Abstract
A network of nodes includes data nodes and at least one sink node to exchange packets between the sink node and the data nodes in a multi-hop manner. The data nodes include a battery powered node (BPN) having a transceiver, a memory, and a battery to provide energy to components of the BPN. The BPN includes a processor to determine a sleep schedule of the BPN independently from the sleep schedules of other data nodes and independently from commands transmitted by the sink node. The processor of the BPN switches the transceiver ON and OFF according to the sleep schedule to form an active period and a sleep period of the BPN. Also, the processor partitions at least part of the active period into a receiving (RX) period and a transmission (TX) period and causes the transceiver to transmit the data packets only during the TX period.
