Claim of US Patent No. 9,860,851

1. An apparatus for wireless communication, comprising:
a processing system configured to:
determine a first list wherein the first list includes wireless nodes detected by a first wireless node;
receive a second list from a second wireless node, wherein the second list includes wireless nodes detected by the second
wireless node;

detect a condition experienced by only one of the first and the second wireless nodes, wherein the condition is detected by
determining that either (1) the first list includes the second wireless node and the second list does not include the first
wireless node or (2) the second list includes the first wireless node and the first list does not include the second wireless
node;

in response to the detected condition, select an operational parameter from a plurality of operational parameters that includes
(1) virtual carrier sensing protocol and (2) transmission power, wherein the selection is based on wireless traffic at the
first and the second wireless nodes; and

modify the selected operational parameter of the first or the second wireless node such that both the first and second wireless
nodes experience the condition or neither the first nor the second wireless node experiences the condition, wherein the selected
operational parameter is modified by (1) requiring use of the virtual carrier sensing protocol at the first wireless node
or at the second wireless node if the virtual carrier sensing protocol is the selected operational parameter, or (2) requiring
an adjustment of the transmission power at the first wireless node or at the second wireless node if the transmission power
is the selected operational parameter.
