1. A power sharing method for a wireless device, sharing power between the wireless device and at least one neighboring wireless device, the method comprising:
- scanning, by the wireless device, the at least one neighboring wireless device;
monitoring the at least one neighboring wireless device to determine whether to share the power with the at least one neighboring wireless device;
determining roles of the wireless device and the at least one neighboring wireless device, respectively as either a power supplier or a power consumer;
determining a power sharing scheme and selectively sharing power between the wireless device and the at least one neighboring wireless device based on the determined roles and the determined power sharing scheme, including the wireless device receiving power when in the power consumer role from the at least one neighboring wireless device that is in the power supplier role;
receiving, from the at least one neighboring wireless device, a descriptor of the at least one neighboring wireless device; and
generating a neighbor table based on the descriptor of the at least one neighboring wireless device,wherein the generating of the neighbor table comprises;
adding, to the neighbor table, information on a strength of a signal received from the at least one neighboring wireless device, and information on an amount of time elapsed after the descriptor of the at least one neighboring wireless device is received; and
adding, to the neighbor table and based on a descriptor received from another neighboring wireless device, information on a strength of a signal received from the other neighboring wireless device, and information on an amount of time elapsed after the descriptor of the other neighboring wireless device is received.
