System architecture directions for networked sensors
- IN ARCHITECTURAL SUPPORT FOR PROGRAMMING LANGUAGES AND OPERATING SYSTEMS
, 2000
"... Technological progress in integrated, low-power, CMOS communication devices and sensors makes a rich design space of networked sensors viable. They can be deeply embedded in the physical world or spread throughout our environment. The missing elements are an overall system architecture and a methodo ..."

in 178 bytes of memory, propagates events in the time it takes to copy 1.25 bytes of memory, context switches in the time it takes to copy 6 bytes of memory and supports two level scheduling. The analysis lays a groundwork for future architectural advances.
Cooperative diversity in wireless networks: efficient protocols and outage behavior
- IEEE TRANS. INFORM. THEORY
, 2004
"... We develop and analyze low-complexity cooperative diversity protocols that combat fading induced by multipath propagation in wireless networks. The underlying techniques exploit space diversity available through cooperating terminals’ relaying signals for one another. We outline several strategies ..."

A Frequency-Dependence Model for the Ultra-Wideband Channel based on Propagation Events
"... Abstract — While the frequency-dependence of the wireless channel may be negligible for narrow to wideband signals, it has been shown that modeling this dependence for bandwidths in excess of 2 GHz improves channel reconstruction up to 40%. Yet to our knowledge, only Molisch et al. have done so for ..."

according to the propagation events on their paths between the transmitter and receiver. We extract the model parameters from an extensive measurement campaign of 3000 channel frequency sweeps in three separate buildings combined with raytracing simulations, and show that ours fits the gathered data more
Information Diffusion through Blogspace
- In WWW ’04
, 2004
"... We study the dynamics of information propagation in environments of low-overhead personal publishing, using a large collection of weblogs over time as our example domain. We characterize and model this collection at two levels. First, we present a macroscopic characterization of topic propagation th ..."

through our corpus, formalizing the notion of long-running "chatter" topics consisting recursively of "spike" topics generated by outside world events, or more rarely, by resonances within the community. Second, we present a microscopic characterization of propagation from individual
SNUG Europe 2003 1 A Scalable Method of Propagating Event Messages
"... Abstract: Managing the flow of event messages between disparate classes of a testbench (RTL monitors, BFMs, simulation control classes) is a complex pro-cess, and one that can prove impossible if left until late in the design cycle. While ad hoc communication interfaces are simple enough to develop ..."

between classes, problems arise when classes that were not designed to communicate with each other suddenly have to. This paper presents a scalable method for propagating both blocking and nonblocking event messages throughout a test-bench. The technique is based on a software Design Pattern solution
Fast statistical timing analysis by probabilistic event propagation
- Proc. 2001 Design Automation Conference
, 2001
"... We propose a new statistical timing analysis algorithm, which produces arrival-time random variables for all internal signals and primary outputs for cell-based designs with all cell delays modeled as random variables. Our algorithm propagates probabilistic timing events through the circuit and obta ..."

AN EVENT SERVICE FOR THE PROPAGATION OF DATA
, 2004
"... hardware data are aggregated by event processing agents to produce complex events which supply summarized data to event channels for distribution to registered consumers, typically high-level software applications. The CORBA Notification Service, a recent extension to the Event Service, is also exam ..."
