The existence of rogue access points (RAP) poses a huge security threat to the wireless network environment. Therefore, it is of great significance to realize accurate positioning of RAP with low cost. At present, the main indoor positioning methods based on RSS (Received Signal Strength) are distance-based and fingerprint-based methods. The former is easy to implement but must ensure that the transmit power of the AP to be measured is known, while the latter often requires tedious deployment work. The problem of unknown transmit power brings great challenges for RAP positioning. In this paper, we propose a RSS-based heuristic algorithm for locating RAP. Firstly, the initial location of RAP is obtained by distance-based localization method, and then a simplified fingerprint-based method is adopted to improve the location precision. Our algorithm also gives the robust estimation interval of the localization effect on transmit power. Experimental results acquired in an office environment show that our proposed algorithm can locate RAP robustly and accurately without knowing the transmit power.

A four-stage wideband Variable Gain Amplifier (VGA) with linear-in-dB gain control characteristic is presented and designed in 0.18μm CMOS Technology. The modified Cherry-Hooper amplifier is employed for wide bandwidth and large gain tuning range. The input AC-coupling and the dual feedback DC-offset canceller are combined to suppress the undesired DC offsets. The pseudo-exponential function circuit is added to transform the linear-in-magnitude VGA into the linear-in-dB one. Simulation results show the presented VGA achieves 3-dB bandwidth of 1GHz, linear-in-dB gain tuning range of 56.7dB from -6.7dB to 50dB, and IP1-dB ranging from -60dB to -17dB. Besides, it consumes 7.7mW from a single supply voltage of 1.8V and occupies a silicon area of 100μm × 134μm.

The unique properties of single layer materials different from their bulk form make them suitable for nanoscale applications. This work presents study of p-i-n based Silicene Nanoribbon (SiNR) Tunnel Field Effect Transistor using NEGF formalism. The Device characteristics, ION/IOFF ratio have been studied by varying high-k dielectric, source and drain doping in SiNR TFET. The obtained ION/IOFF ratios for different gate dielectrics materials are compared with the reported data in literatures and it is observed that the ON current can be increased by using high-k dielectric but for the materials whose dielectric constant exceeds HfO2, OFF current will also increase. So, it can be inferred that deploying gate material of very high dielectric constant will not be of much benefit rather it will reduce ION/IOFF ratio, which is one of the key FOM in Digital VLSI circuits. HfO2 can be potential high-k material to be used as gate oxides because of its highest ION/IOFF ratio among all dielectric materials used for constant drain and source doping. OFF current is not much influenced by source doping however ON current increases due to wide tunneling window set up by gate potential for low source doping. OFF current and ambipolar conduction is increased by increasing drain doping concentration of SiNR TFET.

In this paper, a new mode-dependent average dwell time (MDADT) stability result of discrete-time switched systems with all subsystems unstable is investigated. Combined with MDADT analysis method, we classified subsystems into two categories: switching stable subsystems and switching unstable subsystems. State divergence caused by switching unstable subsystems could be compensated by activating switching stable subsystems for a sufficiently long time. Based on the above considerations, a new globally exponentially stability result was proposed for switched systems with all subsystems unstable. In addition, the new result is a generalization of the previous method, which is more suitable for the case of more unstable subsystems. Some numerical examples are given to illustrate the advantages of our established results.

Cloud computing with live migration technique is considered as one of the most promising ways to cope with power consumption and performance management of a data center. Most prior works on performance and power management of the whole server farm are achieved in a separate way. To address this issue, in this paper we propose an efficient method for the whole server farm, which aims to dynamically consolidate virtual machines in a coordinated way that optimizes the energy and performance trade-off. Firstly, we focus on the virtual machine (VM) selection step. Then we consider the VM selection task as a Dynamic Decision-Making (DDM) problem and construct a coordinated cost function with power and performance. In this study, the Q-Learning strategy of Reinforcement Learning (RL) is adopted to solve this DDM problem. The proposed algorithm is simulated in CloudSim toolkit using real-world workload traces. Finally, experimental results indicate that our approach outperforms other algorithms in terms of energy consumption, the number of VM migrations, average SLA violation and the number of host shutdowns.

Recent years, the popularity of wind power and the widely use of diversified loads have increased the uncertainty of power systems in both supply and demand sides. This paper develops a multi-time scale unit commitment optimization model under wind power and future load uncertainties. First, dayahead wind power and electric load forecast is obtained by long short-term memory network, based on which the on/off status and first-period output of units are determined. Then rolling economic dispatch is applied when real time data is collected from the system. To solve the above unit commitment and economic dispatch model, an improved particle swarm optimization algorithm is proposed. Finally, several experiment were performed to demonstrate the effectiveness of this research.

This paper presents a novel trisection wideband bandpass filter which is centered at 3.6 GHz with 50% fractional band width. The design process of this filter is based on frequency dependent coupling matrix. The frequency dependent coupling is introduced to the filter by separate electromagnetic coupling paths. Two transmission zeros are achieved near the passband. Another transmission zero is generated by harmonic effect. These transmission zeros together improve the selectivity of the filter. The filter was manufactured and measured. Measurements are in good agreement with the simulations.

In wireless communications research and application, Orthogonal Frequency Division Multiplexing (OFDM) has been established as a key PHY layer enabling technology (e.g., in both 4G and 5G cellular network standards). However, the Peak-to-Average-Ratio (PAPR) problem can lower system performance and has been under intense research in recent years. The trade-off between high PAPR reduction factor and high signal redundancy and/or computational complexity has not been sufficiently addressed by many works on this problem, and some approaches with state-of-the-art PAPR reduction performance suffer from high bit redundancy or have a higher complexity. So a method based on selected mapping orthogonal frequency division multiplexing modulation (SLM-OFDM) that generates (N2/4) symbol candidates using N inverse Fast Fourier Transform (FFT) is presented which is called GreenOFDM. In this paper, we propose an improved method based on GreenOFDM, We add a weighting factor α when generating the symbol candidates, and then select the symbol of the minimum PAPR for transmission. Computer simulation shows that this method is better than the original GreenOFDM When we choose the right weighting factor α. This not only gets lower signal redundancy, but also has lower complexity and simulation results show that the signal PAPR is significantly reduced.
