой служебной информации зарезервированные интервалы строго периодичны и имеют одинаковую дли- тельность. Разработаны два алгоритма децентрализованного резервирования ресурсов, и с помощью математического моделирования доказано их превосходство в смысле минимизации объема фактически занятых канальных ресурсов при передаче потоковых данных пульсирующей интенсивности с заданными требованиями к качеству обслуживания по сравнению с известным алгоритмом. Разработанные алгоритмы могут быть использованы для распределения ресурсов между базовыми станциями в плотных инфраструктурных сетях и для распределения ресурсов между меш-станциями в самоорганизующихся сетях Wi-Fi.
