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

Collision-minimizing CSMA and its applications to wireless sensor networks
TL;DR: This work identifies several applications that motivate the event-driven workload and proposes a protocol that is optimal for this workload, named CSMA/p/sup, which is nonpersistent carrier sense multiple access with a carefully chosen nonuniform probability distribution p/sup that nodes use to randomly select contention slots.

Energy-efficient DSPs for wireless sensor networks
A. Wang,A. Chandrakasan +1 more
TL;DR: This work explores system partitioning between the sensor cluster and the base station, employing computation-communication tradeoffs to reduce energy dissipation and shows that system partitions within the cluster can also improve the energy efficiency by using dynamic voltage scaling (DVS).

Flexible power scheduling for sensor networks
TL;DR: A distributed on-demand power-management protocol for collecting data in sensor networks based on a novel, two-level architecture is proposed and shown how the protocol allows adaptive scheduling and enables a smooth trade-off between energy savings and latency.

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.
