For wireless networking standards which aim for remote control and sensor application in radio environments and isolated locations can be achieved by ZigBee. The shorter range of connectivity can be achieved by Bluetooth and it is wireless. In this article we motivate the need to learn and understand about various new technologies like ZigBee and Bluetooth. Further, we get detailed knowledge about...
The use of wireless technology has permeated every sphere of our lives and across all cross sections of society. Whether it is at the personal level or for the public good, wireless technology has evolved over the years to provide efficient systems to improve the quality of life on the planet. While there are a host of wireless technologies available today catering to applications in the Medical Field,...
Since 2005, Smart Grid technology has revolutionized the electric power system industry. Researchers have shown a lot of interest in the opportunities offered by ICT(Information and Communication Technologies), to modernize the operation of electrical networks. This is possible by decarbonizing them as well as monitoring and controlling them with sophisticated communication standards. For this purpose,...
Positioning is the foundation of wireless sensor applications. An attack method of multiple counterfeit identities in sensor network localization is proposed. At different times, attack nodes counterfeit different identities nodes, sending false reference coordinates, which leads to the failure of positioning. In the paper, we establish a normal localization system, which can accurately calculate...
Smart wireless home security technique is one of the emerging technologies for intelligent building surveillance. Many wireless technologies like Bluetooth and Wi-Fi have been used in this regard. In this paper we have proposed a Smart and Contemporary Home security system using low cost, low power Zigbee (802.15.4) standard. The Zigbee uses multi-hop communication for data transfer. The architecture...
Security will be critical for the wireless interface offered by soon-to-be-ubiquitous smart meters -- since if not secure, this technology will provide an remotely accessible attack surface distributed throughout many homes and businesses. However, history shows that new network interfaces remained brittle and vulnerable (although believed otherwise) until security researchers could thoroughly explore...
ZigBee, Wibree, Z-Wave, and RuBee are four protocol standards for short range wireless communications with low power consumption. From an application point of view, ZigBee is designed for reliable wirelessly networked monitoring and control networks, RuBee is proposed for high security applications and use in harsh environment, Wibree considered for sports and healthcare while Z-Wave is planned for...
The current state for security research in sensor networks presents many approaches for all possible security services. Upon network deployment protocols must be selected and made to work together so that they meet application requirements like security level, dynamics or power consumption. This is a non-trivial process and requires an expert in both security and networks, and can definitely not be...
Bluetooth, ultra-wideband (UWB), ZigBee, and Wi-Fi are four popular wireless standards for short-range communications. Specifically, ZigBee network is an emerging technology designed for low cost, low power consumption and low-rate wireless personal area networks (LR-WPAN) with a focus on the device-level communication for enabling the wireless sensor networks. In this paper, after a brief overview...
In this paper the need of sensors other than analog and digital cameras in a CCTV environment are discussed as well as the advantages these security relevant sensors can offer. After evaluating various use cases the currently available technologies in this area will be analyzed including Bluetooth, Zigbee and Wireless USB. The main focus will be placed on the security aspects, the behavior in case...
Nowadays, smart home using wireless communication is replacing the wired system which was very messy and difficult to setup. However, the existing wireless smart home system only can cover up to a certain range of area that is limited by the range of wireless module being used. This paper introduces the conceptual understanding and strategy of ZigBee IEEE 802.15.4 standard to be deployed in smart...
Wireless sensor networks consist of a large number sensors spread across a given geographical area. Each sensor has its own communication capability as well as certain level of intelligence for signal processing and networking. As the sensor nodes are densely populated, communication range requirement for these nodes is smaller. After signal detection, a number of sensor nodes communicate over the...
