Distributed protocol for use in a wireless network
First Claim
1. A Dynamic Radio Control Protocol for use by devices in a wireless communications environment wherein multiple channels are available for communication, comprising:
- exchange of Claim messages between devices, wherein each device uses the claim messages it sends and receives to select a channel on which to communicate;
exchange of Announce messages between devices, wherein some devices send Announce messages to indicate their presence and their protocol capability to other devices;
exchange of Bid messages between devices, wherein a sending device sends a Bid message to a receiving device to indicate that the sending device desires to communicate in the wireless communications environment via the receiving device;
exchange of Accept messages between devices, wherein a sending device sends an Accept message to a receiving device in response to a Bid message to indicate that the sending device will allow the receiving device to communicate in the wireless communications environment via the sending device.

Abstract
The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.
