Gallium Arsenide (GaAs) based microsensors, analog readout electronics, analog to digital converters and digital signal processors have been in development. Microsensors include accelerometers, infrared sensors, and micromachines with high speed sensing response, extreme temperature operation, and high radiation hardness.
Networking together hundreds or thousands of cheap microsensor nodes allows users to accurately monitor a remote environment by intelligently combining the data from the individual nodes. These networks require robust wireless communication protocols that are energy efficient and provide low latency. In this paper, we develop and analyze low-energy adaptive clustering hierarchy (LEACH), a proto...
The increasing threat of microbial weapons of mass destruction (WMD) creates a critical need for rapid development and deployment of target-specific microsensor detection systems. Next-generation biosensor-dependent technologies must incorporate intelligence into the microsensor platform, enabling the execution of complex detection tasks, such as systematic identification and classification of ...
Microsel1sors operate under severe energy cOllstraints a'nd should be deployed in large numbers Wilhou! any pre-col/figuration. The maill contribution of this paper is a generalized selfclustering protocol, called Low-energy Localized Clustering (LLC).lt iucorporates the bestfeatllres of two other recently proposed self-configurirzg protocols for sensor networks: the Localized protocol and the ...
Gallium arsenide (GaAs) based microaccelerometers are being developed for guidance and navigation subsystems, and various microsensor systems. The microaccelerometer is a microelectromechanical system (MEMS) micromachined on top of GaAs substrate or GaAs integrated cirwits. The MEMS accelerometer is integrated on the same chip as the GaAs readout circuit and the GaAs analog to digital converter...
