Abstract:
1. A method comprising: determining, by a processor, a number of contending nodes and a number of colliding nodes for a plurality of links; determining, using the processor, a capacity of each of the plurality of links; summing, using the processor, traffic demand of each of the plurality of links divided by throughput of each of the plurality of links to form a cost function for a network; searching, using the processor through one of a group consisting of a plurality of frequency assignments, a plurality of transmit powers, and a plurality of clear channel assessment levels to obtain a global minimum for the cost function; wherein searching through the plurality of clear channel assessment levels further comprises: calculating contentions and collisions, using the processor, based on transmit power, path loss and clear channel assessment for a plurality of clear channel assessment values between a minimum value and a maximum value; and selecting, using the processor, a clear channel assessment value that minimizes the cost function; wherein the access point to access point path losses are known.
