The Internet is now present in our personal and professional life, where reliability and green communications are still open issues to be addressed. Usually, clients establish Service Level Agreements (SLAs) with their Internet Service Providers (ISPs), including parameters of reliability and bandwidth. On the other hand, the ISPs aim to maximize their profit by establishing…

The Uplink of Distributed MIMO: Wireless Network Coding v.s. Coordinated Multipoint
In this paper, we propose an advanced transmission protocol for the next generation wireless access network using wireless network coding (WNC). As an alternative to conventional cooperative multipoint (CoMP) as described in LTE-A, WNC enables access point cooperation, combining the flows using network coding functions, instead of sending multiple separate information flows across the backhaul…
Service Class Resource Management for Green Wireless-Optical Broadband Access Networks (WOBAN)
Exponential growth in the volume of wireless data, boosted by the growing popularity of mobile devices, such as smartphone and tablets, has forced the telecommunication industries to rethink the way networks are currently designed, and to focus on the development of high-capacity mobile broadband networks. In response to this challenge, researchers have been working toward…
A programmable and virtualized network & IT infrastructure for the internet of things: How can NFV & SDN help for facing the upcoming challenges
The Internet of Things (IoT) revolution has major impacts on the network & Information Technology (IT) infrastructure. As IT in the past decade, network virtualization is simultaneously on its way with for instance Network Functions Virtualization (NFV) and Software-Defined Networking (SDN). NFV and SDN are approaches enhancing the infrastructure agility thus facilitating the design, delivery…
GFlow: Towards GPU-based high-performance table matching in OpenFlow switches
This paper investigates the acceleration of Software-based OpenFlow switches, equipped with commodity off-the-shelf hardware, for high-performance table matching. Particularly, due to the high flexibility and compatibility, software-based and SDN-compatible switches, such as OpenvSwitch, has been widely applied in several viable fields, like cloud services, future Internet architectures, and the network function virtualization (NFV). In these…
A New Pan-Sharpening Method With Deep Neural Networks
A deep neural network (DNN)-based new pansharpening method for the remote sensing image fusion problem is proposed in this letter. Research on representation learning suggests that the DNN can effectively model complex relationships between variables via the composition of several levels of nonlinearity. Inspired by this observation, a modified sparse denoising autoencoder (MSDA) algorithm is…
Asymptotic Deployment Gain: A Simple Approach to Characterize the SINR Distribution in General Cellular Networks
In cellular network models, the base stations are usually assumed to form a lattice or a Poisson point process (PPP). In reality, however, they are deployed neither fully regularly nor completely randomly. Accordingly, in this paper, we consider the very general class of motion-invariant models and analyze the behavior of the outage probability (the probability…
Semi-Persistent RRC Protocol for Machine-Type Communication Devices in LTE Networks
In this paper, we investigate the design of a radio resource control (RRC) protocol in the framework of long-term evolution (LTE) of the 3rd Generation Partnership Project regarding provision of low cost/complexity and low energy consumption machine-type communication (MTC), which is an enabling technology for the emerging paradigm of the Internet of Things. Due to the nature…
On the Nanoscale Electromechanical Wireless Communication in the VHF Band
Electromagnetic communication at the nanoscale has, to date, been studied in either the very high frequency (VHF) (30-300 MHz) or in the TeraHertz band (0.1-10 THz). The main focus of this paper is on electromagnetic communication in the VHF band and determining the bit error rate (BER) performance of nanoscale receivers utilizing a carbon nanotube (CNT). To determine BER…
Spectrum occupancy measurement: An autocorrelation based scanning technique using USRP
This paper presents a technique for scanning and evaluating the radio spectrum use. This technique determines the average occupancy of a channel over a specific duration. The technique was implemented using Software Defined Radio units and GNU Radio software. The survey was conducted in Grand Forks, North Dakota, over a frequency range of 824 MHz to 5.8 GHz. The results of…
