Abstract:
1. A computer-implemented method in which a computer system performs selective dynamic channel assignment in a wireless ad hoc network, the method comprising: determining a fixed channel assignment order for each link of the network, the fixed channel assignment order enabling simultaneous transmission without co-channel interference; loading a preference order for a node link, the preference order based on said fixed channel assignment order for the link, wherein said loading a preference order for the node link comprises dynamically determining at transmission time said preference order and wherein said preference order is further based on a combination of a percent of time a channel is reserved, reservation request successes on a channel, and reservation request failures on a channel; selecting a channel to use for the node link transmission in accordance with said preference order when the node link is ready for transmission; and determining whether the selected channel is available for the node link transmission, and when the selected channel is available then transmitting on said channel by said node and when the selected channel is not available then selecting a next channel in said preference order for said node and repeating said determining whether the selected channel is available.
