conference on unmanned and unattended sensors and sensors networks

ISBN: (纸本)0819455644

Real-time and detailed information is critical to the success of ground combat forces. Current manned reconnaissance, surveillance, and target acquisition (RSTA) capabilities are not sufficient to cover battlefield intelligence gaps, provide Beyond-Line-of-Sight (BLOS) targeting, and the ambush avoidance information necessary for combat forces operating in hostile situations, complex terrain, and conducting military operations in urban terrain. This paper describes a current US Army program developing advanced networked unmanned/unaftended sensor systems to surveil these gaps and provide the Commander with real-time, pertinent information. Networked sensors for the Combat Forces plans to develop and demonstrate a new generation of low cost distributed unmanned sensor systems organic to the RSTA Element. Networked unmanned sensors will provide remote monitoring of gaps, will increase a unit's area of coverage, and will provide the command organic assets to complete his Battlefield Situational Awareness (BSA) picture for direct and indirect fire weapons, early warning, and threat avoidance. Current efforts include developing sensor packages for unmanned ground vehicles, small unmanned aerial vehicles, and unattended ground sensors using advanced sensor technologies. These sensors will be integrated with robust networked communications and Battle Command tools for mission planning, intelligence "reachback", and sensor data management. The network architecture design is based on a model that identifies a three-part modular design: 1) standardized sensor message protocols, 2) sensor Data Management, and 3) Service Oriented Architecture. This simple model provides maximum flexibility for data exchange, information management and distribution. Products include: sensor suites optimized for unmanned platforms, stationary and mobile versions of the sensor Data Management Center, Battle Command planning tools, networked communications, and sensor management software.

conference on unattended/unmanned Ground, Ocean and Air sensor Technologies and Applications VI

作者： Morgan, PF U.S. Special Operations Command (United States)

ISBN: (纸本)0819453404

unattended Ground sensor Systems (UGSS) are evolving from large (physical) scale sensing and processing to microelectronic systems capable of processing sensed information and imagery in near-real time on movement of vehicles and personnel. Equipment needed by Special Operations Forces (SOF) includes remote wireless sensor suites comprised of sensor arrays of 'Motes' (magnetic, acoustic, seismic and/or micro-impulse radar), Radio Frequency (RF) relays, remote sensor controllers, with supporting long haul exfiltration, methods to visualize and analyze the information returned, and finally, a command and control capability that allows the sensors to be remotely accessed for turn on and off. This presentation will discuss the technology requirements of UGSS for the Special Operations Community in the areas of special reconnaissance, environmental reconnaissance, coastal patrol, targeting, and threat assessment. Specific emphasis will be placed on, power technology, image compression, communications, micro-robotics, sensing devices and technology to include biological and chemical sensors. Self-forming sensor networks, high resolution still and motion cameras, laser systems, and data collection will also be addressed. In addition, this presentation will present a set of scenarios used in experimentation with unattended sensors.

conference on unmanned and unattended sensors and sensors networks

ISBN: (纸本)0819455644

Guarding safety and security within industrial, commercial and military areas is an important issue nowadays. A specific challenge lies in the design of portable surveillance systems that can be rapidly deployed, installed and easily operated. Conventional surveillance systems typically employ standalone sensors that transmit their data to a central control station for data-processing. One of the disadvantages of these kinds of systems is that they generate a lot of data that may induce processing or storage problems. Moreover, data from the sensors must be constantly observed and assessed by human operators. hi this paper, a surveillance concept based on distributed intelligence in wireless sensor networks is proposed. In this concept, surveillance is automatically performed by means of many small sensing devices including cameras. The requirements for such surveillance systems are investigated. Experiments with a demonstration system were conducted to verify some of the claims made throughout this paper.

Acoustic sensors have had a long history of use in military applications. Some of the factors favoring their use are: their ability to exploit loud and distinctive emissions of vehicles and weapons firings, their capability to detect and track targets in non line-of-sight conditions, and the ability to carry out their mission in a totally passive way (no emissions to give out their position). Acoustic-seismic sensors can also be implemented using low-power electronics. Acoustic-seismic sensors are now found in various surveillance sensors, generally known as unattended Ground sensors or UGS. The trend towards increasing computational capabilities, lower power consumption and better communications capacity have made these devices more useful and acceptable in a variety of military and peace-keeping operations. The promise of networked sensors has opened the possibility of large-scale sensor networks. However, we must be realistic about what can and cannot be achieved within the current technical horizon. The dream of "sensor dust": miniature devices, built and deployed at minimum cost, transmitting volumes of data is at present, just that, a dream that has to be tempered with the realities imposed by physics.

This paper examines some of the challenges facing the community in providing radio communications to enable information systems for military operations. We believe that much of the on-going/completed work is necessary, but not sufficient, to provide the military Network Centric Operations, which integrates military's network centric enterprise with network centric warfare. Additional issues need to be addressed to better support battle commanders as well as decider-sensor-effector linkages. We discuss a possible way ahead.

Digital modulation schemes have been thoroughly examined over the last decades in order to improve the performance over wireless channels in terms of capacity or BER vs SNR. sensor networks belong to a special category of wireless networks where energy awareness may be more important than any other aspect such us bandwidth efficiency or Quality of Service. Hence, the criteria in order to choose the appropriate modulation scheme are quite different from any other application. In this paper we examine the available modulation schemes taking into account energy constraints, and based on an existing model, we propose an adaptive modulation scheme as a means to achieve better performance in terms of energy consumption.

conference on unmanned and unattended sensors and sensors networks

Solar blind ultraviolet communication systems can provide short to medium range non line-of-sight and line-of-sight links which are covert and insensitive to meteorological conditions. Operation in the solar blind region provides zero background conditions and strong scattering interactions. Scattering provides the basis for transferring information when non line-of-sight conditions exist. Zero background conditions are a result of strong absorption of solar radiation in the upper atmosphere. These conditions make it possible to operate very sensitive wide field-of-view quantum noise limited photon counting receivers, and provide communication systems that perform very differently than free space optical systems that operate in other spectral regions. These systems may be compact and require very low primary power for operation. Non line-of-sight ultraviolet communication systems can provide reliable inter-nodal communications for unattended ground sensor networks. This type of system is particularly attractive when non line-of-sight conditions exist between nodes, covert operation is required, and insensitivity to positioning and ground proximity are desired. Light emitting diode technology being developed under the DARPA SUVOS program represents an enabling technology for these systems. Small, low power and low cost systems compatible with unattended ground sensor networks will be available as a result of this program. Data rates of hundreds of kbps with bit error rates (BER) of 10(-7) and inter-nodal ranges of hundreds of meters are consistent with phenomenology and technology. Line-of-sight ultraviolet communication systems also offer some unique characteristics for exfiltration of data from an unattended ground sensor network. The absence of background radiation makes it possible to operate with wide field-of-view receivers and large transmitter cone angles. This capability significantly reduces acquisition/pointing/tracking requirements that are traditionally

Modal Interference Fibre Optic sensor (MIFOS) for permanent monitoring of the network is presented. A mechanical disturbance of a fibre cable influences on intensity distribution at the end-face of a multimode fibre. Variations in interfering images are analysed by means of a digital processing unit that determines the alarm in case of unauthorised access along the whole length of the fibre. A contrast of an interference pattern and a procedure of fibre optic selection for the sensor are shown. A simple criterion that bases on changes of local maximums positions of the interference patterns is applied. A laboratory arrangement of the sensor and its experimental research are shown.

Quantum Magnetics has developed an autonomous battery-powered magnetic sensor node for distributed wireless sensor networks. The device digitizes the sensor output signals and transmits data over an RF link using a ZigBee 802.15.4 protocol. The prototype node incorporates Magneto-Resistive (MR) chips configured to measure all three components of the magnetic field, a logic device, analog-to-digital converters, a two-axis tilt sensor, a wireless transceiver, and a set of batteries, For use in outdoor environments, the sensor node is also GPS-ready. At present, the unit measures approximately 4 inches on a side, with about 40% of the volume occupied by the batteries. Using battery power, the node can operate for about 10 hours in a continuous mode and up to 40 hours with a 10% duty cycle. Efforts are underway to develop the next-generation magnetic node with significant reduction in size and part count.

Optimal topologies for wireless sensor networks

Optimal topologies for wireless sensor networks

ISBN: (纸本)0819455644

Since untethered sensor nodes operate on battery, and because they must communicate through a multi-hop network, it is vital to optimally configure the transmit power of the nodes both to conserve power and optimize spatial reuse of a shared channel. Current topology control algorithms try to minimize radio power while ensuring connectivity of the network. We propose that another important metric for a sensor network topology will involve consideration of hidden nodes and asymmetric links. Mnimizing the number of hidden nodes and asymmetric links at the expense of increasing the transmit power of a subset of the nodes may in fact increase the longevity of the sensor network. In this paper we explore a distributed evolutionary approach to optimizing this new metric. Inspiration from the Particle Swarm Optimization technique motivates a distributed version of the algorithm. We generate topologies with fewer hidden nodes and asymmetric links than a comparable algorithm and present some results that indicate that our topologies deliver more data and last longer.
