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

Maté: a tiny virtual machine for sensor networks
Philip Levis,David E. Culler +1 more
TL;DR: Maté's concise, high-level program representation simplifies programming and allows large networks to be frequently reprogrammed in an energy-efficient manner; in addition, its safe execution environment suggests a use of virtual machines to provide the user/kernel boundary on motes that have no hardware protection mechanisms.

A pairwise key pre-distribution scheme for wireless sensor networks
TL;DR: This paper proposes a new key pre-distribution scheme, which substantially improves the resilience of the network compared to the existing schemes, and exhibits a nice threshold property: when the number of compromised nodes is less than the threshold, the probability that any nodes other than these compromised nodes are affected is close to zero.

A coverage-preserving node scheduling scheme for large wireless sensor networks
Di Tian,Nicolas D. Georganas +1 more
TL;DR: A node-scheduling scheme, which can reduce system overall energy consumption, therefore increasing system lifetime, by turning off some redundant nodes, and guarantees that the original sensing coverage is maintained after turning off redundant nodes.

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.
