Abstract
A first wireless node provides a method of avoiding multiple access collision in a wireless network. The system receives a request to send data from a second wireless node (405) and determines if the system is receiving data from a third node (410). The system transmits a non-authorization message if the system is receiving data from the third node (415). If, however, the system is not receiving data from the third node, the system transmits an authorization message to the first wireless node (420). The system receives data from the second node in response to the authorization message (425) and then transmits an acknowledgment message to the second node acknowledging receipt of the data (435).
