In this paper, we discuss the singular characteristics of the Internet of Things (IoT) in regard to security issues and present a security architecture with special focus on Edge networks and Smart Things. The architecture is based on the assumption that data integrity, authentication, and service/device access control are the most important aspects that have to be guaranteed for safe operation of...
Low-Power Wide-Area networks promise to deliver limited IoT payloads reliably at distances in excess of 10 km raising the possibility of thousands of IoT devices connected to a single base station. PlanIt is a web application able to visualize connectivity in these large-scale deployments prior to deploying hardware or even making a single signal-strength measurement. DQ-N is an adaptation of distributed...
Delay tolerant networks (DTN) are characterized by lack of end-to-end communications and stable infrastructures. This paper deals with DTN networks consisting of a number of heterogeneous mobile fishing vessels where some nodes, referred to as adaptive nodes, are capable of communicating through long-range Wi-Fi whereas other nodes are having simple Wi-Fi access network. The nodes form different clusters...
The next generation networks is based on packet switching which involves voice, data and multimedia such as audio and video. It provides fixed mobile convergence to all valued customers. The 8 core exchanges in India is now commissioned and about 136 core switches have started to work. The BSNL has planned a huge network wherein all the traditional voice and data customers migrate from C-Dot TDM towards...
A Vehicular Cloud generally focuses on several aspects, which include providing a set of computational services at low cost to vehicle drivers; minimizing traffic congestion, accidents, travel time, and environmental pollution; and ensuring the use of low energy and real-time services of software, platforms, and infrastructure with QoS to drivers. The largest challenge in vehicular mobile Clouds consists...
Nowadays the widespread use of variety of smart phones and tablets with wide range of multimedia application support is driving more data service users towards full mobility causing a rapid increase in demand for mobile data rates. These new devices and multimedia applications require high data rates and reduced latency to provide better Quality of Service (QoS). To address these requirements the...
This paper is concerned with the analysis of connecting PROFIBUS with 4G mobile network to realize the application of 4G in the field bus. First, development status and technical characteristics of PROFIBUS in the industrial network are analyzed, including the requirements of PROFIBUS Fieldbus for wireless communication systems in the intelligent and networking development. Then, the authors introduce...
Smartphones are overpowering the IT world by rising as a prerequisite for other technologies. Emerging technology paradigms such as Cloud computing, web data services, online banking and many others are revamping them as compatibility to smartphones. Banking is a vital and critical need in daily life. It involves routine financial transactions among sellers, buyers and third parties. Several payment...
The growing data traffic demand is forcing network operators to deploy more base stations, culminating in dense heterogeneous networks that require a high-connectivity backhaul. This scenario imposes significant challenges for current and future cellular networks, and Software Defined Networking (SDN) has been pointed as an enabling technology to overcome existing limitations. This paper shows how...
The dynamic composition of virtualized network functions promises to ease the introduction of new services in mobile networks, while reducing provisioning costs. This approach, usually called Service Function Chaining, has been the focus of several research efforts. However, current systems rely on new tunneling protocols and on network infrastructure changes. In this paper, we introduce CATENAE1,...
In this study, we propose a method for improving the scalability of sharing the flow rules, which are used to inspect and direct packets, between gateway functions in a mobile network virtualization infrastructure. The proposed method enhances the centralized management mechanism, where a controller reactively installs rules based on receiving the first packet of each flow, to reduce the load in the...
In a mobile IoT system, IoT devices are located in a moving vehicle such as in a car, in a mobile robot or in an Unmanned Aerial Vehicle (UAV). An IoT Gateway aggregates data from various IoT devices located in a moving vehicle and its surroundings. This GW could also be located in the vehicle itself. We consider infrastructure as well as ad-hoc mode scenarios here. In infrastructure mode, this mobile...
Introducing an IP-based communication system into the mountain rescue domain would enable carrying out search and rescue missions in an effective way. With efficient mobility and multihoming support, a Mountain Rescue Team would be able to establish more effective and reliable Internet communication. In this paper, we present the Multihomed Mobile Network Architecture (MMNA), a comprehensive multihomed...
As the important part of the virtual application system, the remote control software plays an important role in the interaction between system and user. With the rise of mobile Internet, the virtual desktop software which runs in PC has been very difficult to adapt to the demand for mobile communication. This paper mainly introduces mobile virtual application, which based on the Remote Desktop Protocol...
The number of networked smart devices available in everyday environments is rapidly increasing; however, many current devices adopt mutually incompatible networks, protocols, and application programming interfaces. As such, creating mobile applications that dynamically discover and integrate ambient functionality across multiple vertical markets remains challenging. In this paper, we introduce a novel...
The use of centralized signal processing for dense urban mobile networks is gaining interest both in research and in industry. Gathering most of the base station functionalities in a processing pool would enable capacity sharing and the implementation of advanced techniques such as coordinated multi-point. Nevertheless, this puts stringent requirements on the network interconnecting the processing...
Micro-blogging in Mobile Social Network can be very successful because of spatiotemporal properties of user interests and generated messages. Users can follow their interests and receive messages of their interests without getting overwhelmed instead of having to identify and follow users having similar interests. We propose a distributed and scalable micro-blogging protocol which exploits community...
IP mobility ensures network reachability and session continuity while IPv6 networks are on the move. In the Network Mobility (NEMO) model, the potential for NEMO Mobile Routers (MRs) to interconnect and extend Internet connectivity allows the formation Nested NEMO networks. With MANEMO, nested MRs can be efficiently interconnected in a tree-based structure with Internet access being maintained via...
Smart Objects and Smart Environments are expected to become two of the leaders of the future Internet of Things. In this context, the Smart Homes are getting more and more attention, since people are very attracted by the idea of a home environment able to automatically meet their needs. However, the heterogeneity of the smart devices, the difficulty in automating the user-home interaction, and the...
