The RATS radio traffic collection system
The DARPA RATS Program focuses on the development of new technologies for identifying and processing speaker-tospeaker communications over degraded radio channels. In order to build a corpus to address this research question, we developed a system that takes a clean source signal and transmits it over eight different radio channels, where the variation from channel to channel results in a range...
متن کاملTraffic Analysis with Cognitive Radio Spectrum
Most of the existing DSA schemes are the unlicensed user, traffic in a licensed spectrum without compromising the transmissions of the licensed users, in which all the unlicensed users are typically treated equally. Dynamic spectrum access (DSA) is an important design aspect for the cognitive radio networks. Specifically, the unlicensed user traffic is divided into two priority classes (i.e., h...
متن کاملTraffic distribution in composite radio environments
This paper adopts the assumption that cellular, Broadband Fixed Wireless Access (BFWA) and DVB systems can be co-operating components of a compositeradio infrastructure. It is believed that through the composite radio concept operators will be enabled to offer very efficient, in terms of cost and Quality of Service (QoS), wireless access to broadband IP-based services. The exploitation of this ...
متن کامل868 MHz Traffic Detective: A Software-Based Tool for Radio Traffic Monitoring
Radio traffic monitoring is a crucial task whenever different and incompatible radio frequency (RF) communication standards simultaneously exist within a given environment. In this paper, we present a software-based tool for RF traffic monitoring and diagnosis within the European 868 MHz Short Range Device (SRD) band that is composed of commercially available low-cost receiver hardware and an a...
متن کاملTraffic Aware Channel Assignment For Multi Radio Wireless mesh Network
With the rapid development of Ad hoc networks and a wireless mesh networks (WLAN) will become the next generation of new broadband wireless network with characters of multi-hop, self-organizing, self-healing, high robustness and high bandwidth. Through in-depth study of the network performance, It is observed that there is a serious interference and network connectivity issues between Wireless ...
