Abstract
Large-scale networks of wireless sensors are becoming an active topic of research. Advances in hardware technology and engineering design have led to dramatic reductions in size, power consumption and cost for digital circuitry, wireless communications and Micro ElectroMechanical Systems
(MEMS). This has enabled very compact, autonomous and mobile nodes, each containing one or more sensors, computation and communication capabilities, and a power supply.
The missing ingredient is the networking and applications layers needed to harness this revolutionary capability into a complete system. We review the key elements of the emergent technology of “Smart Dust” and outline the research challenges they present to the mobile networking and systems community, which must provide coherent connectivity to large numbers of mobile network nodes co-located within a small volume.

Introduction
As the research community searches for the processing platform beyond the personal computer, networks of wireless sensors have become quite interesting as a new environment in which to seek research challenges. These have been enabled by the rapid convergence of three key technologies: digital circuitry, wireless communications, and Micro ElectroMechanica1 Systems (MEMS). In each area, advances in hardware technology and engineering design have led to reductions in size, power consumption, and cost. This has enabled remarkably compact, autonomous nodes, each containing one or more sensors, computation and communication capabilities, and a power supply.
Berkeley’s Smart Dust project, led by Professors Pister and
Kahn, explores the limits on size and power consumption in autonomous sensor
