Poster abstract: The low-power wireless bus: Simplicity is (again) the soul of efficiency

Abstract

We present the low-power wireless bus (LWB), a simple yet efficient communication support for low-power wireless networks. The LWB maps different communication demands onto fast Glossy network flooding, effectively turning the wireless network into a bus-like infrastructure. The LWB requires no information of the network topology, thus drastically reducing the control overhead of common solutions such as route maintenance, and natively supports many-to-many communication and mobile nodes in addition to more traditional static, one-to-many scenarios. For instance, experiments on a 90-node testbed show that on average the LWB reduces packet loss by a factor of 231 and energy consumption due to communication by a factor of 11 compared to a state-of-the-art many-to-many routing protocol.
