The latest IEEE WLAN 802.11ad standard guarantees the multi giga bit throughput which is highest in the Wireless LAN (WLAN) technology. The system designed for such high performance will pose enough design challenges to make them consume low power. This can however be achieved by adopting low power management and control block in the digital part of the System on Chip (SoC) like Medium Access Control...
The paper presents simulation tools to determine battery lifetimes of different products for a complete RF standard home automation system based on KNX and Bluetooth Low Energy. 2D and 3D results allow studying various parameters of these RF protocols and the performances of the radio chips used.
Accurate network traffic classification is significant to numerous network activities, such as QoS and network management etc. While port-based or payload-based classification methods are becoming more and more difficult, Machine Learning methods are promising in many aspects. In this paper, we improve the standard Random Forest by setting the variable selection probability according to the importance...
This conference note describes a real-time tactical mobile network optimization agent (TNOA) utilizing real-time simulation. By modeling the wired and wireless links in near real time using the massively parallel, high performance network simulator QUALNET we optimize system performance via configuration control. Our heterogeneous tactical network consists of Link 16, Link 11, S-Tadil-J, and JREAP...
Smart Grid (SG) is becoming a reality in Brazil in many projects covering different areas such as smart metering, demand-side management and distributed generation. It is known that the communications infrastructure is an essential part for a successful implementation of SG architecture and the choice of a communication system is very particular due to several weaknesses in communication technologies...
Digital multiplexers 12 (DMX 512) is a standard for digital data transmission mainly to control stage lighting. Conventional DMX512 employs bus topology in a daisy chain network. The network consists of one master and one or more slave devices connected through wires. Although wired connection validates reliable data transfer, yet it increases network complexity, specifically, where wires can be prohibitively...
Industrial wireless networks are gradually being adopted in industry, especially due to the low installation costs and low maintenance provided by these systems. For the use in harsh environments, the communication system should provide reliable radio links and low power to allow battery powered devices. In this context, WirelessHART, ISA SP100.11a and WIA-PA protocols were developed to meet these...
The major determinants of success during internal cardioversion of atrial fibrillation (AF) are voltage, duration and intracardiac impedance (ICI). However, there is a paucity of published data regarding evidence of ICI dynamics during internal cardioversion of AF using very-low-tilt rectilinear (VLTR) waveforms with stepped energy protocols. In this study, patients with persistent AF were internally...
This document covers the adaptive ARQ proposal for WiMAX wireless broadband networks, including problem area identification (TCP over ARQ), analysis and solutions proposed.
Near-field communications (NFC) promises to create a whole new paradigm for the vast majority of cell phone users and is emerging as a near-term reality. What has been described as the confluence of RFID and cellular telephony will bring with it a wealth of new applications. The applications space, security mechanisms, and human interface are maturing; the service providers and payment companies are...
