From motes to Java stamps: smart sensor network testbeds
نویسندگان
چکیده
We have proposed Smart Sensor Networks (S-Nets) as an architecture and set of distributed algorithms to extract, interpret and exploit networked sensor devices. Heretofore, the development of this approach has been done in simulation. In this paper, we describe two complementary implementations of S-Nets: (1) on a set of Berkeley motes comprised of low-power 8-bit, 128Kb memory processors, communication devices and sensors, and (2) on a set of JStamps having 32-bit controllers, 2Mb of memory and native execution Java hardware.

Testing Wireless Sensor Networks with Hybrid Simulators
Software development for Wireless Sensor Networks (WSNs) is challenging due to characteristics of sensor nodes and the environment they are deployed in. Testing software in a real WSN testbed allows users to get reliable test results. However, real testbeds become more expensive as the number of sensor nodes in the network grows. Simulation tools are alternatives to real testbeds. They are chea...
متن کاملA “Smart Dust”-Based Road Condition Monitoring System: Performance of A Small Wireless Sensor Network using Surge Time Synchronization
Pavement maintenance is vital for travel safety and thus detecting dangerous road conditions in real-time fashion is desirable. Using off-the-shelf sensors and a wireless sensor network product to detect such conditions at a low cost poses many challenges. To meet these challenges, a “Smart Dust” (i.e., the Mica2 Motes)-based sensor network is adopted in a proof-of-concept study to monitor pave...

1.0 Project Goal Smart Dust motes are self-contained, millimeter-scale sensing and communication platforms for a massively distributed sensor network [61,71]. They will ultimately be around the size of a grain of sand and will contain micro/nano sensors, computational ability, bi-directional wireless communications, and a power supply. There exist endless possibilities for the applications of t...
متن کاملDiscovery, Localization and Recognition of Smart Objects by a Mobile Robot
This paper presents a robotic system that exploits Wireless Sensor Network (WSN) technologies for implementing an ambient intelligence scenario. We address the problems of robot object discovery, localization, and recognition in a fully distributed way. We propose to embed some memory, some computational power, and some communication capability in the objects, by attaching a WSN mote to each ob...
متن کاملSenQ: An Extensible Query System for Streaming Data in Heterogeneous Interactive Wireless Sensor Networks
Interactive wireless sensor networks (IWSNs) manifest diverse sensors and dynamic user interactions. To support data collection and processing in such heterogeneous systems, we created SenQ: an extensible query system and network protocol for streaming sensor data. We evaluate it using a set of devices we developed for physiological, environmental, and activity monitoring in the context of assi...
