Abstract
The broadcast nature of wireless communication may be utilized by transmitting a packet frame identifying at least one relay node that can transmit the packet frame without transmitting an acknowledgement frame confirming receipt of the packet frame by a respective relay node. A relay node may cancel a relay obligation to transmit a packet frame based on detecting transmission of the packet frame by another node or based on detection of an acknowledgement frame confirming that a destination node received the packet frame. A transmission chain corresponding to the transmission of a packet frame may be assigned a priority. Alternatively or in addition, a relay node within a transmission chain may be assigned a priority. A priority may determine the amount of delay inserted prior to transmitting a packet frame.
