Simulation is one of the main tools used to analyze new proposals in the Network-on-Chip (NoC) field. Among these simulators for analyzing and testing new ideas in NoC architectures, the Noxim simulator stands out, being used by many researchers due to the wireless support and open-source availability. An important issue at the simulation phase is the choice of workload, as it may affect testing the...
In recent years, wireless power transfer (WPT) technology has developed rapidly. In order to control power transmission and optimize efficiency, a large number of control methods have been proposed. Due to the unique inherent characteristics of the WPT system, the various control methods are faced to three challenges. First, transmission efficiency is significantly affected by the change in output...
We investigate the problem of computing Completely Independent Spanning Trees (CIST) under a practical approach. We aim to show that despite CISTs are very challenging to exhibit in some networks, they present a real interest in ad-hoc networks and can be computed to enhance the network robustness. We propose an original ILP formulation for CISTs and we show through simulation results on representative...
This paper describes a new implementation of the Elastic Multicast (EM) protocol including new design enhancements for improved dynamic operation. The paper also presents additional performance data collected from emulation-based mobile network experiments. EM is a low complexity extension to Simplified Multicast Forwarding (SMF) that adds group-specific dynamic pruning of the SMF-based multicast...
Field Communication Network is a complex communication network system with grid topology structure, so it is difficult to disable communication. The paper puts forward a strategy to search the topology structure using UAV. At first, the paper analyzes the characteristics of node center in Field Communication Network, combining with the direction-finding and localization ability of UAV, proving that...
A communication protocol for fog computing should be efficient, lightweight and customizable. In this work we focus in a communication protocol for fog nodes composed of wireless sensors, which are spatially distributed autonomous sensors monitoring physical or environmental conditions. Problems with data congestion and limited physical resources are common in these networks. For the optimization...
Misalignment during wireless charging of EVs can lead to low efficiencies (<85%) of power transfer which can lead to thermal issues and high leakage fields. This paper explores the most optimal solution towards a misalignment tolerant system. To that end, a DD-DDQ coil system with series-series compensation combined with an impedance matching control algorithm is explored. A multi-objective optimization...
Network lifetime is of great importance in WBANs that significantly influences the network performance and user experience. Among all the solutions to extend the network lifetime, relay mechanism plays a crucial role. However, previous works only concentrate on energy efficiency of sensor nodes regardless of energy storage diversity among sensor nodes, which may severely limit the performance of enhancing...
In dense wireless deployments, such as Enterprise WLANs (EWLANs) and home WLANs, interference may occur because of neighbouring WLANs sharing the same unlicensed spectrum. Mechanisms to centrally manage WLAN deployments cannot effectively mitigate the interference caused by hidden terminals (HTs) in WLANs that belong to different organisations. Furthermore, the impact of interference is amplified...
Energy consumption has become a key issue for running large-scale data center networks (DCN) nowadays. Previous studies mainly focus on energy saving through reducing the number of active servers or network switches with traffic consolidation. However, since this mechanism benefits from the routing flexibility, both the gained energy savings and flow performance are limited by the conventional static...
The control packets in the Data Center Networks (DCNs) have to contest with the data packets although they are usually much shorter in size and much more important in network management. Moreover, the uneven distribution of the packets may create potential hotspots in the DCN which could degrade network performance drastically. To bridge these gaps, a few proposals have been put forward to construct...
Introducing compressive sensing theory to solve multiple targets localization problem is a promising method by only considering received signal's power. In previous researches, the targets are assumed to be positioned into an regular mesh grid and restoration model according to compressive underdetermined equation is built to recover the positions of unknown targets. However, it is inconvenient to...
This paper proposes a novel, iterative, distributed Medium Access Control (MAC) for Multi-Transmit-Receive (MTR) Wireless Mesh Networks (WMNs). The MAC called PCP-TDMA aims to construct the shortest possible schedule that allows nodes to transmit to or receive from all their neighbors simultaneously over the same frequency. Compared to the state-of-the-art, namely a centralized algorithm called ALGO-2,...
Mobile backhauling, small cells and MmWave are key supportive technologies for 5G revolution. Mobile backhauling is the key enabler and also a showstopper for 5G small cells deployments. Scalability and reliability with high data rate and larger bandwidth are important factors to choose the small cell backhauling topology. In this paper, We consider the star and mesh topologies for the MmWave wireless...
The explosion of traffic demands within data centers accentuates the conventional infrastructures ossification. Unfortunately, the traditional tree based architectures struggle to resist and suffer from congestion and wiring complexity which deeply deteriorate the network performance. In aim to address the QoS degradation, we put forward a Hybrid Data Center Network (HDCN) architecture based on CISCO's...
We investigate the potential gains of Physical-Layer Network Coding (PLNC) in multi-hop wireless networks. Physical-Layer Network Coding was first introduced as a solution to increase the throughput of a two-way relay channel communication. Unlike most wireless communications techniques which try to avoid collisions, PLNC allows two simultaneous transmissions to a common receiver. Such transmitted...
In this poster, we consider software-defined wireless sensor networks (SDWSNs) and present a lightweight flow management to reconfigure flow entries in flow-table when link fault occurs in the data plane of SDWSNs.
Wireless sensor networks have found numerous applications in realistic environments. Typically, such networks are desirable to operate in several years without human maintenance. Yet main radio components on the conventional wireless sensors quickly consume most of the limited energy in the sensors, and thus considerably constrain the sensor lifetime. Recently, many low-power wake-up radios are designed...
Effect of resistive feedback on performance parameters of Common-Source (CS) low noise amplifier (LNA) is studied in this paper. For this purpose, an ultra low power, low noise figure (NF), high power gain (S21) low noise amplifier (LNA) for narrowband (NB) wireless applications is proposed in this paper. The LNA is designed for 2.4 GHz narrowband (NB) using 90nm CMOS process. It has a 3-dB bandwidth...
A promising approach for dealing with the increasing demand of data traffic is the use of device-to-device (D2D) technologies, in particular when the destination can be reached directly, or though few retransmissions by peer devices. Thus, the cellular network can offload local traffic that is transmitted by an ad hoc network, e.g., a mobile ad hoc network (MANET), or a vehicular ad hoc network (VANET)...
