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 5.58 nW Crystal Oscillator Using Pulsed Driver for Real-Time Clocks
TL;DR: A 5.58 nW real-time clock using a crystal oscillator is presented, in which the amplifier used in a traditional circuit is replaced with pulsed drivers and an extremely low oscillation amplitude results in low-power operation.
Bluetooth Based Wireless Sensor Networks –Implementation Issues and Solutions
TL;DR: The main principles, applications and issues of Bluetooth based wireless sensor networks, as well as an implementation of a simple Bluetooth based sensor network are described and the main problems experienced during the implementation and applied solutions are presented.
Challenges in Flexible Aggregation of Pervasive Data
TL;DR: The construction of an aggregation system to manage shared resources and facilitate the writing of applications is proposed, which combines the collection of raw data from pervasive data sources, the flexible, programmable composition of the raw data into less voluminous refined data, and the timely delivery of the refined data to data consumers.

Altruists in the PicoRadio sensor network
TL;DR: It is shown that the altruist approach can achieve significant gains in terms of network lifetime over the already lifetime-optimized EAR protocol of PicoRadio.

Hop count optimal position based packet routing algorithms for ad hoc wireless networks with a realistic physical layer
TL;DR: In this paper, the authors proposed a hop count optimal, greedy, localized routing algorithm (IHCR) for ad hoc networks, where the packet is forwarded to the neighbor closest to the destination among neighbors that are within distance tR.

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.
Book
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.
