The revolutionary network that totally changed how the humankind life, the Internet, is now evolving into the Internet of things; which is being achieved by fetching the network connectivity to legacy industrial or commercial devices, as well as everyday objects. This connectivity may be an Internet connection, where the Internet protocol and related technologies are in use. But, there are also many...
Ad-Hoc and Delay-Tolerant Networks (AHDTNs) can be very useful in environments where more traditional networking technologies fail. Determining the practical effectiveness of AHDTNs can however be challenging. We review design considerations and practical experience with a novel mechanism for monitoring and analyzing the performance of AHDTNs. This new mechanism, AllNet Trace, somewhat resembles a...
Internet connection is essential for daily life, however not all areas are covered by Internet access due to historical reasons. For example, with 3.7 million daily passengers, London underground system has no WiFi or cellular signal provided during travelling due to legacy reasons. Deploy new access infrastructure need to consider the integrating problem with the current environment, also bring a...
With the rapid development of new applications and services in vehicular environment, there is an increasing demand for mobile users to access data items. Moreover, Road Side Unit (RSU) has been introduced by researchers to facilitate data dissemination in Vehicular Ad-hoc Networks (VANETs). Therefore, it is necessary to design a data access scheme for vehicle-to-roadside (V2R) communications. However,...
IVANETs (Internet Based Vehicular Adhoc Networks) are the adhoc networks formed by moving vehicles without any permanent infrastructure and are characterized by frequent disconnections, frequent topological changes, as vehicles move at very high speed and can take unpredictable turns on their route. So their cached data items become stale, need to be updated from the server and it results in high...
The fast topology changes in vehicular ad hoc networks (VANETs) may be caused by fading of the wireless link as well as mobility of nodes. Link stability is often measured using mobility parameters (e.g, location, velocity, direction), and disregarding multipath fading of the signal. This may cause network performances degradation. In this paper, we have improved the relay selection scheme by integrating...
Internet Protocol version 6 (IPv6) is presently gaining demand in almost every region of the world. In near future, IPv6 would be the key area of research and expansion in the internet protocol standards. IPv6 was built with the aim of improving the mobility and communications among these devices. Mobile IPv6 is becoming a highly demanding research area under which a lot of investigations are yet...
During a disaster incident, existing network infrastructures might either be damaged or overloaded. However, disaster operations require real-time and low latency data communication, especially live video and audio streaming, as well as in integration with social networks. Thus, deployed tactical networks face several challenges to connect intervening teams. To date, there is still a lack of routing...
The recent development in the large domain of theInternet of Things is driving conventional change in Vehicle AdhocNetworks, now known as Internet of Vehicles (IOV), Vehicleto-Vehicle (V2V), Vehicle-to-Infrastructure(V2I) and someIntelligent Transport System (ITS) applications will require verylow latency, much lower than is currently provided by existingcommunication networks. The connected vehicles...
In the high-speed train, passengers want infotainment services which provide users with useful information about the area they are passing by, or information about their destination. This paper introduces dynamic SNS for train application which enriches user experiences with ad-hoc group chatting, contents sharing, recommendation based on user preference and location, and train environment information...
In this paper, we propose an ad-hoc communication system for a smartphone, which utilizes Bluetooth Low Energy (BLE). The proposed system is assumed to be used in disaster situation where the Internet connection is not available. It means that a smartphone cannot obtain any information as well as any new application because all the applications are distributed in the cloud such as App Store. However,...
Named data networking (NDN) paradigm solves various issues of current TCP/IP based Internet and considers as a good candidate for future Internet architecture. It has a simple communication mechanism based on named contents instead of their physical locations. In NDN-based mobile ad hoc networks (MANETs), the participating nodes have limited resources. Interest message flooding is a key research issue...
Transmission of massive content over wireless mobile networks may not guarantee high quality content delivery due to insufficient bandwidth. To overcome this limitation, there is a growing interest in the complementary network, e.g., challenged network, to provide direct communication among the mobile devices. Such networks may suffer from high delay, low data transmission rate, and frequent disconnections...
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...
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...
Mobile ad hoc networks (MANETs) are self-configuring, dynamically adaptable networks of heterogeneous devices, some of which can assume the role of routers. Meanwhile, mobile computing is an increasingly pervasive technology worldwide, thus positioning MANETs as a very suitable technology for disaster scenarios. This article addresses the problem of guaranteeing a minimum operational infrastructure...
Wireless Sensor Networks are widely used in various applications like maintenance of ecosystems, in militaries, hospitals, etc Also WSNs are used with the data gathering methods to enhance the resources and energy which lack in some performance parameters. So here, we are combining the concept of ferry to the WSN. In general, ferries are small commutator boats which carry or take the peoples from...
The project aims to provide communication anywhere anytime when the telecommunication network is not available for example after a disaster, or in sparsely populated areas. Mobile phones normally can't be used when cellular networks fail as in case of disaster. This means that millions of people around the world are not able to communicate, when they need it most as most of its functionality are supported...
A multichannel wireless mesh network is composed of wireless routers with multiple radio interfaces operating on non-overlapping channels. It provides a network backbone to support multi-hop connectivity between wireless users and the Internet gateways. However, robustness is a critical issue in such networks because wireless links could be prone to error. Simulation results show that the proposed...
In the last couple of years Software Defined Network (SDN) have come into existence which empowers network operators with more flexibility to manage and program their network. This type of network solves the limitation of legacy networks. Data plane and control planes are separated from each other as a result data plane devices simple act as a packet forwarding device and leaving the decision making...
