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

Power-aware localized routing in wireless networks
Ivan Stojmenovic,Xu Lin +1 more
TL;DR: This work defines a new power-cost metric based on the combination of both node's lifetime and distance based power metrics and proposes power, cost, and power- cost GPS based localized routing algorithms, where nodes make routing decisions solely on the basis of location of their neighbors and destination.

Transactions papers a routing-driven Elliptic Curve Cryptography based key management scheme for Heterogeneous Sensor Networks
TL;DR: A novel routing-driven key management scheme, which only establishes shared keys for neighbor sensors that communicate with each other, which can provide better security with significant reductions on communication overhead, storage space and energy consumption than other key management schemes.

Toward self-organized mobile ad hoc networks: the terminodes project
TL;DR: It is shown that by their very nature, mobile ad hoc networks can bring a paradigm shift in the way networks are organized and operated, and can even lead to a fundamental change in the relationships between information technology and societal organization.

A protocol for tracking mobile targets using sensor networks
H. Yang,Biplab Sikdar +1 more
TL;DR: The proposed protocol, Distributed Predictive Tracking, is robust against node or prediction failures which may result in temporary loss of the target and recovers from such scenarios quickly and with very little additional energy use.

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.
