Abstract
Systems, processes and methods are described for increasing the reliability of packet delivery while reducing end-to-end latency and power consumption in a low power wireless network. The packet is forwarded during a transmit timeslot utilizing link layer broadcast transmissions. A preset number of retransmission timeslots are provided to retransmit the packet. To reduce energy consumption for recipients, a recipient can enter a sleep mode after receiving the packet for the remaining retransmit timeslots.
