The current virtualization solution in the Cloud widely relies on hypervisor-based technologies. Along with the recent popularity of Docker, the container-based virtualization starts receiving more attention for being a promising alternative. Since both of the virtualization solutions are not resource-free, their performance overheads would lead to negative impacts on the quality of Cloud services...
Most Information Technology (IT) services nowadays rely on one or multiple data centers. In this paper, we propose a Quality of Service (QoS) scheme for Intra/Inter data center communications systems. The proposed scheme is based on differentiation of traffic into different class categories. The differentiation is based on the source of traffic as well as the specific traffic's requirements. We conduct...
Wi-Fi Mesh Community has turn out to be an important area community to offer internet to challenge the thrown domains and wireless link in metropolitan environments. In this paper, hassle of figuring out the most to be had bandwidth direction is targeted, which is an essential problem in helping pleasant-of-carrier in WMCs. Due to the concept of interference, bandwidth, which is a familiar challenging...
In 2013, U. S. data centers accounted for 2.2% of the country's total electricity consumption, a figure that is projected to increase rapidly over the next decade. Many important workloads are interactive, and they demand strict levels of quality-of-service (QoS) to meet user expectations, making it challenging to reduce power consumption due to increasing performance demands. This paper introduces...
GPUs have been widely adopted in data centers to provide acceleration services to many applications. Sharing a GPU is increasingly important for better processing throughput and energy efficiency. However, quality of service (QoS) among concurrent applications is minimally supported. Previous efforts are too coarse-grained and not scalable with increasing QoS requirements. We propose QoS mechanisms...
In this paper, we address the problem of energy-aware user satisfaction in self-organizing networks. Our main objective is to meet with the users requirements while reducing energy consumption. Accordingly, we aim at seeking satisfaction equilibria, mainly the efficient satisfaction equilibrium (ESE). We first define conditions of existence and uniqueness of ESE. Considering information-theoretic...
To mitigate performance anomalies due to different transmission rates and improve throughput performance in ad-hoc networks, we propose a method called user cooperative mobility in which a node, i.e., a user of an ad-hoc network, moves (changes its geometrical position) for communication. Unlike previous research regarding user cooperative mobility, it is not easy to decide to where the user should...
Today, Cloud Computing provides many technological oriented applications distributed over the internet. Cloud Computing facilitate tremendous changes in the IT world, to increases the maximum profits from this new platform. In IT industry everyday new applications coming up and increases the complexity of scheduling process. For this purpose, job scheduling plays a most important responsibility in...
Wireless network is based on packet switching concept and is capable of handling various types of applications. The challenge is to attain a better Quality of Service (QoS) for the like applications of real time and non-real time in an intriguing environment with varying bit rate, unexpected channel lay off. The intention of QoS provision is to afford the opted services for the users while utilizing...
Network Functions Virtualization (NFV) is a technology for running software-based functions on commodity hardware, which can lead to cost savings and flexible functionality. However, due to the software processing of network functions, the performance of Virtualized Network Functions (VNFs) is considerably degraded in relation to the types of VNFs and the configuration of VNF applications. Therefore,...
This paper relates to the problem statement of distribution of heterogeneous information and communication system capacity among multiple service flows. We consider the case study of multi-commodity flow problem in terms of utility functions maximization. This approach differs from previously known by separating the optimization problem into layers based on Bellman's Principle of Optimality. It simplifies...
Systems comprised of Cognitive Radio Networks (CRN) have been gaining attention in the current literature, given their ability to reduce spectrum scarcity by reusing parts of the spectrum band, while at the same time ensuring a minimum Quality of Service (QoS) margin. In this regard, it becomes important to consider the CRN's usage of multiple access protocols. In this paper, we consider a CRN with...
In order to improve the performance of the EDCA mechanism, an efficient collision resolution protocol must be used. To this end, many collision reduction protocols have been proposed. However, there remain still many problems. In this paper, we propose a novel multi-slot allocation protocol to resolve the collisions. The proposed protocol uses short-duration busy-tone signals to avoid collisions and...
Transportable nodes in a healthy and demanding network set-up of Mobile Adhoc Network (MANET) are self-governing with self-configurable potential due to high occurrence of topology alteration and changeable rescheduling of the network mechanism during data communication. Due to simplicity of set up, the energetic networking system in MANET is very victorious in conditions where it is complicated to...
With the rapid growth of bandwidth-intensive applications, Carrier Aggregation (CA) has been introduced in Long Term Evolution-Advanced (LTE-A) Networks to provide higher data rates.

Indeed, the main contribution of this work is to allocate the Physical Resources Blocks (PRBs) of all Component Carriers (CCs) to Real Time (RT) and-non Real Time (NRT) users using various criteria. Our proposed...
Vehicular ad hoc network (VANET) is an emerging network technology with the goal of providing public safety, traffic coordination and infotainment for the comfort of passengers in moving vehicles. However, it faces the challenge of not providing the expected quality of service (QoS) when streaming videos online. This challenge emanate from the variable topology infrastructure caused by intrinsic high...
Lately the concepts of smart cities, smart highways and automated vehicles have been rigorously promoted in literature and it depends on the maturity of technology based on VANET (Vehicular Adhoc Network).

In nigh application, it is indispensable to discover or supervise the behavior of the surrounding situation at a fine resolution over large spatial-temporal scales therefore WSN (Wireless Sensor Network) is well-advised. Because of smaller size and low power requirement of sensor device use of WSN for watching the surrounding action is increased time to time. Numeral of sensor inside WSN is proportionate...
