In this work, we consider the downlink transmission of massive multiple input multiple output (MIMO) system subject to per-user power control. The outage probability is derived by applying inverse Laplace transform on moment generating function of inter-user interference. The method is applicable for Rayleight flat-fading channel with presence of pathloss. The simulation results validates the theoretical derivation.

In this study, we consider multiuser multi-input single-output (MISO) beamforming design in underlay cognitive radio networks in the presence of a primary user (PU) and eavesdropper (Eve). We propose a multi-objective optimization problem (MOOP) for balancing two conflicting design objectives: maximizing the total intended power received at secondary receivers and minimizing the interference power at the PU, while satisfying the secrecy rate and PU interference threshold constraints. The MOOP was solved by a weighted sum method and semidefinite programming relaxation (SDR), and the rank-one optimal solutions were drawn with explanations. The upper and lower bounds were found by solving the single-objective and zero-forcing beamforming problems. The simulation results demonstrated a trade-off between the objectives in the Pareto optimal set, no improvement of performance with artificial noise, and better results with increasing number of transmission antennas.

Several routing mechanisms for the Internet of Things (IoT) applications has been proposed by research community. RPL (IPv6 Routing Protocol for Low-Power and Lossy Networks), an IP-based distributed routing paradigm is considered as one standard developed by IETF. More recently, SDN-WISE protocol with centralized routing solution based on Software Defined Networking (SDN), is introduced. SDN-WISE is a stateful Wireless Sensor Networks (WSNs) paradigm that minimize the complexity of WSNs by reducing the number of messages exchanged. In SDN-WISE, routing polices are defined by a controller which is a software that can be anywhere in the network. In this paper, we develop a new mechanism for SDN-WISE, called Trickle timer, in order to optimize the network performance. Trickle timer allows sensor nodes in a wireless network to exchange few packets per hour when network’s state remains stable. Results show that SDN-WISE protocol with Trickle timer consumes very few energy, compared to the original SDN-WISE protocol, and has better performance in term of radio duty cycle, compared to RPL.
针对物联网(IoT)应用，研究人员提出了几种路由机制。RPL (IPv6 Routing Protocol for Low-Power and Lossy Networks)是一种基于ip的分布式路由模式，是IETF开发的一个标准。最近，提出了基于软件定义网络(SDN)的SDN- wise协议的集中路由解决方案。SDN-WISE是一种有状态无线传感器网络(WSNs)范例，通过减少交换的消息数量来最大限度地降低WSNs的复杂性。在SDN-WISE中，路由策略由控制器定义，控制器是一个可以在网络中任何位置的软件。在本文中，我们开发了一种新的SDN-WISE机制，称为涓流定时器，以优化网络性能。涓滴计时器允许无线网络中的传感器节点在网络状态保持稳定时每小时交换少量数据包。结果表明，与原始SDN-WISE协议相比，带有涓流定时器的SDN-WISE协议消耗的能量非常少，并且在无线电占空比方面具有比RPL更好的性能。

This paper presents the results on developing of a LC passive sensor utilizing capacitively coupled contactless detection structure for detection of defect inside a flow in miniaturized fluidic channel. The sensor operates based on the change in capacitance of the coupled capacitor when having a defect in the fluidic flow which results in the change of the resonance frequency of LC passive sensor. By monitoring the change of resonance frequency of the LC sensor, the presence of defect, i.e., an air bubble, in the fluidic flow can be detected. The distance between antennas has also been manipulated for finding the optimal configuration of the sensor. The dependent of resonance frequency change on the size of air bubble, as well as the location of air bubble has been investigated and analyzed. Experimental results show that the resonance frequency shifts up to 1.5 MHz correspond to the presence of an air bubble with volume of 196 nL in the flow.

This paper presents a public key based chaotic cryptosystem for image encryption operating in the integer field. The system is based on the discrete Cat-Hadamard map to encrypt bitmap images based on bit plane decomposing processes. The Chebyshev polynomials are used to determine the parameters of the Cat-Hadamard map. We show that the scheme offers very good resistance against exhaustive attacks, statistical attacks, and differential attacks. In addition, the computational cost of the scheme is limited, leading to a valid candidate for lightweight cryptography.

Today’s IP networks are complex and hard to manage. This is mainly due to vertical integration of control plane and data plane inside the network devices in traditional IP networks. Software Defined Networking (SDN) is a new networking paradigm that is promoted to resolve traditional networking issues. In SDN-enabled networks, a central controller dictates the behaviour of forwarding devices aiming to satisfy the requirements of network applications such as Quality of Service (QoS) related network applications e.g. packet loss rate, latency and throughput. The central controller accomplishes that by translating high-level policies into low-level commands and installing them on forwarding devices. This can be a very prolonged and time consuming process particularly, when the central controller aims to satisfy the requirements of multiple network applications at the same time. This paper provides a mathematical analysis on the response time offered by existing SDN approach followed by proposing an approach to decrease the response time.

This paper presents a Fabry–Perot antenna (FPA) with low-cost, broadband, high-gain, and high radiation efficiency. Its feed is a patch antenna, which is covered by a partially reflective surface (PRS) of 8 × 8 square aperture array. For the low realization cost, the antenna feed and the PRS are printed on thin low-cost FR4 substrates. In order to mitigate the FR4 material loss, a technique of air-substrate is applied into the antenna feed. This paper focuses not only a gain enhancement, but also a bandwidth improvement of the proposed antenna as compared to the conventional patch antenna. The final design of 125 mm × 125 mm × 23.5 mm (about 2.4λ0 × 2.4λ0 × 0.45λ0 at 5.8 GHz) achieves a |S11| < −10 dB bandwidth of 15.2% (5.31–6.19 GHz), the peak gain of 14.03 dBi, and a radiation efficiency of >95%. The proposed FPA produces a 150% increase in impedance matching bandwidth and a ~5.46-dB increase in the broadside gain relative to the conventional patch antenna.

Virtual machine (VM) migration is a technology dealing with the process of relocating a VM from one host to another. The relocation of VMs is usually assumed to be done in a single-step procedure, which however leads to a restriction on the degree of freedom. We therefore aim to consider a situation in which multi-step VM migrations are allowed. In this paper, by applying the concept of time-expanded networks [1], a novel optimisation model for virtual network function migration in multiple steps is introduced. Our model is based on the problem of virtual network embedding (VNE), which pertains to the mapping of virtual networks onto a capacitated substrate network and tackles the transition from one mapping to another in multiple passes. This publication is an extension of our previous work [2], which introduced the concept of soft bottlenecks and assumed deadline-restricted VM migrations. The work presented in this paper removes this restriction by allowing the migration time to vary in compliance with a variable VM image transfer rate, making the transition even more flexible. The obtained performance evaluation results underline the advantages of our multi-step VM migration model compared to any conventional single-step VM migration approaches.

This paper presents a design of phased array antenna using a full 360° and programmable continuous phase shifter based on angle of arrival techniques of indoor localization. This antenna system allows to electrically steer main beam direction smoothly, so the number of beams is independent of the number of antenna elements as previous research, and resolution for indoor localization system is improved. Antenna elements are fed through parallel feed network including Wilkinson power dividers and full 360°, continuous phase shifters. Radiation patterns, experimented from −45° to 45° in an anechoic chamber, show that the main beam direction is quite close to the desired direction in simulation, and the side lobe level is less than main beam about 10dB.
