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

Random consensus protocol in large-scale networks
Zhipu Jin,Richard M. Murray +1 more
TL;DR: This paper introduces a deterministic principle to locate certain "chosen nodes" in the network and add "virtual" shortcuts among them so that the number of iterations to achieve average consensus drops dramatically, and proposes a random consensus protocol, in which virtual shortcuts are implemented by random routes.

Body Dust: Well Beyond Wearable and Implantable Sensors
TL;DR: The Body Dust concept definitely represents the future of humans monitoring, still opens to scientific explorations and the definition of the still-open challenges for realizing motes that could spread in human body as thousands of individual sensors in a kind of sensing active network capable to provide telemetry from inside the body.

On the Relevance of Node Isolation to the K-Connectivity of Wireless Optical Sensor Networks
U.N. Okorafor,Deepa Kundur +1 more
TL;DR: This study investigates node isolation in wireless optical sensor networks (WOSNs) as a topology attribute for network connectivity and derives a generalized analytical expression relating the probability that no node is isolated to the physical layer parameters of node density, transmitter radius, and angular beam width.

Optimizing the code rate for achieving energy-efficient wireless communications
TL;DR: The results show that codes with low code rate are optimal for performing long-range communications, while is better to use less coding redundancy when the transmission distance is short, and the transmission range of a low-power communication device can be increased.

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.
