A.; “Low-power wireless sensor networks

Abstract- Wireless distributed microsensor systems will enable fault tolerant monitoring and control of a variety of appli-cations. Due to the large number of microsensor nodes that may be deployed and the long required system lifetimes, replacing the battery is not an option. Sensor systems must utilize the minimal possible energy while operating over a wide range of operating scenarios. This paper presents an overview of the key technolo-gies required for low-energy distributed microsensors. These include power aware computation/communication component technology, low-energy signaling and networking, system parti-tioning considering computation and communication trade-offs, and a power aware software infrastructure.
