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

On the Connectivity of Hierarchical Directional Optical Sensor Networks
U.N. Okorafor,Deepa Kundur +1 more
TL;DR: Probabilistic bounds on network parameters for hierarchical connectivity in OSNs are provided, using a novel approach that directly considers directionality, and are proved on the jointly minimum radius of communication as well as angle of the communication sector required for network connectivity.

An Optical Transceiver Powered by On-Chip Solar Cells for IoT Smart Dusts With Optical Wireless Communications
TL;DR: It is successfully demonstrated that the transceiver scavenged the power from a 670-nm modulated laser beam sent by a base station, extracted clock signal and the encoded data from the beam, decoded two designed instructions, switched theLC in the MRR and sent responses back to the BS.

Location-Aided Topology Discovery for Wireless Sensor Networks
TL;DR: A location-aided topology discovery algorithm (LAD) that requires O(log( |M|)) data units per node in common cases, and O(|M|) data unitsper node in the worst case, where M is the set of directly communicable neighbors of a particular node.

An Energy-Efficient Clustering Algorithm for Wireless Sensor Network
Ying Liang,Hang Li +1 more
TL;DR: Simulation results demonstrate that the proposed approach to clustering for long-lived wireless sensor networks is effective in prolonging longer lifetime and higher throughput than the current important clustering protocols.

Introduction to Mobile Ad Hoc Networks
TL;DR: This book demonstrates how metaheuristics and evolutionary algorithms can be used to help provide low-cost operations in the optimization process—allowing designers to put some “intelligence” or sophistication into the design.

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.
