Universal Hash Functions for Emerging Ultra-Low-Power Networks
"... Abstract — Message Authentication Codes (MACs) are a valuable tool for ensuring the integrity of messages. MACs may be built around a keyed hash function. In this paper, we propose three variations on NH (a universal hash function explored in UMAC [1]), namely PH, PR and WH. Our main motivation was ..."

was to prove that universal hash functions can be employed to provide provable security in ultra-low-power applications such as the next generation self-powered sensor networks. The first hash function we propose, i.e. PH, produces a hash of length 2w and is shown to be 2 −w-almost universal. The other two
Telos: Enabling Ultra-Low Power Wireless Research
, 2005
"... We present Telos, an ultra low power wireless sensor module (“mote”) for research and experimentation. Telos is the latest in a line of motes developed by UC Berkeley to enable wireless sensor network (WSN) research. It is a new mote design built from scratch based on experiences with previous mote ..."

Versatile Low Power Media Access for Wireless Sensor Networks
, 2004
"... We propose B-MAC, a carrier sense media access protocol for wireless sensor networks that provides a flexible interface to obtain ultra low power operation, effective collision avoidance, and high channel utilization. To achieve low power operation, B-MAC employs an adaptive preamble sampling scheme ..."

What is Twitter, a Social Network or a News Media?
"... Twitter, a microblogging service less than three years old, commands more than 41 million users as of July 2009 and is growing fast. Twitter users tweet about any topic within the 140-character limit and follow others to receive their tweets. The goal of this paper is to study the topological charac ..."
