Although many solutions have been proposed from both industry and academia, pricing the Internet services is still an ongoing research problem for researchers. In this paper, we propose an optimal pricing scheme for inter-AS traffic requests with QoS made by customers in Software Defined Networks (SDNs). This pricing scheme exploits the Nash bargaining problem which aims to maximize benefits of both...
This paper investigates the characteristics of Tahoe, Reno, New Reno, Vegas, and Sack, and calculated their throughputs in simulated environment using NS-2 simulator by varying various performances parameters such as bandwidth, simulation time and number of traffic sources in order to figure out which one of them is the best for which scenario. Simulation was performed to study the performance of...
Wireless networks have dynamic transmission properties as the wireless channel conditions randomly change over time due to several environmental factors. When transmitting real-time applications such as video, the dynamic properties of wireless networks can have detrimental effects on the quality of the video delivered to a user. Many Quality of Service (QoS) guarantee techniques to improve video...
In today's fast moving world, Li-Fi is emerging as one of the best technology of the Era. Its promising features like security and speed has made this technology a boom over Wi-Fi. Both Li-Fi and Wi-Fi works on Electromagnetic spectrum for the transfer of data. But Li-Fi uses visible light region whereas Wi-Fi uses Radio Waves for communication. Many Researchers have been currently working on this...
Significant growth in number of smartphone users and applications running on them has been observed in recent decade. The applications require diverse amount of data bandwidths based on their interactivities. Data hungry applications demand huge plan whereas a background application is satisfied with a minimum amount. Thus, smartphone applications should be allocated their required budget in such...
Multimedia content transfer over the internet is becoming increasingly important with a large penetration of smart phones PDAs, Laptops and IPTV. The interfaces supporting real-time applications such as Tele-education, entertainment, tele-medicine, remote monitoring and control are consuming a lot of bandwidth. All these applications require reliable streaming of the data over the internet, adhering...
In recent years, Multipath TCP [1] has been extensively studied. However, it has been mainly studied for the purpose of bandwidth aggregation or smooth failover during roaming within mobile networks. Interactive real time data for the control of machines is a special case in data transmission as failure tolerance and latency are the important Quality of Service (QoS) parameters. In order to establish...
We explore the relationship between regime type and country access to the Internet at both domestic and global levels by conducting longitudinal analyses of economic, population, and Internet data between 2002 and 2011. In particular, we investigate how a country's position in the global Internet network is associated with the country's type of political institution while attempting to take into account...
Video traffic shares a large portion of the current Internet bandwidth. One of the objectives of designing Named Data Networking (NDN) is to reduce the burden of the large content delivery. Since mobile devices are the prime means of content access for many users, NDN is also required to support mobility. In this paper, we propose an architecture and mechanism called On-Path Resolver Architecture...
We consider the problem of distributed rate adaptation among multiple video streaming sessions over the Internet from a decision-theoretic and computational intelligence point of view, and we design a multi-objective optimization model for network resources, seeking a fair and efficient distribution of end-users' Quality of Experience (QoE). A social welfare function is developed to capture both fairness...
Communication infrastructures under the influence of the disaster strike e.g., earthquake, will be partitioned due to the damage of components such as base stations. The communication model of the Internet bases on a location-oriented ID, i.e., IP address, and depends on the DNS (Domain Name System) for name resolution. Therefore such damage remarkably deprives the reachability to the information...
After several years of research towards sophisticated QoS measurement tools and methods, the results given to endusers by most commonly used on-line speed measurement tools are still far from being precise. In order to define a reliable Internet speed measurement methodology for endusers, the impact that the static and dynamic constraints of network nodes and TCP/IP implementations could impose must...
BGP control mechanism has been offered to be engaged with the existing inter-domain routing protocol (BGP) to be able to fulfill and manage the internet scalability demands of bandwidth, services, applications, technologies and off course users.
The evolution of Internet access technologies, together with the wide diversity of customer devices, has led to a complex scenario where measuring basic metrics with accuracy has become a rather complicated task. Although nowadays there are a lot of tools to assess the rate of Internet speed, most of them share neither the methodology nor the infrastructure to produce comparable results. In this regard,...
Web caching has been used extensively to enhance web delivery to clients by minimizing the latency perceived by clients, reducing network bandwidth usage, reducing power consumption and improving the network quality of service. Caching performance can be improved by implementing an efficient replacement policy to be used for proper cache replacement. In mobile networks, the movement of users presents...
Caching is a core problem in Information Centric Networks (ICN) which can be considered as a network of caches. The design of effective caching algorithms involves a broad range of interrelated problems such as how to accurate predict the requests, and how to optimize cache replacement. In this paper, we develop a lightweight caching management algorithm motivated to maximize the traffic volume served...
The Content-Centric Network (CCN), as a promising communication architecture for future networks, is still facing many challenges. In CCNs, it is difficult for the routing protocols, evolved from the proactive routing protocols in the current Internet, to discover temporary content replicas spread in router caches in time. This paper proposes a perceptive forwarding strategy (PFS) to perceive closer...
Internet applications are deployed on the same network infrastructure, yet they have diverse performance and functional requirements. The Internet was not originally designed to support the diversity of current applications. Network Virtualization can enable heterogeneous applications and network architectures to coexist without interference on the same infrastructure. Embedding a Virtual Network...
Broadband network performance is multi-faceted: it varies by ISP, by content source, by household connection, and by time-of-day. Daily or monthly averages, as published by content providers such as Netflix and Google, do not convey the full picture. In this paper we leverage M-Lab, the world's largest open measurement platform, to characterize broadband performance across Australian households. Our...
While Internet traffic is currently dominated by elastic data transfers, it is anticipated that streaming applications will rapidly develop and contribute a significant amount of traffic in the near future. Therefore, it is essential to understand and capture the relation between stream and elastic traffic behavior. In this paper we focus on developing simple yet effective approximations to capture...
