World Congress on Nature & Biologically Inspired Computing (NaBIC)

作者： Om Prakash Acharya Amalendu Patnaik Balamati Choudhury Department of Electronics and Computer Engineering Indian Institute of Technology Roorkee Uttarakhand India Computational Electromagnetics Laboratory AeroSpace Electronics and System Division National AeroSpace Laboratories (NAL-CSIR) Bangalore India

In this paper an approach using the Particle Swarm Optimization(PSO) is proposed which allows to locate the defective elements in an antenna array. A cost function has been proposed using the array factor of the defected array that can lead to the location of the defective antenna elements in the array. Complete fault as well as partial fault elements are considered in the formulation. Although in this paper the formulation has been developed for linear array, it can easily be extended to case of a planar array.

IEEE International Workshop on Intelligent Data Acquisition and Advanced Computing systems: Technology and Applications

作者： L. Skrzypczak D. Grimaldi R. Rak Department of Electronics Computer and System Sciences University of Calabria Cosenza Italy Institute of the Theory of Electrical Engineering Information and Measurement Systems Electrical Engineering Faculty Warsaw University of Technology Warsaw Poland

In order to make modern measurement systems more flexible, faster and easier to configure and use, the implementation of wireless technology is needed into the Distributed Measurement system (DMS). There is a number of wireless standards available on the market, each one with unique characteristics. The paper is an attempt at categorizing different wireless standards to meet specific requirements of the DMSs. Innovative system architectures making use of modern microcontrollers and multiple wireless transmission standards were taken into account. In order to analyze the characteristics different wireless transmission standard (such as ZigBee and SimpliciTI.) in the operating condition available into the wireless DMS, experimental tests were devoted. The information obtained from theses experimental tests are used to develop a new design approach of the wireless connection into the DMS to integrate different standards and to achieve best transmission properties.

IEEE International Symposium on Broadband Multimedia systems and Broadcasting (BMSB)

作者： Sung Ik Park Homin Eum So Ra Park Geon Kim Yong Tae Lee Heung Mook Kim Wangrok Oh Broadcasting System Research Department Electronics and Telecommunications Research Institute Daejeon South Korea Div. of Electrical and Computer Engineering Chungnam National University Daejeon South Korea

This paper proposes a novel equalization on-channel repeater (OCR) with feedback interference canceller (FIC) to relay the terrestrial digital multimedia broadcasting (T-DMB) signals in single frequency networks (SFN). The proposed OCR does not have only high output power by cancelling feedback signals caused by insufficient antenna isolation through the FIC, but also shows better quality of output signals than the conventional OCR by removing multipath signals existing between the main transmitter and the OCR through an equalizer. In addition, computer simulations and laboratory test results are provided to figure out performance of the proposed OCR.

International Conference on Intelligent Transportation

作者： Sunisa Promnoi Poj Tangamchit Wasan Pattara-Atikom Department of Control System and Instrumentation Engineering King Mongkut's University of Technology Thonburi Bangkok Thailand National Electronics and Computer Technology Center Klong Luang Pathum Thani Thailand

This paper presents a road traffic estimation method using a GSM mobile phone as a probe. The technique relies on localization by signal strength matching. Our emphasis is on the unusual-large size of the database. We built a module that automatically collects location-signal with one second refresh rate and carried it along a test route to collect database. To handle big database, we additionally present a noise reduction algorithm, which eliminates bad data and compacts the database. For the localization algorithm, the fast nearest neighbor strategy is applied in the database matching to reduce computation time. The position estimations which formerly implemented noise reduction are compared with the ordinary results. Furthermore, we compared the computation time of the fast nearest neighbor algorithm to the normal method. The results show that the mobile phone positioning based on signal strength pattern matching can locate its location down to 63 meter accuracy.

International Conference on computer Communications and Networks (ICCCN)

作者： L. B. Lim L. Guan A. Grigg I. W. Phillips X. G. Wang I. U. Awan Department of Computer Science Loughborough University UK System Engineering Innovation Centre (SEIC) Loughborough University UK School of Computing Communication and Electronics University of Plymouth UK Department of Computing University of Bradford UK

This paper presents a comprehensive analytical approach to maintain queuing delay in a router at a required level through closed-loop feedback control under aggregated traffic flows from various traffic classes. The approach is able to bound average queuing delay but still achieve a high system utilization by regulating traffic arrival rate implicitly through a movable queuing threshold. The queuing threshold is adjusted dynamically through feedback of average queuing delay measurement. Consequently, packets are dropped dynamically with respect to the changes of queuing threshold and the packets loss event served as an implicit congestion indicator. Three major contributions are given in this paper: (1) a discrete time queuing model is developed to derive the mapping table of average queuing delay and queuing threshold; (2) a traffic model that models LRD aggregated Internet traffic through superposing of N MMBP-2 arrival processes; (3) a closed-loop feedback control to control queuing delay at its target level based on expected system utilization. Matlab is used to perform queuing analysis and simulation. Statistical evaluation is performed to show the efficiency and accuracy of the analytical and simulation results.

The successful operation of CDMA systems depend on the use of power control. This is needed to address the "near far" effect and to mitigate the effects of fading. Other factors also impact on the achievable performance of the power control loop including the fact that only the sign of the power increments are transmitted. The paper presents new methods and results to improve control with respect to the latter strongly non-linear effect. An adaptive control architecture, having three degrees of freedom, is therefore proposed for inner loop power control. The three degrees of freedom are used to address errors resulting from (i) channel and interference variations, (ii) quantization of the power increments and (iii) saturation of the power increments. Simulations show that the proposed controller outperforms other related schemes. A major reason for this is the ability of the three degree of freedom controller to reduce the variation of the control signal to be quantized.

Fadlullah Dario Bottazzi Nidal Nasser Yunfeng Chen NEC Europe Limited Germany Graduate School of Information Sciences University of Tohoku Japan Department of Electronics Computer Science and System Engineering University of Bologna Italy Department of Computing and Information Science University of Guelph Canada

Recent advances in wireless technology, sensors and portable devices offer interesting opportunities to enable ubiquitous assistance to individuals in need of prompt help. Providing healthcare services to mobile users, such as, patients, elders, or potential drug abusers, is a rather challenging task. Novel middleware-level supports are required to integrate sensor infrastructures capable of detecting changes in the monitored subjects' health conditions and of alerting medical personnel, and the victim's relatives and friends in case of emergency situations. Along this line, the paper envisions a context-aware middleware-level solution dubbed Pervasive Environment for Affective Healthcare (PEACH). PEACH integrates together various sensors in a Wireless Body Area Network (WBAN) to detect alterations of monitored subjects' affective and physical conditions, aggregate the sensed information, and also detect potentially dangerous situations for the monitored subject. Finally, PEACH aims at providing outdoor assistance to the victim/patient by quickly promoting the formation of ad hoc rescue groups comprising nearby volunteers. Through encouraging results obtained from both simulations and a practical drug-rehabilitation application testbed, the effectiveness of the envisioned PEACH framework is verified.

Load Balancing Routing Algorithm for Ad Hoc Networks

Load Balancing Routing Algorithm for Ad Hoc Networks

International Conference on Mobile Ad-hoc and Sensor Networks, MSN

作者： Wenbin Jiang Zhaojing Li Chunqiang Zeng Hai Jin Services Computing Technology and System Laboratory School of Computer Science and Technology Huazhong University of Science and Technology Wuhan China Department of Electronics and Information Engineering Huazhong University of Science and Technology Wuhan China

In ad hoc networks, when the load is heavy, the performance of on-demand routing protocols, such as DSR protocol, will suffer large degradation. For instance, the absence of balanced distribution of network flow among nodes in the whole network is highly prone to producing heavy-load key nodes. This results in fast energy consumption of these key nodes, and finally decreasing the survival time of the network caused by their premature failures. To address this problem, a novel algorithm called cross-layer based load balancing algorithm for DSR (CLB-DSR) is proposed. In CLB-DSR, the cross-layer strategy is adopted to exchange the information between data link layer and network layer. Simulation results show that the improved routing protocol using CLB-DSR can effectively balance network load, improve the network throughput and reduce the end-to-end delay, the rate of data dropped.

In this paper, a comprehensive cross correlation-based fault diagnostic method is proposed for real time DSP implementation. It covers both fault monitoring and decision making stages. In practice, a motor driven by an adjustable speed drive is run at various operating points where the frequency, amplitude and phase of the fault signatures varies with time. These dynamic changes are considered as one of the common factor that yields erroneous fault tracking and unstable fault detection. In this paper, the proposed algorithms deals with the operating point dependent ambiguities and threshold issues. It is theoretically and experimentally verified that the motor fault can continuously be tracked when the operating point changes within a limited range.
