A substantial percentage of links in wireless networks, especially low-power ones, is asymmetric. For the low-quality direction of asymmetric links, we observe based on testbed ex...
— The recent researches in wireless networks prompt the opportunistic transmission that exploiting channel fluctuations to improve the overall system performance. In wireless ad...
—We investigate location distinction, the ability of a receiver to determine when a transmitter has changed location, which has application for energy conservation in wireless se...
—Innovation in gateways for data gathering sensor networks has lagged compared to advances in mote-class devices, leaving us with a limited set of options for deploying such syst...
Sensor network nodes exhibit characteristics of both embedded systems and general-purpose systems. They must use little energy and be robust to environmental conditions, while als...
