The connection-oriented nature of wireless access has been setting limitations to accessing Internet services. In particular, Internet access via public Wi-Fi infrastructure typically requires a subscription and a complicated authentication procedure that can hinder connection establishment, according to recent reports. In this respect, we present FreeSurf, an architecture for turning existing wireless...
In dense deployments of residential WiFi networks individual users suffer performance degradation due to both contention and interference. While Radio Resource Management (RRM) is known to mitigate this effects its application in residential WiFi networks being by nature unplanned and individually managed creates a big challenge.
This paper discusses on the need to focus on effective and cheap communication solutions for the deployment of smart services in countrysides. We present the main wireless technologies, software architectures and protocols that need to be exploited, such as multihop, multipath communication and mobility support through multihoming. We present Always Best Packet Switching (ABPS), an operation mode...
802.11 (WiFi) networks have become increasingly important for our daily lives. However, previous work has shown that enterprise WiFi performance is often unsatisfactory and that over-utilization and interference from rogue APs are the two primary reasons. To address the above problem, this paper proposes to improve the capacity of WiFi infrastructures by increasing the enterprise AP deployment density,...
MobilityFirst (MF), as a realization of Information Centric Network architecture, places intelligent functionality, such as storage and reliability, inside the network to assist with data delivery. The MF architecture requires effective congestion and flow control to efficiently support data delivery at scale. Traditional end-to-end, window-based congestion control like that used by TCP is unsuitable...
This study is the evaluation of the performance of the Wireless Local Area Network (WLAN) 802.11n, implemented in the Faculty of Engineering, Islamic University of Riau. The study in the wake server E Learning and will be accessed using the Wireless LAN 802.11n. This simulation uses Riverbed Software Modeler and study a simulation to estimate the number of web user clients and other network applications...
Use of FPGA's in robotics gives us lots of option to solve the complex operations and real time applications as well. The speed and reconfigure ability of FPGA make that possible. Wireless communication which is having tremendous applications, we are making the use of wireless communication along with FPGA to have industrial security as well as application. The implementations of such a system will...
This paper introduces the Ghana Technology University College (GTUC) television white space (TVWS) network deployed in Accra, Ghana. The network, which is still work-in-progress, provides broadband Internet connectivity to six Senior High Schools and the GTUC-Abeka campus using two sub-networks built using White Space devices from two different manufacturers. After introducing the GTUC TVWS network,...
Demand on the existent frequency spectrum increases by the development of the wireless communication technologies. Dynamic Spectrum Access (DSA) is a concept that should be a solution for this demand. This concept consists of to find and serve into use the frequency bands that licensed wireless communication systems don't use as a purpose also. From the beginning of 2000's, primarily in US later in...
A Community Network is a bottom-up network created by a community of people with the goal of building a self-owned, self-managed communication infrastructure. Community Networks are blooming, they range from small ones (tens of nodes) to gigantic ones (tens of thousands of nodes), they are made primarily of wireless links but in some cases they mix wired and wireless technologies. People running a...
In this paper, we present a new authentication architecture for Taiwan High Speed Rail (THSR). The new authentication architecture applies multiple outbound LTE gateways. We also propose an SDN-based authentication method using post-authentication that is suitable for high-speed environment, including THSR. The proposed architecture and method can reduce network congestion and shorten the authentication...
This demo presents Oi!, an opportunistic data transmission tool. Implemented on Android and available as open-source, Oi! relies on social interaction, device-to-device short-range wireless transmission, as well as on history of contact duration to perform opportunistic data transmission. In this demo we show how Oi! can be used with intermittent Internet access between sources and destinations, to...
Powered by next generation mobile networking capabilities, the Tactile Internet will be able to transport touch and actuation in real-time. Enabled by suitable robotics and haptics equipment at the edges, and an unprecedented communications network, the Tactile Internet will provide a true paradigm in creating skill-set delivery networks. The fifth generation (5G) mobile communications systems will...
Advances in wireless communication devices and systems have a significant impact on various fields like agriculture, healthcare, smart homes etc. One of its important applications is the development of monitoring system for various purposes. Automated water usage monitoring system proposes an effective way of controlling the wastage of water at home/Industries by means of Wireless sensor nodes and...
The immense development in mobile devices and the proliferation of ubiquitous cloud-based services have led to a surge in the utilization of remote data centers. These dramatic advances in wireless based services induce a huge traffic flow within the network. However, consequent high load on the network devices may lead to faults and thus an adverse decrease in the user experience. On the other hand,...
TV White Spectrum utilization has become a major concern in the field of communication sector throughout the world. This research paper focuses on utilizing the TV White Spectrum for Wireless Broadband Internet Connectivity (WBIC) on the basis of availability. For reference, a practical scenario has been considered. The scenario represents the TV White Spectrum of Bangladesh Television (National Television...
Communication technologies of the Tactile Internet have to achieve a combination of extremely low latency under high reliability and security constraints. The targeted applications are in the fields of industry automation and transport systems, healthcare, education and gaming. 5G addresses tactile use cases under the term mission-critical machine type communication. We demonstrate a first implementation...
Named Data Networking replacing the TCP/IP architecture has emerged as a state-of-the-art tendency in VANETs because of its high efficiency in content distribution and Vehicle-to-Vehicle (V2V) communications. After this paradigm shift in VANETs, the traditional gateway selection algorithms and Peer-to-Peer content downloading protocols become inappropriate for vehicles to cooperatively acquire big-size...
The Tactile Internet will be able to transport touch and actuation in real-time. The primary application running over the Tactile Internet will be haptic communications. Design efforts for both the Tactile Internet and the haptic communications are at a nascent stage. It is expected that the next generation (5G) wireless networks will play a key role in realizing the Tactile Internet. On the other...
