The problems associated with multipath routing in Border Gateway Protocol (BGP) for Autonomous Systems (ASes) can be solved with some model or control systems from the Software Defined Networking (SDN). The SdN controller could be used to solve the inconsistencies in the scalability and latency of the Routing Information Base (RIB) of ASes. Also, a set of modules for Inter-AS routing and Brokering...
The Extensible Messaging and Presence Protocol (XMPP) is one of the most popular Instant Messaging (IM) protocols which uses a client-server working mode. This protocol uses different connection primitives for both client-to-server (c2s) and server-to-server (s2s) connections. It is actively used in mission-critical operations where the reliability and security of communication systems is always imperative...
Topology control is a crucial process for an efficient operation of a Wireless Sensor Network (WSN). The usage of WSNs in the Internet of Things (IoT) emerges new research challenges and novel applications. Recent WSNs proposals enhanced with Software Defined Networking (SDN) practices introduce new innovative network control strategies and protocols based on central control logic. This paper introduces...
In this work, a method to design STIM for sensor network system is proposed. Hardware selects TMS320F28335 as main controller. A common software implementation method is also presented. Electronic spreadsheet and independent interface configuration is the key research points to realize hot-plug function. After testing, system can be used in electric transmission line leakage current and voltage detection...
Data centers availability is mandatory and is conditioned by a quick response to failures and attacks thanks to efficient live forensics. However, this task is lately impossible to complete with classic systems because of encountered data rates and service diversity. Moreover, Software-Defined Networking (SDN) devices agility requirements prevent the use of Application Specific Integrated Circuits...
Test Automation Platform©1 (TAP) is a software system that developers can use to test their own hardware or software (or combinations of both). Developers create TAP test plans by combining and configuring individual test steps in a GUI. Developers can also develop their own test steps with .NET to better suit their needs. Since (manual) programming is always prone to errors, TAP users need...
Distributed Denial of Service (DDoS) attack has been bringing serious security concerns on banks, finance incorporation, public institutions, and data centers. Also, the emerging wave of Internet of Things (IoT) raises new concerns on the smart devices. Software Defined Networking (SDN) and Network Functions Virtualization (NFV) have provided a new paradigm for network security. In this paper, we...
Making the data plane of a SDN flexible enough to satisfy the various requirements of heterogeneous IoT applications is very desirable for Software Defined IoT (SD-IoT) networking. The network device having programmable data plane provides an ability to add new packet and data processing procedures dynamically to the IoT applications. Previously proposed solutions for adding programmability to the...
Paper deals with the smart city and smart public lighting concept and their characteristics. Furthermore, it deals with public lighting management system capabilities and interoperability between more public lighting systems, with possibility of implementation of standardized system for public lighting management in terms of smart city concept. Different manufacturers of public lighting use a lot...
Mobile tactical networks (MTNs) in military communications extend the capabilities of mobile ad-hoc networks (MANETs). The MTNs are dynamic, infrastructureless, self-forming and self-healing systems designed for non-line-of-sight (NLOS) operations using multi-hop relaying. Unlike their commercial counterparts, MTNs have to offer much higher levels of security, jamming resistance, and service robustness...
This paper develops a supervisory control and data acquisition (SCADA) system to monitor an islanded DC microgrid including wind turbine, photovoltaics, and battery units. The SCADA system is based on KingView 6.55, and establishes data communication between the host and the slave computers through intelligent modules and different communication techniques. The developed SCADA system can monitor real-time...
This paper presents research results of industrial standard IEC 60870, presents design engineering data communications network using a standard for supervisor control system in electrical power engineering. The aim of the work is creation of realistic physical model multistaged network, quality level analysis this model and quality level analysis link protocol IEC 60870-5-104. Finally, article ends...
On the financial side, a key factor for the success of a smart-city initiative is the low cost of the sensors. On the technical side, the units need to be flexible enough to cover different roles, and to be reconfigurable for a distinct target. The capability to interact with an already deployed infrastructure, like a preexistent web-server, is a favorable feature from both the financial and technical...
Emerging protocols for low-power wireless networks increasingly exploit constructive interference and the capture effect. The basic idea is that the synchronous transmission of identical packets by neighboring nodes leads to constructive interference - or at least do not cause destructive interference. This requires that the temporal displacement of packets at receiving nodes is lower than 0.5 μs...
In opportunistic networks, forwarding based protocols lead to a large amount of data flow to the highly connected nodes and unfairness of the nodes' traffic load, finally, it makes the highly connected nodes suffer congestion and results in the messages were discarded. To solve this problem, a congestion control algorithm based on Social Awareness is proposed in this paper. When choosing the next...
Packet forwarding in Software-Defined Networks (SDN) relies on a centralised network controller which enforces network policies expressed as forwarding rules. Rules are deployed as sets of entries into network device tables. With heterogeneous devices, deployment is strongly bounded by the respective table constraints (size, lookup time, etc.) and forwarding pipelines. Hence, minimising the overall...
Social Media plays an increasingly important role in humanitarian and disaster response scenarios. However, typical social media applications rely on internet connectivity, and as a result are often not available during the acute phase of disasters. The MeshMS service of the Serval Mesh established the practicality of implementing a secure and private SMS-like textmessaging facility that can be used...
User story literature nearly exclusively studies how to create, prioritise, or ensure the quality of a user story. Little is known about other activities and artefacts involved preceding or following these activities in systems development. Consequentially, software teams seeking to leverage user stories’ full potential do not know how to incorporate user stories into all aspects of their software...
Being able to record and analyze data securely have a paramount importance to meet the needs of both military and civilian applications. Therefore, data acquisition systems are used to meet the needs of complex applications. A data acquisition system capable of data conversion, collection and transfer is described in this paper. This system is implemented on FPGA, because of high processing speed...
A tele-monitoring system, based on a soft transducer network, developed by students of the Course "Measurements on Communications Network" (MRC), at the Department of Electrical Engineering and Information Technology, University of Naples Federico II, is presented. This project is the result of an innovative education approach for (i) overcoming specialization of single Courses on different...
