Wireless sensor networks (WSNs) are based on monitoring or managing the sensing area by using the location information with sensor nodes. Most sensor nodes need hardware support or receive packets with location information to estimate their location, and this needs lots of time or costs, and may have a huge error. In this paper we present a localization mechanism in wireless sensor networks (MRN). We use a mobile reference node with GPS to move to the whole environment, and we use RSSI and trilateration to estimate unknown nodes' location. We can obtain more unknown nodes location by mobile reference node moving scheme, and will decreases the energy consumption and average location error.

Heterogeneous network (HetNet) deployment strategies have the potential to improve the energy efficiency of mobile access networks. One key aspect to consider in HetNets is the impact of the power consumption of the backhaul, i.e., the overall energy efficiency of a HetNet deployment is affected by the backhaul technology and architecture. This paper presents a preliminary assessment of the design challenges of a future green backhaul segment for a HetNet deployment. The study is based on the analysis of the medium term future outlook (i.e., between now and the year 2025) of the main technologies used in todays'* backhaul networks (i.e., fiber, microwave and copper). It can be concluded that, even if there arc no doubts that both microwave and fiber will be predominately used in the future, the possible migration paths leading to such fiber- and microwave-dominated scenarios might be different, depending on factors such as spectrum and license costs, time to deployment, availability of equipment, and required Quality of Service (QoS) levels.

Adaptive Fourier analysis has numerous applications in biomedical engineering, music signal processing, digital communications, power engineering etc. So far, a lot of adaptive algorithms and systems have been developed and applied. In this paper, a variable step-size LMS (VSS-LMS) algorithm is proposed for adaptive Fourier analysis of noisy sinusoidal signals. It significantly outperforms the conventional LMS and p-power algorithms in both stationary and nonstationary environments at the expense of very little increase in computational cost. Extensive simulations as well as application to real noise signals generated by large-scale factory rotating machines are conducted to confirm the improved performance and tracking capabilities of the proposed algorithm.

This paper studies the performance of the power-level-difference(PLD)-based two-channel noise reduction for dual-microphone headsets by using Monte Carlo simulation method. The analysis results indicate that both the accuracy of the noise power spectral density (NPSD) estimation and the smoothing factor have significant impacts on the amount of noise reduction. Based on these analysis results, a modified PLD-based two-channel noise reduction algorithm is proposed, where two schemes are introduced to improve the performance of the traditional PLD-based algorithm. In the first scheme, a non-stationary noise estimator is proposed to improve the tracking capability of the NPSD estimator. In the second scheme, an adaptive updating smoothing factor (AUSF) is used to reduce the variance of the spectral estimation and increase the amount of noise reduction. Experimental results with recorded data show better performance of the proposed algorithm.

In this paper, an efficient fast algorithm called Boundary-aided Extreme Value Detection (BEVD) is applied to predict the best direction mode, excluding the DC mode, for H.264/AVC fast intra-mode decision. The BEVD-based two-step edge detection can predict luma-4×4, luma-16×16, and chroma-8×8 modes effectively. Simulation results show that the proposed BEVD method reduces encoding time by 63 %, and requires a bit-rate increase of approximately 1.7 %, and a decrease in peak signal-to-noise ratio (PSNR) by approximately 0.06 dB in CIF sequences, compared with the H.264/AVC JM 14.2 software. The proposed BEVD processor includes the memory unit, the system controller, and the BEVD core module. With TSMC 0.18 μm CMOS process, the proposed BEVD processor requires 16.4 K gates and performs the maximum operational frequency up to 71 MHz, and can be applied to the real-time HD format video encoding.

In this paper, a novel method is proposed to design FIR filters. In our designs, the objective is to reduce the minimax approximation error of an FIR filter subject to peak error constraints imposed on group delays in passbands. Starting from an initial design, the proposed method employs an iterative procedure. In each iterative step, a nonlinear equation is solved to make group delay constraints satisfied. Simulation results demonstrate that the proposed method can achieve FIR filters which satisfy group delay constraints arbitrarily specified in passbands.

This paper proposes a comb filter with adaptive notch bandwidth. The comb filter is used to reduce a periodic noise from an observed signal. To extract the desired signal completely, we should appropriately design the notch bandwidth of the comb filter. Specifically, we should design the notch bandwidth to be equal to the fluctuation bandwidth. In this paper, to automatically reduce only the periodic noise with the frequency fluctuation, we propose the comb filter which achieves the adaptive notch bandwidth. Simulation results show the effectiveness of the proposed comb filter.

The theory of compressive sensing (CS) enables the reconstruction of a sparse signal from highly compressed data. However, in many applications, we are ultimately interested in information retrieval rather than signal reconstruction. In this paper, we study the problem of multi-objects classification in compressive sensing systems. Theoretical error bounds are derived based on the analysis of classical compressive classification. The optimal projection matrix design problem is studied and an algorithm is derived to solve the corresponding problem. Application in the identification of license plate numbers is considered and simulation results show that the projection measurement obtained using the proposed algorithm significantly improve the classification performance in terms of classification error rate.

Unstable link connectivity due to dynamic mobility nature of mobile phone users and error prone wireless link quality increases end-to-end delay for mobile phone based opportunistic network applications. This problem becomes more worse in the presence of large amount of data transmission, like multimedia data. This paper refers to Levy walk based multi-hop data forwarding protocol called Data Transmission Time and Human Walk Velocity (DTT-HWV) for Opportunistic Mobile Phone Sensor Networks (OMPSN). This paper, in particular evaluates the performance of proposed protocol in terms of end-to-end waiting time to receive data, which is an important QoS requirement for data transmission in opportunistic networks. The proposed protocol DTT-HWV reduces end-to-end waiting time to receive data compared to Random Progress (RP) data forwarding method in presence of low battery power and high path loss. Obtained results are helpful in designing and building of large scale data retrieval services for opportunistic networks involving humans in the communication network loop.

We present the use of an ultra-narrow spectrum-sliced incoherent light source for transmission of 10-Gb/s non-return-to-zero signals for wavelength-division-multiplexed passive optical networks. In this light source, a broadband amplified spontaneous emission noise is spectrum-sliced by an ultra-narrow filter and then fed to a gain-saturated semiconductor optical amplifier to suppress the excess intensity noise of the incoherent light. 10-Gb/s modulation is followed using a polarization-insensitive optical modulator. Thanks to the ultra-narrow linewidth of the source (~0.01 nm), not only is the 10-Gb/s incoherent signal successfully transmitted over 20-km standard single-mode fiber without any dispersion compensation, but also retains the noise suppression after passing through a 0.2-nm-bandwidth narrow optical filter. Two different line rates of 10.7 and 12.5 Gb/s are experimentally demonstrated, assuming 7% and 25% forward error correction, respectively. Also presented is the 10-Gb/s upstream transmission over a loopback configured network.
