...While pioneering projects have been proposed for lowduty-cycle unicasts [8, 24, 47], research is surprisingly inadequate for low-duty-cycle flooding, an important function for disseminating network-wide commands, alerts and configurations [11], time synchronization [25], and code binaries [14]....

...We note that many MAC protocols, such as B-MAC [18], S-MAC [25], FPA [13] and SCP-MAC [26], effectively deal with the issues of lossy radio links through FEC/ARQ and reduce duty-cycle through the Low-Power-Listening (LPL) [18]....
