TLDR
This work reviews the key elements of the emergent technology of “Smart Dust” and outlines 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.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.read more

A sensor selection method considering communication delays
Shingo Kagami,Masatoshi Ishikawa +1 more
TL;DR: A sensor selection method for distributed real-time sensing is proposed where the effect of communication delays is taken into account and an algorithm is developed that calculates mutual information between an observation and the state to be estimated, which provides a criterion for sensor selection.

Energy-efficient node scheduling models in sensor networks with adjustable ranges
Jie Wu,Shuhui Yang +1 more
TL;DR: The objective is to minimize the overlapped sensing area of sensor nodes, thus to reduce the overall energy consumption by sensing and communication to prolong the whole network's life time, and at the same time to achieve the high ratio of coverage.
