1. A method for actively evaluating and adjusting device energy consumption in a personal area network (PAN), the PAN comprising a Bluetooth wireless communications network, the method comprising:

  • polling devices in the PAN to determine respective energy metrics, the polling comprising;

    establishing a piconet with one device functioning as a master device and at least one other device functioning as a slave device,determining if devices are powered by battery, and,identifying the battery charge status for each device powered by battery; and

    establishing network communications between devices using the energy metrics, the establishing network communications comprising;

    establishing network communications rules between devices, via the master device to optimize device battery life comprising;

    determining a priority of operation for the devices in the network;

    establishing network communication rules in response to device battery charge status and device priority of operation, andminimizing energy consumption for devices with low energy metrics.
