A research paper from Nokia Research Center in Berkeley received a best paper award at PIMRC 2012 in Sydney, Australia. Our paper titled “Simultaneous Polling Mechanism for low Power Sensor Networks using ZC Sequences”, authored by Taejoon Kim, Sayantan Choudhury, Zhong-Yi Jin, Klaus Doppler and Chittabrata Ghosh, solves a major challenge in low power sensor networks on how to collect data from a large number of sensors with low latency. In existing Wi-Fi networks, the access point needs to poll the sensor nodes sequentially resulting in longer collection time of data. We propose a physical layer technique that parallelizes the polling response from multiple sensors (so called parallel acknowledgment) in order to decrease the latency. PIMRC is one of the premier conferences in the wireless research arena and is a flagship conference of the IEEE Communication Society.
