Maté: A Tiny Virtual Machine for Sensor Networks

by Philip Levis, David Culler , 2002
"... Composed of tens of thousands of tiny devices with very limited resources ("motes"), sensor networks are subject to novel systems problems and constraints. The large number of motes in a sensor network means that there will often be some failing nodes; networks must be easy to repopu-late. ..."

Protocols for self-organization of a wireless sensor network

by Katayoun Sohrabi, Jay Gao, Vishal Ailawadhi, Gregory J Pottie - IEEE Personal Communications , 2000
"... We present a suite of algorithms for self-organization of wireless sensor networks, in which there is a scalably large number of mainly static nodes with highly constrained energy resources. The protocols further support slow mobility by a subset of the nodes, energy-efficient routing, and formation ..."

Tinydb: An acquisitional query processing system for sensor networks

by Samuel R. Madden, Michael J. Franklin, Joseph M. Hellerstein, Wei Hong - ACM Trans. Database Syst , 2005
"... We discuss the design of an acquisitional query processor for data collection in sensor networks. Acquisitional issues are those that pertain to where, when, and how often data is physically acquired (sampled) and delivered to query processing operators. By focusing on the locations and costs of acq ..."
