The Cognitive Radio (CR) or intelligent radio becomes increasingly an anticipated and promising solution to manage spectrum efficiency problems. The most challenging scenario is represented by CR ad hoc networks (CRAHNs) because of their dynamic and flexible nature. The performance of such networks can be further improved by using directional transmissions. This work proposes to use lightweight directional antennas with a fixed beam on small Unmanned Aerial Vehicles (UAVs) and evaluates their performance using software simulations. We show that a rotation of an UAV can be used to point a beam in a desired direction. In this case, a system capacity becomes higher comparing to an omnidirectional transmission. The negative impact of the mechanical rotation is discussed as well.

An efficient and fair network resource allocation is crucial for both operators as well as users. This paper analyses the performance and fairness properties of transport-layer based resource assignment methods for individual flows on a bottleneck link. To find an optimum trade-off between maximization of the overall bandwidth and fairness, the assignment problem is solved using (non-)linear programming expressed by the objective function and various constraints. For bottleneck fairness, a factor alpha is introduced where non-zero values penalize flows which occupy multiple bottlenecks, resulting in an increase of the overall throughput while sometimes reducing the fairness, which reflects the behaviour of TCP in multi-bottleneck scenarios. For two example scenarios, the results of the introduced objective functions and fairness methods are discussed and their properties compared quantitatively by means of well-known performance metrics. It is shown that, even though the investigated methods yield different bandwidth allocations for the individual flows, the performance metric results are similar for both fairness as well as throughput, so for complex scenarios which require a large amount of calculations, a method with a low computational effort, i. e. including only linear components can be selected.

This paper describes scenarios and services based on Federated Identity technology. The authors emphasize the Single Sign On mechanism, in which a user's single authentication credential is used to log in once without being prompted to authenticate again to other systems. The overview of Federated Identity and a Federated Identity Management System is presented first. Next, federation approaches used in different fields of human activity are discussed. A few examples of such domains are presented: E-health, E-government, E-learning, and E-business. Also, two different use cases were proposed: a federated approach for tourism which provide a better service for customers, and in the health care sector, which improves medical service quality and reduces treatment costs. The last section describes the prototype which was implemented and tested in network environment.

Cloud Radio Access Network (C-RAN) architecture has been proposed as a promising solution to overcome the challenges of Next Generation (5G) cellular networks, in terms of efficiency, capacity, scalability, flexibility and sustainability in a cost-effective and power efficient way. However C-RAN demands a new energy consumption model and its resources optimised. This Paper presented the C-RAN to reduce the network cost further by dynamically allocating centralised Base Band Unit (BBU) resources to Remote Radio Heads (RRHs) depending on the traffic conditions. New energy consumption model for C-RAN has been proposed for capturing the energy consumption of centralised BBU resources which reflect the dynamic allocation of RRHs. An algorithm that optimises the BBU resource allocation has been proposed. BBUs are put to sleep and active states by switching them `OFF' and `ON' respectively according to their resource usage. Numerical results based on simulation settings validated the theoretical analyses and revealed more than 70% power reduction compared to conventional RAN under the EARTH power model.

In this paper, we establish a unifying framework to analyze symbol error probability (SEP) for wireless communication where the fading envelope is described by H-fading or degree-2 irregular H-fading. By virtue of two essential operations-termed as Mellin and convolution operations- involved in the Mellin transform and Mellin convolution of two H-functions, the H-transform for the SEP culminate in H-functions. Using the algebraic asymptotic expansions of the H-transform, we further analyze the SEP at high signal-to-noise ratios in again a unified fashion.

In this paper, we present and evaluate a low-cost platform, able to emulate multiple primary and secondary users with a single Software Defined Radio (SDR) device. By effectively exploiting techniques that are applicable to OFDM, we manage to transmit simultaneously multiple DVB-T channels, along with IEEE 802.11a/g and wireless microphone signals. Utilizing a single PC with open-source software and a SDR device we are able to substitute multiple appliances, such as expensive and specialized laboratory equipment. The proposed platform can also serve as an efficient real-time multiple users testbed for complex cognitive radio (CR) scenarios and techniques validation, 5G modulations testing-prototyping, and heterogeneous wireless networking exploration.

The Control Orchestration Protocol (COP) abstracts a common set of control plane functions used by an various SDN controllers, allowing the interworking of heterogeneous control plane paradigms (i.e., OpenFlow, GMPLS/PCE). COP has been defined using YANG model language and can be transported using RESTconf, which is being incorporated by industry. COP has been defined in the scope of STRAUSS due to the need for an overarching control plane protocol for network orchestration. In this paper, several research projects describe how the COP could fit in their architecture and propose a use case for COP usage. The proposed COP use cases cover the following research projects: STRAUSS, IDEALIST, DISCUS, COMBO, INSPACE.

Nowadays telecommunication operators which manage various network types are looking for convergence in different domains, from the access and aggregation to the core network. Moreover, in future 5G networks, the explosion of Internet of Things and the need of fixed and mobile convergence will imply strong requirements for more simplified and unified subscriber management. This will lead notably to seamless user experience when moving from a network to another. This paper proposes a pragmatic approach to operators for moving their networks smoothly to a really convergent subscriber data and session management system. It takes into account legacy mechanisms of subscriber management and introduces a universal Authentication, Authorization and Accounting (AAA) which aims at replacing progressively the legacy subscriber databases and helps in moving to a unified logical network element that will manage all subscriber's data and sessions. This paper illustrates the proposals with some use cases.

Deploying smallcell networks achieves great spatial reuse at the cost of severe cross-tier interference from concurrent transmission. This paper addresses the downlink cross-tier interference pricing and power control for orthogonal frequency division multiple access (OFDMA) heterogeneous Networks (HetNets), where a macrocell underlaid with several femtocells.We assume that the macrocell protects its transmission by pricing the interference on each orthogonal subchannel and each femtocell base station (FBS) determines the power allocation strategy accordingly.Then, a Stackelberg game is used to formulate the mentioned model. Existence and uniqueness of the Stackelberg equilibrium (SE) are analyzed. In addition, a distributed interference pricing and power update algorithm (DIPPU) with guaranteed convergency is proposed to achieve the SE. Simulation results validate the proposed algorithm and show its fast convergence. Due to the non-cooperative manner, the proposed scheme can approach the cooperative scheme in terms of capacity of femtocells with reduced communication overhead effectively.

Wi-Fi Direct is one of the most prevailing technologies in the field of wireless networking. With the advent of various useful applications, it is facing many challenges namely: efficient group formation/communication, power saving, compatibility issues etc. In this paper, we focus on the fundamental problem of reliability in multicast communication in the context of Wi-Fi Direct. To this end, our paper makes the following contributions: 1) It explores the problems of multicast in the context of Wi-Fi Direct. 2) It checks the performance of Standard Multicast (SM) and Leader Based Multicast (LBM) protocols for Wi-Fi Direct. 3) It presents an Enhanced Leader Based Multicast (ELBM) protocol for Wi-Fi Direct. The ELBM reduces collision and interference of multicast data transmission by improving channel access mechanism and selecting an optimal representative multicast receiver, therefore, it enhances the reliability of multicast transmission. We have tested the performance of all the three protocols through simulations. The simulation results show that the ELBM increases throughput of multicast transmission by up to two times compared to the existing mechanisms, as well as improving packet delivery ratio of multicast data.
