Claim:
1. A system for providing a wireless asymmetric network architecture, comprising: a first hub having a wireless control device that is configured to control communications in the wireless asymmetric network architecture; and a first plurality of sensor nodes each having a wireless device with a transmitter and a receiver to enable bi-directional communications with the wireless control device of the first hub in the wireless asymmetric network architecture that is asymmetric in power availability between the first hub and at least one of the first plurality of sensor nodes having limited power availability and being primarily in a low-energy non-communicative state, wherein the wireless control device of the first hub is configured to detect a first communication from a first sensor node of the first plurality of sensor nodes, determine whether at least a portion of the first communication is unintelligible to circuitry of the first hub, determine whether a collision of communications transmitting at approximately the same time including the first communication transmitting from the first sensor node to the first hub and a second communication transmitting from a second sensor node to the first hub has likely occurred when the at least portion of the first communication is unintelligible to circuitry of the first hub, calculate next or subsequent receive windows for the first and second sensor nodes respectively, and transmit instructions during the next or subsequent receive windows to the first and second sensor nodes respectively to shift a receive window for the first sensor node with a first time period and to shift a receive window for the second sensor node with a different second time period when a collision of the first and second communications is determined to have likely occurred.
