Long Range (LoRa) is a proprietary modulation technique that uses Chirp Spread Spectrum (CSS) modulation for low power and wide area communications. Despite the advantages of LoRa technology, the reconfiguration of transmission parameters such as Spreading Factor (SF) and Transmission Power (Ptx), remains limited to maximize the uplink traffic. In...

This book addresses the key problems that computational intelligence aims to solve, including (i) the involved computational process might be too complex for mathematical reasoning; (ii) it might contain some uncertainties during the process, or (iii) by nature, the computational process is a randomly determined one (heuristic). The contributors ma...

Performance and communication security in the Internet of Things (IoT) area draw a major concern for both academic and industrial communities. Indeed, an emerging number of IoT protocols are getting involved in the protocol stack, implying that the need for new security measures is also increasing. The Media Access Control (MAC) protocol Time Slot...

Vehicular ad-hoc networks play an important role in providing safety on the road. Vehicles generate and exchange emergency and control messages to avoid dangerous situations. According to IEEE 1609.4 standard, all these messages share the same control channel interval even if the emergency messages are with a highest priority. Besides that, network...

Software Defined Radio (SDR) platforms are useful tools to design new wireless technologies or to improve specifications of existing ones. The IEEE 802.11p is the de-facto standard for Wireless Vehicular Ad-hoc NETworks (VANETs). It has been implemented on GNU Radio SDR [1], which experiences frames decoding/encoding latency. In this paper an FPGA...

Channel capacity and software definition of radio functions are important issues for Vehicular Ad-hoc NETworks (VANETs). In our paper, we propose to integrate a 5G radio access technology to software defined PHY layer of IEEE 802.11p for frequency reuse. We superpose two signals with Non-orthogonal Multiple Access (NOMA), and we extract them throug...

Universal Software Radio Peripheral (USRP) and GNU Radio are well known Software Defined Radio (SDR) tools. The USRPs designed by Ettus Research are used without a deep knowledge of their performances. In this paper, we report our output power measurements using a USRP B210 driven by a GNU Radio program. Our results show that the obtained output po...

In this paper we report Radio Frequency (RF) measurements performed on a GNU Radio/Universal Software Radio Peripheral (USRP) testbed. The USRP hardware is connected to SBX daughter board, both designed by Ettus Research. We can confirm the bandwidth stated by the designer, nonetheless the output power was found to be constantly decreasing with inc...

This poster reports Radio Frequency measurements performed with SBX daughter boards, USRP N210 and GNU Radio. We measured the output power across a frequency bandwidth and then we calculated the Total Harmonic Distortion (THD). We confirm the bandwidth stated by Ettus Research. However, the output power was found to be constantly decreasing with in...

Our paper deals with a Dynamic Spectrum Access (DSA) and its implementation on a Software Defined Radio (SDR) for IEEE 802.15.4e Networks. The network nodes select the carrier frequency after Energy-Detection based Spectrum Sensing (SS). To ensure frequency hoping between two nodes in IEEE 802.15.4e Network, we propose a synchronization algorithm....

In this paper, we propose an empirical model based on Radio Frequency (RF) measurements. The output power is measured sweeping a frequency band from 350 MHz to 4400 MHz of four SBX daughter boards [4]. These daughter boards are connected to a Universal Software Radio Peripheral (USRP) N210. For each carrier frequency, a narrow-band sinusoidal signa...

In this paper, we report a series of RF (Radio Frequency) measurements performed on a USRP and a GNU Radio Software Defined Radio (SDR). The RFX 900 and RFX 2400 Daughter Boards are connected to an USRP N210 platform and driven by the GNU Radio open source software. We focused on two main aspects: the output RF bandwidth and the power linearity ver...

This paper reports an implementation of the PHY specifications of the IEEE 802.15.4 standard for the frequency band 868 915 MHz on a Software Defined Radio (SDR) platform. This standard is defined for low power, low data rate and low cost wireless networks. These specifications are used by the Zigbee technology for various applications such as home...
