TCP and UDP are two important protocols in the network transport layer. In this paper, we study the effects of TCP and UDP on the performance of the application. Based on OPNET simulation software, a simple FTP application simulation model was created and the experiment was carried out. In order to test the influences of different transport protocols on the performance of application in different...
With the evolution of the current use of the Internet and the volume of content exchanged through the web, huge datacenter networks (DCN) are deployed to take into account the diversification and mass of contents. In these datacenters, the architecture is an important component that has a great impact on its performance. In addition, the communication inside them is usually IP-based, which has been...
Packet-based mobile networks are increasingly carrying internet traffic mostly for data intensive-applications. Mobile internet usage, with 67% share worldwide, is very important for mobile users. Because of the explosive growth of mobile data usage demand, data speed analysis is a very essential way to characterize network quality and user experience for service providers. Key Performance Indicators...
Depending on the congestion level and the network characteristics (e.g., buffer sizes, capacity of the bottleneck, deployment scenario, etc.) a fixed Initial Window (IW) would be either too conservative or too aggressive. This results in low usage of the network resource or damaging high congestion level. This paper presents a sender-side only modification to the slow-start of TCP, SmartIW, that bypasses...
The growing demand for video streaming is straining the current Internet, and mandating a novel approach to future Internet paradigms. The advent of Information-Centric Networks (ICN) promises a novel architecture for addressing this exponential growth in data traffic, with ubiquitous caching to facilitate video delivery. In this paper, we present a novel in-network video caching policy in ICN, named...
In last decade, number of internet users are increasing so as Wi-Fi network usage is also increasing. Users are using Wi-Fi network for the internet facility. Wi-Fi network is a collection of Mobile Users [MUs] and Access Points [APs]. Because of unavailability of smart association techniques, sometimes mobile users are associated to single access point beyond the capacity of the access point, at...
By large tsunami damage due to the Great East Japan Earthquake, many existing network system stopped functioning in various factors. Even under such circumstances, some of the information communication method that including satellite communications, it was able to recover the Network Connectivity, actually quickly and effectively. Although there are some valid information communicating method in disaster,...
Broadband Internet user base is growing at an exponential pace in India. The market pressures are forcing the Internet service providers (ISPs) to sell their service offerings aggressively, resulting in a growing discrepancy between consumer expectations and service offerings from the ISPs. This discrepancy is often evident in experienced vs offered Internet connection service. We study the Quality...
The Tor network is currently by far the most popular system for providing anonymity on the Internet. Even though both latency and throughput have been significantly improved in recent years, Tor users still experience variable delays on connecting to servers. Such delays have been shown to be especially harmful for browsing the web and prevent altogether the use of protocols where a certain quality...
In this paper, we introduce an experimentation of V2X communication in real environment for a road alert information sharing system. Traffic accidents and traffic hazard are serious social problems. Understanding road condition in advance is important and necessary to prevent traffic accidents and traffic hazards. In addition, getting information without Internet connection is necessary to provide...
This work describes a cross-layer resilient protocol stack for survivable network communications during regional challenges. The GeoDivRP routing protocol collects network statistics and calculates multiple geodiverse paths; it provides these geodiverse paths upstack to the resilient transport protocol, ResTP, for resilient multipath communications. ResTP provides multiple resilience modes to cope...
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...
Application-defined and location-independent addressing is a founding principle of information centric networking (ICN) that is inherently difficult to realize if one also wants scalable routing and forwarding. We propose an ICN architecture, called TagNet, intended to combine expressive application-defined addressing with scalable routing and forwarding. TagNet features two independent delivery services:...
IoT has emerged to realize the notion of ubiquitous interaction of everything. With the help of IoT, various types of objects including human, machine, and almost all things can communicate with each other via the Internet. However, the current state of the art in IoT technology focuses on the limited application such as signalling and exchange of sensing data. In this paper, we look into the necessity...
In this paper we experiment and analyze the Multipath TCP (MPTCP) proposed by Internet Engineering Task Force (IETF). The authors consider MPTCP offerings such as multipath aggregation, increased throughput, enhanced resilience, network handover and employing various congestion control algorithms over multipaths to aggregate available bandwidth as key factors to assess experiments with various topologies.
Recent development in communication of wireless communication for automobile industry have aided the growth of ITS (Intelligent Transport System) which solves numerous vehicular mobility concerns like traffic congestion, accidental mishap etc. VANET (Vehicular Ad-hoc Network) a characteristic class of MANET (Mobile ad-hoc Network) which is a fundamental element of Intelligent Transport System in which...
In this paper we present a novel approach to optimize and regulate performance in a multitier server. By using a queueing network model, we optimize the values of the mean service rates at each tier in the server by applying randomized algorithms based on statistical learning theory. After the optimization process is carried out, an IPA algorithm is implemented to regulate the throughput of the system...
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...
We are developing multi-hop wireless LAN access points (APs) for a Community Information Network (CIN) to be deployed in Takanawa area, Minato City, Tokyo, Japan, to transfer information supporting citizens' daily lives and to provide the internet access environment for both residents and tourists. This paper shows a prototype development of the AP device for the CIN made by the Raspberry Pi boards...
