  The low-power wireless bus (LWB) is a highly efficient communication protocol
for wireless sensor networks (WSN). However, a lack of open implementation for
this protocol prompted the implementation of the protocol for the most common
platform of WSN related research, the sky nodes using the Contiki operating
system. This document provides the detailed description of the implementation.
  A forwarder-selection mechanism is developed to improve energy-efficiency of
LWB in data collection scenario. The implementation also consists the forwarder
selection mechanism. One can either use the original features of LWB or enforce
the forwarder selection mechanism.
