Abstract
An example device detects a pattern of medium reservations by a first wireless device by detecting that the first wireless device has indicated a reservation duration that meets or exceeds a threshold duration value. Responsive to detecting the pattern of medium reservations, the device provides a mitigation operation to prevent a second wireless device from yielding the medium to the first wireless device.
Claims24
A method comprising:
- detecting a pattern of medium reservations by a first wireless device comprising detecting that the first wireless device has indicated a reservation duration that meets or exceeds a threshold duration value, wherein the reservation duration is to reserve a medium, wherein the detecting that the first wireless device has indicated the reservation duration that meets or exceeds the threshold duration value comprises detecting that a sum of reservation durations associated with two or more frames received from the first wireless device meets or exceeds the threshold duration value;
- and
- responsive to detecting the pattern of medium reservations, providing a mitigation operation to prevent a second wireless device from yielding the medium to the first wireless device.
A method comprising:
- detecting a pattern of medium reservations by a first wireless device comprising detecting that the first wireless device has indicated a reservation duration that meets or exceeds a threshold duration value, wherein the reservation duration is to reserve a medium, wherein detecting the pattern of medium reservations by the first wireless device comprises detecting that a number of frames received from the first wireless device indicate the reservation duration that meets or exceeds the threshold duration value and that the number of frames meets or exceeds a threshold number of frames;
- and
- responsive to detecting the pattern of medium reservations, providing a mitigation operation to prevent a second wireless device from yielding the medium to the first wireless device.
A method comprising:
- detecting a pattern of medium reservations by a first wireless device comprising detecting that the first wireless device has indicated a reservation duration that meets or exceeds a threshold duration value, wherein the reservation duration is to reserve a medium;
- determining an interval of a plurality of frames received from the first wireless device;
- responsive to detecting the pattern of medium reservations, providing a mitigation operation to prevent a second wireless device from yielding the medium to the first wireless device, wherein providing the mitigation operation comprises using the determined interval to determine a time to transmit a mitigation signal to interfere with reception of at least one of the plurality of frames by the second wireless device;
- and
- transmitting the mitigation signal to the second wireless device at the determined time.
