Medium Access Control with Coordinated Adaptive Sleeping for Wireless Sensor Networks

by Wei Ye, John Heidemann, Deborah Estrin - IEEE/ACM Transactions on Networking , 2004
"... This paper proposes S-MAC, a medium access control (MAC) protocol designed for wireless sensor networks. Wireless sensor networks use battery-operated computing and sensing devices. A network of these devices will collaborate for a common application such as environmental monitoring. We expect senso ..."

The Player/Stage Project: Tools for Multi-Robot and Distributed Sensor Systems

by Brian P. Gerkey, Richard T. Vaughan, Andrew Howard - In Proceedings of the 11th International Conference on Advanced Robotics , 2003
"... This paper describes the Player/Stage software tools applied to multi-robot, distributed-robot and sensor network systems. Player is a robot device server that provides network transparent robot control. Player seeks to constrain controller design as little as possible; it is device independent, non ..."

The PHANToM haptic interface: A device for probing virtual objects

by Thomas H. Massie, J. K. Salisbury - Proceedings of the ASME Dynamic Systems and Control Division , 1994
"... This paper describes the PHANTOM haptic interface- a device which measures a user’s finger tip position and exerts a precisely controlled force vector on the finger tip. The device has enabled users to interact with and feel a wide variety of virtual objects and will be used for control of remote ma ..."

The Cricket Location-Support System

by Nissanka B. Priyantha, Anit Chakraborty, Hari Balakrishnan , 2000
"... This paper presents the design, implementation, and evaluation of Cricket, a location-support system for in-building, mobile, locationdependent applications. It allows applications running on mobile and static nodes to learn their physical location by using listeners that hear and analyze informatio ..."

to advertise this information to; it does not rely on any centralized management or control and there is no explicit coordination between beacons; it provides information to devices regardless of their type of network connectivity; and each Cricket device is made from off-the-shelf components and costs less

The design of an acquisitional query processor for sensor networks

by Samuel Madden, Michael J. Franklin, Joseph M. Hellerstein, Wei Hong - In SIGMOD , 2003
"... We discuss the design of an acquisitional query processor for data collection in sensor networks. Acquisitional issues are those that pertain to where, when, and how often data is physically acquired (sampled) and delivered to query processing operators. By focusing on the locations and costs of acq ..."
Abstract - Cited by 523 (25 self) - Add to MetaCart
of acquiring data, we are able to significantly reduce power consumption over traditional passive systems that assume the a priori existence of data. We discuss simple extensions to SQL for controlling data acquisition, and show how acquisitional issues influence query optimization, dissemination

How To Prove Yourself: Practical Solutions to Identification and Signature Problems

by Amos Fiat, Adi Shamir , 1987
"... In this paper we describe simple identification and signature schemes which enable any user to prove his identity and the authenticity of his messages to any other user without shared or public keys. The schemes are provably secure against any known or chosen message attack ff factoring is difficult ..."
Abstract - Cited by 1028 (1 self) - Add to MetaCart
is difficult, and typical implementations require only 1% to 4% of the number of modular multiplications required by the RSA scheme. Due to their simplicity, security and speed, these schemes are ideally suited for microprocessor-based devices such as smart cards, personal computers, and remote control system.q.

Cognitive networks

by Ryan W. Thomas, Luiz A. DaSilva, Allen B. MacKenzie - IN PROC. OF IEEE DYSPAN 2005 , 2005
"... This paper presents a definition and framework for a novel type of adaptive data network: the cognitive network. In a cognitive network, the collection of elements that make up the network observes network conditions and then, using prior knowledge gained from previous interactions with the network ..."
Abstract - Cited by 1106 (7 self) - Add to MetaCart
is needed to translate the user’s end-to-end goals into a form understandable by the cognitive process. The cognitive network also depends on a Software Adaptable Network that has both an external interface accessible to the cognitive network and network status sensors. These devices are used to provide

Standards for Traffic Control Devices”

Bricks: Laying the foundations for graspable user interfaces

by George W. Fitzmaurice , 1995
"... We introduce the concept of Graspable User Interfaces which allow direct control of electronic or virtual objects through physical handles for control. These physical artifacts are essentially new input devices which can be tightly coupled or “attached ” to virtual objects for manipulation or for ex ..."
