One of interesting problems, arising with deployment of large-scale systems, is integration of its nodes (systems / devices). In this work, we discus how to apply semantic technologies, as a mechanism to support node integration and facilitate interoperability within the developed ecosystem. We focus on pragmatic aspects of the proposed solution, discussed from the perspective of the Dependable Embedded...
A distributed system is presented for the monitoring and control of the primary variables: pressure, level and flow; for this, a wireless system is implemented at the level of sensor-actuators and at the level of controllers an Ethernet / IP network, the mentioned industrial networks are implemented based on the OSI model and TCP / IP respectively, for the visualization an HMI is realized in the software...
Internet of Things (IoT) depicts an intelligent future, where any IoT-based devices having a sensorial and computing capabilities to interact with each other. Recently, we are living in the area of internet and rapidly moving towards a smart planet where devices are capable to be connected to each other. Cooperative ad-hoc vehicle systems are the main driving force for the actualization of IoT-based...
This paper presents a wireless intrusion prevention tool for distributed denial of service attacks DDoS. This tool, called Wireless Distributed IPS WIDIP, uses a different collection of data to identify attackers from inside a private network. WIDIP blocks attackers and also propagates its information to other wireless routers that run the IPS. This communication behavior provides higher fault tolerance...
As mobile broadband (MBB) technologies evolve, devices need to support increasing bandwidth with multiple frequencies and dramatically exploding data rates. New air interfaces in 5G will show once again the gain in data rates as we have seen from 2G, to 3G to HSPA, to LTE and LTE advanced. These technologies in a single device provide the best possible services with great user experience to all people...
Communication is one of essential elements of our life. In some cases, we need wireless links to support data transmission such as television relay. But the existing GPRS and other network often need the support of power transmission line. And in the remote areas, the transmission rate of traditional network is very slow. In this paper, the development and realization of wireless self-organization...
This paper details the design and development of IoT based security surveillance system in buildings using Raspberry Pi Single Board Computer(SBC) with WiFi network connectivity. Adding wireless fidelity to embedded systems will open up various feasibilities such as worldwide monitoring and control, reliable data storage etc. This system comprises of wireless sensor nodes and a controller section...
In order to further education in embedded discovery, Protomesh (prototype mesh) seeks to improve the field by providing a wireless solution for deploying Raspberry Pi workshops. Protomesh is a platform for starting up a quick ad-hoc batman-adv network. Batman-adv is an open source, kernel module native to Linux that provides a layer two mesh network routing protocol [2]. We leveraged this technology...
Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT) is an integral part of Orthogonal Frequency division multiplexing (OFDM) systems. This forms the physical layer architecture of wireless systems and is designed to consume low power. This paper presents a low power and area efficient architecture for the FFT implementation. FFT involves more complex addition and multiplication...
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...
Autonomous drones system has great potential in robotics research and it is used in industrial applications. One of the popular examples is Amazon Prime Air service which uses drones to delivery customers ordered products. Another example is under indoor environment such as transferring goods and products in warehouse. However, there is a research challenge when implementing - autonomous drones system...
In this paper, we investigate the optimization of the power splitting factor and the relay selection problem in two-way full-duplex (FD) relay networks, where the relays are wirelessly powered by harvesting a portion of the received signal power from the sources. To the best of the authors' knowledge, this is the first time that the two-way FD relays with simultaneous wireless and information transfer...
Modern Smart Home Automation (SMA) systems are predominantly based on wireless communication standards. New home automation setups can often include dozens of devices ranging from thermostats, humidity sensors, light switches, digital locks and cooling systems, all communicating on a common network. In this paper we focus on how SMA systems built on one of the most common standards (Zigbee), could...
The Intelligent Power Switch (IPS) allows to control the energy flow in a residential electric distribution system and decreases intermittency that the integration of Renewable Energy Sources produces in a power grid. This paper presents the simulation analysis of different commutations' scenarios in the IPS to identify current and voltage characteristics in sources and loads. In addition, the use...
Over the last few years the number of mobile nodes connecting to the Internet over wireless networks increased considerably. Mobile nodes want to roam freely and always be connected to the Internet. Unfortunately the current IP architecture is not designed for end-to-end mobility because of the overloaded semantics of the IP address. This dual role hinders mobility. As a result Locator Identity Split...
This paper presents a compact, ultra-low power AES-CCM authenticated encryption IP core for WBANs by combining a low area 8-bit AES encryption core, iterative structure and other optimized circuits. The proposed AES-CCM IP core can be used for the message security at the MAC level, e.g. message encryption and authentication, based on AES forward cipher function with a 128-bit key for counter and cipher...
Residents fueled gas network transfer data to master station by adopting GPRS network at present, but the situation of communication for residents fueled gas network is complicated and displays the unsteady signal for GPRS, slow rate for communication, make the communication between gasometer and master station often at the interrupted situation and brings uncomfortable condition to the operation...
The coexistence and overlap of the different wireless networks available nowadays can be beneficial for mobile nodes. Whenever a better network/service provider is available, handover may be preferred. Wireless networks might differ in characteristics like IP network address, radio access type, supported services, coverage area, bit rate and cost. Users might like to apply certain preferences to handover...
This paper introduces the Distributed NFV Orchestrator (DiNO). DiNO integrates and orchestrates Software-Defined Networking (SDN) and Network Function Virtualization (NFV) in a physically and logically distributed manner and optimizes their service quality and resource utilization. In the DiNO architecture, Virtualized Network Functions (VNFs), including servers, middleboxes, and QoS, can be dynamically...
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.
