Competition: BigBangBus.

A wireless bus based on flooding and the capture effect is proposed to achieve highly reliable broadcast communication in a Wireless Sensor Network (WSN) working in harsh environments in a multi-source-to-multi-sink topology where multiple hops are required (Fig. 1). Different sources access the medium without colliding using network-wide predefined time slots and frequency channels. Frequency-, spatial- and time-diversity is exploited using redundant retransmissions.
