Rogue access points (RAPs) are unauthorized devices connected to a network, providing unauthorized wireless access to one or more clients. Such devices pose significant risk to organizations, since they provide a convenient means for hackers and insiders to hide malicious or unsanctioned activities on industry, government, and campus networks. Yet, limitations inherent in traditional networks make...

Research in recent years have led to the emergence of technologies for remote monitoring of patients with the wireless transmitted to biomedical signal obtained from various sensors. Specialist person who monitors can be connected via a router to the IP address of the wireless board monitoring system, and through software developed in LabVIEW graphical programming software can read the value of measuring...
Software Defined Networking (SDN) and OpenFlow represent the most commonly deployed approaches of the so called Programmable Networks. SDN is an emerging network architecture, which performs the subdivision of control plane and data plane and allows greater speed, greater scalability, and greater ductility in terms of routing and forwarding. OpenFlow, instead, is an SDN component that characterizes...
This paper presents the design and prototype implementation of new Wi-Fi technology based monitoring and controlling the field equipments or machines using Phone, Tablet Laptop or any desktop pc having Wi-Fi utility with IEEE 802.11b, g and n standards.
Smart environments are places where different kind of embedded devices are interconnected in order to provide their occupants intelligent services improving their comfort and convenience. These smart environments are seen to be important for the future urban ecosystems in terms of user friendliness, quality of life, energy efficiency and sustainability. Lately such environments have become economically...
Current maritime on-board communications have to be enhanced for safety and security, where ubiquitous technologies can help, together with providing comfort and convenience to the crew and passengers. Employing wireless sensor networks on board is one recent practice of implementing ubiquitous technology for ships, where further study is needed because of the connectivity challenges. Meanwhile, it...
Mobile ad-hoc networks (MANETs) are autonomous distributed networks, where mobile nodes communicate with each other using wireless links. Since the communication is done by wireless links, it is difficult to grasp the network situation. It becomes even more difficult when the number of nodes is increased. In this paper, we propose a visualization system for MANETs. The system can mainly visualize...
This paper deals with the design of a Modbus Enabled Zigbee Wireless Sensor Network “WSN” for better Interactive Industrial Automation. The Modbus protocol is embedded into Zigbee stack, providing a friendly interface to observe the information in the wireless network efficiently and to provide the On Demand Response to the requests. It consists of a Coordinator and the sensor nodes. The coordinator...
General packet radio service (GPRS) is a packet oriented mobile data service on the 2G and 3G cellular communication systems global system for mobile communications (GSM). GPRS is the most widely used technology solutions to solve mobile communication combined with IP. Due to its advantage such as real-time online, binding billing, quick login, high-speed transmission, widespread coverage etc, it...

As more network-capable devices are developed, it becomes easier for us to remain connected to our friends, colleagues, and even our homes. Unfortunately, it becomes easier for unintended third parties to remain connected to us as well. The impact of this has been limited by our proximity to the third party (i.e. the same local area network) -- until now. The Internet Protocol version 6 (IPv6) includes...
In the remote, hazardous, distributed and external environment, such as radiation source, pollutant source and pipeline of petrol, water and gas, it is difficult to collect and send the necessary message in real-time by traditional monitoring ways. This paper briefly describes the design of remote wireless monitoring system based on MCU (Micro-programmed Control Unit) and GPRS (General Packet Radio...
