Method of beacon exchange between devices with asymmetric links and system using the method
First Claim
1. A method of beacon exchange for allowing a low power device having an asymmetric link to access a wireless network to exchange beacons with any one of a plurality of normal power devices in the wireless network, the method comprising:
- confirming whether the low power device has an asymmetric link with a normal power device, when the low power device receives a beacon of the normal power device, based on the received beacon;
negotiating with at least one relay device so that the low power device requests a relay with respect to the asymmetric link, when the low power device has the asymmetric link with the normal power device; and
the at least one relay device noting a result of the negotiating to the low power device and to a normal power device with which the low power device is desired to communicate, based on the result of the negotiating.

Abstract
A method and a system for using the method are provided. The method and system allow a low power device having an asymmetric link to access a wireless network to exchange beacons with any one of a plurality of normal power devices in the wireless network. The method includes the steps of confirming whether the low power device has the asymmetric link with the normal power device, when the low power device receives a beacon of the low power device based on the received beacon; negotiating with at least one relay device so that the low power device requests a relay with respect to the asymmetric link, when the low power device has an asymmetric link with the normal power device; and at least one relay device noting a result of the negotiation to the low power device and a normal power device with which the low power device is intending to communicate, based on the result of the negotiation.

13. A system of beacon exchange for allowing a device having an asymmetric link to access a wireless network exchanges beacons with any one of a plurality of devices in the wireless network, the system comprising:
-
a normal power device in the wireless network; a low power device for confirming whether to have the asymmetric link with the normal power device, when receiving a beacon of the normal power device, based on the received beacon, and for requesting a relay with respect to the asymmetric link, when having the asymmetric link with the normal power device; and a relay device for noting a result of the requesting to the low power device and a normal power device with which the low power device is desired to communicate, according to the request of the low power device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
