international symposium on information processing in sensor networks (IPSN)

作者： Minh-Long Pham Tor A. Ramstad Ilangko Balasingham Norwegian University of Science and Technology Trondheim Norway Interventional Center Rikshospitalet Medical Center Oslo Norway

Image transmission in biomedical wireless sensor networks often requires low complexity, low power consumption with soft real-time constraint. However, the full separation of source coding and channel coding usually comes with large delay and/or complexity. To address these requirements, we propose a new direct mapping of source sample to channel sample that utilizes large bandwidth of ultra wideband (UWB). Our system combines a 5/3 integer lifting scheme wavelet transform followed by a pulse position modulation (PPM). The system's major advantages are low complexity, low power consumption, low processing delay and robustness to error at sensor node. Evaluation on an image transmission system over additive white Gaussian noise (AWGN) channel shows that our proposed system can achieve lossless or near lossless image with significant energy saving and very low delay.

international symposium on information processing in sensor networks (IPSN)

Distributed simulation techniques are commonly used to improve the speed and scalability of wireless sensor network simulators. However, accurate simulations of dynamic interactions of sensor network applications incur large synchronization overheads and severely limit the performance of existing distributed simulators. In this paper, we present two novel techniques that significantly reduce such overheads by minimizing the number of sensor node synchronizations during simulations. These techniques work by exploiting radio and MAC specific characteristics without reducing simulation accuracy. In addition, we present a new probing mechanism that makes it possible to exploit any potential application specific characteristics for synchronization reductions. We implement and evaluate these techniques in a cycle accurate distributed simulation framework that we developed based on Avrora. In our experiments, the radio-level technique achieves a speedup of 2 to 3 times in simulating 1-hop networks with 32 to 256 nodes. With default backoffs, the MAC-level technique achieves a speedup of 1.1 to 1.3 times in the best case scenarios of simulating 32 and 64 nodes. In our multi-hop flooding tests, together they achieve a speedup of 1.5 to 1.8 times in simulating networks with 36 to 144 nodes. The experiments also demonstrate that the speedups can be significantly larger as the techniques scale with the number of processors and radio-off/MAC-backoff time.

international symposium on information processing in sensor networks (IPSN)

作者： Omprakash Gnawali Jongkeun Na Ramesh Govindan Computer Science Department University of Southern California USA

As sensor networks mature, there will be an increasing need for re-usable, dynamically taskable software systems that support multiple concurrent applications. In this paper, we consider the problem of energy management in such systems, taking Tenet as a case study. Our work considers energy management under three new constraints: dynamic multi-hop routing and tasking, multiple concurrent applications, and reliable end-toend data delivery. We present AEM, an energy management system that satisfies these constraints. AEM statically analyzes and infers the traffic profile for the application and accordingly tunes the duty-cycling protocol to provide the best trade-off in latency and data delivery performance. Furthermore, unlike other duty-cycling protocols with pre-computed or fixed transmission and reception time slots, AEM uses elastic schedules that allows it to adapt to dynamics while enabling bounded latency of event detection. Our experiments show that AEM achieves 1-3% duty-cycles, while allowing concurrent applications to transmit 100% of the sensor data in a multi-hop 40-node network testbed.

international symposium on information processing in sensor networks (IPSN)

作者： Lan S. Bai Robert P. Dick Peter A. Dinda University of Michigan USA Northwestern University USA

sensor network application experts such as biologists, geologists, and environmental engineers generally have little experience with, and little patience for, general-purpose and often low-level sensor network programming languages. We believe sensor network languages should be designed for application experts, who may not be expert programmers. To further that goal, we propose the concepts of sensor network application archetypes, archetype-specific languages, and archetype templates. Our work makes the following contributions. (1) We have examined a wide range of wireless sensor networks to develop a taxonomy of seven archetypes. This taxonomy permits the design of compact languages that are appropriate for novice programmers. (2) We developed a language (named WASP) and its associated compiler for a commonly encountered archetype. (3) We conducted user studies to evaluate the suitability of WASP and several alternatives for novice programmers. To the best of our knowledge, this 56-hour 28-user study is the first to evaluate a broad range of sensor network languages (TinyScript, Tiny-SQL, SwissQM, and TinyTemplate). On average, users of other languages successfully implemented their assigned applications 30.6% of the time. Among the successful completions, the average development time was 21.7 minutes. Users of WASP had an average success rate of 80.6%, and an average development time of 12.1 minutes (an improvement of 44.4%).

IEEE symposium (IUS) Ultrasonics

作者： N. Y. Kozlovski D. C. Malocha School of Electrical Engineering and Computer Science University of Central Florida Orlando FL USA

Previous work has been presented on passive wireless SAW sensors using the orthogonal frequency coding (OFC) technique. Wireless operation of such sensors has been demonstrated using a network analyzer and only one sensor at a time. A technique to allow multiple sensors to operate at the same time has been developed and demonstrated using network analyzer measurements that were added together to simulate simultaneous operation within the system. NASA is sponsoring research and development of SAW wireless, passive sensors that are environmentally robust and operate in a multisensor environment. This paper will present a first fully functioning 915 MHz interrogation system for passive wireless OFC SAW temperature sensors. The paper will present the interrogator hardware for the SAW sensors and the analytical model and how it is used to extract the temperature data from each particular sensor. Spread spectrum techniques are demonstrated that allow operation below the noise level by using processing gain techniques in a correlator synchronous receiver. The system presented has four sensors built on YZ LiNbO 3 around 915 MHz. Featured sensors consisted of wide band, eighth wavelength electrode transducer operating at the 3rd harmonic and two symmetrically placed reflector banks on either side of the transducer operating at the 2nd harmonic. A 35.192 MHz clock is used to control the digital control of the interrogator circuit and to produce the 915 MHz interrogating signal. Temperature is extracted from the sensor using an adaptive filter correlator technique. A four-sensor passive wireless system has been demonstrated. sensors were subjected to various temperatures ranging from -40?C to 65?C. sensors were randomly positioned within a 5cm radius of each other. The four designed sensors demonstrated excellent anti-collision properties crucial for multi-sensor operation. The system has demonstrated good code anti-collision properties. It is shown that the passive wireless

IEEE international symposium on Dependable, Autonomic and Secure Computing (DASC)

作者： Chih-Chun Lin She-Shang Xue Leehter Yao Intelligent Control Laboratory Department of Electrical Engineering National Taipei University of Technology Taipei Taiwan

The design and implementation of a three-dimensional (3D) location system to provide accurate location information is proposed in this paper. The location information is computed by two techniques. Both Trilateration technique and the Time Difference of Arrival (TDOA) are applied to three sets of collected distance measurements and to obtain accurate distance measurements between the Transmission processing Unit (TPU) and the Distance sensor (DSR) module. TPU works as the beacon transmitter of infrared (IR) and ultrasonic signals, while DSRs act as fixed reference points of the locating system and are generally attached to the ceiling and wall of the room. Each DSR is a receiver of IR and ultrasonic signals. Up to 250 DSRs are arranged and connected together on a single RS-485 bus called sensor Grid (SG). Located at the end of the RS-485 bus, the sensor processing Unit (SPU) collects and sends data produced by DSR to TPU using Zigbee modules in the construction of a Wireless sensor Network (WSN). Both Trilateration technique and Kalman filter are implemented to improve the accuracy of the location system. The 3D system is able to provide accurate locations for path tracking in robot navigation experiments conducted at a large indoor area.

3rd international symposium on Wireless Pervasive Computing

In this paper we propose a scheme for self-organizing sensor networks;the scheme allows a sensor network to adapt to topological changes, include new batches of sensors, and disregard the sensors that have depleted their power reserves, or have been compromised. The algorithm for self-organization allows the sensor network to carry out its mission, has built-in provisions for information assurance, and extends the lifetime of the network by reducing the power consumption;it minimizes the number of collisions experienced by a sensor when it transmits and maximizes the time a sensor is either idle or dedicated to monitoring and/or internal data processing.

One of the main issues with wireless sensor networks (WSNs) is communication efficiency to reduce power consumption. This is often achieved through data routing with aggregation. However, aggregation does not consider possible measurements correlation. This a priori information can be used for data fusion, in order to remove correlation of transmitted data, thus reducing amount of information to be transmitted. In this paper we explore different information processing strategy for state estimation of dynamic linear systems in the context of rooted wireless sensor networks. We propose three data fusion methods: standard measurement aggregation, measurement fusion, and fusion of partial state estimates. These strategies are specifically designed to include possible delayed or dropped packets. Finally, they are compared in term of power consumption efficiency, estimation accuracy, computational and memory complexity, showing tradeoffs between these metrics.

In modern vehicles an increasing number of control systems is based on measurements of signals describing vehicle dynamics. Correspondingly, a large number of sensors is required. To spare on weight and even more important on costs, car manufacturers require joint processing of sensors, i.e. the individual sensors related to certain control systems should become part of a sensor network. In the paper at hand the possibilities and shortcomings of such an approach are examined from a sensor monitoring and estimation perspective. Especially, redundant and model based failure detection are considered. The focus is on signals and sensors related to vehicle dynamics and the corresponding question of fall back strategies in case of sensor failure. Corresponding problems are addressed by a suitable sensor network architecture.

In today's net-centric warfare environment, effective management and use of the electromagnetic spectrum is critical. Increasing demands on wireless spectrum from radio traffic, unmanned aerial vehicle (UAV) communication, wireless networks, improvised explosive device (IED) jammers, and sensor networks result in sources competing for, and at times conflicting over, limited frequency spectrum. From an intelligence perspective, having a clear understanding of the RF environment, both friendly and foe, is an important essential of battlefield management. This paper presents the sensor Collection and Analysis of Radio Frequencies (SCARF) system with a focus on the information processing requirements of the sensors and various system components. The overall architecture, sensor processing and fusion challenges, visualization algorithms, and current implementation status are discussed.
