Abstract: A system and method for reducing energy consumption in a wireless network. In one embodiment, a system includes a network coordinator configured to manage access to a wireless network. The network coordinator includes a controller. The controller is configured to define a channel hopping list that specifies on which channel a beacon signal is transmitted in each slot frame of the wireless network. The controller is also configured to set a number of time slots in each slot frame based on a length of the channel hopping list. The controller is further configured to transmit a first beacon signal in each slot frame on a channel specified by the channel hopping list. The number of slots in each slot frame causes the first beacon signal to be transmitted on a same channel in each slot frame.

Abstract: A system and method for optimizing power consumption of energy harvesting nodes in a wireless sensor network. In one embodiment, a system includes a network coordinator. The network coordinator includes a wireless transceiver and a controller. The wireless transceiver is configured to provide access to the wireless sensor network. The controller is configured to determine whether a wireless device that is wirelessly communicating with the network coordinator is powered via energy harvesting. The controller is also configured to schedule, based on a determination that the wireless device is powered via energy harvesting, the wireless device to communicate via the wireless sensor network using a priority timeslot of a superframe of the wireless sensor network. The priority timeslot is a timeslot occurring in an initial portion of the superframe.
