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

Energy-Efficient Estimation of Clock Offset for Inactive Nodes in Wireless Sensor Networks
TL;DR: The maximum-likelihood estimator (MLE) is derived for the clock offsets of the listening nodes located within the communication range of the active nodes by assuming an exponential link delay modeling, hence synchronizing with the reference node at a very low cost.

Fuzzy Self-Clustering for Wireless Sensor Networks
Yahya M. Tashtoush,M.A. Okour +1 more
TL;DR: A comparison was conducted and found that the new protocol distributes clusters uniformly as good as ACE protocol and prolong the network lifetime in magnitude of 100% more than ACE.
Universal Hashing for Ultra-Low-Power Cryptographic Hardware Applications
TL;DR: The main motivation was to prove that universal hash functions can be employed as underlying primitives of MACs in order to provide provable security in ultra-low-power applications such as the next generation self-powered sensor networks.

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.
