Improvement to efficient counter-based broadcast scheme through random assessment delay adaptation for MANETs [PDF]

open access: yes, 2008
Flooding, the process in which each node retransmits every uniquely received packet exactly once is the simplest and most commonly used mechanism for broadcasting in mobile ad hoc networks (MANETs). Despite its simplicity, it can result in high redundant

Broadcast communication by system frequency modulation [PDF]

open access: yes2012 IEEE Third International Conference on Smart Grid Communications (SmartGridComm), 2012
Load controllers available today can measure AC system frequency and react to frequency deviations. A system operator can communicate to frequency sensitive loads by changing the set-points of the system's dispatchable frequency regulation resources.
