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

Detection of Digitally Phase-Modulated Signals Utilizing Mechanical Vibration of CNT Cantilever
TL;DR: The effectiveness of the nanoscale phase detector is numerically demonstrated, and the gain relative to the demodulation achieved using a conventional simple correlator is established.
Barrier Coverage in Wireless Sensor Networks
TL;DR: A novel directional barrier graph model is introduced and it is proved that the minimum cost of mobile sensors required to form a barrier with stationary sensors is the length of the shortest path from the source node to the destination node on the graph.

The DARPA packet radio network protocols
J. Jubin,J.D. Tornow +1 more
TL;DR: The algorithms are described and illustrated how the PRNET provides highly reliable network transport and datagram service, by dynamically determining optimal routes, effectively controlling congestion, and fairly allocating the channel in the face of changing link conditions, mobility, and varying traffic loads.

The Diamond Age
TL;DR: The Diamond Age as discussed by the authors is a major novel from one of the most visionary writers of our time, with a protagonist who breaks the rigorous moral code of his tribe, the powerful Neo-Victorians, by making an illicit copy of a state-of-the-art interactive device called a young lady's illustrated primer.
