Methods and arrangements for channel access in wireless networks

A method comprising:

• receiving, by a medium access control sublayer logic from a physical layer device, a frame comprising parameter records to change default management information base (MIB) attribute values for an enhanced distributed channel access (EDCA) Parameter Set element having parameter values for defining access categories of data traffic including best efforts traffic and sensor traffic, the parameter values including arbitration interframe space numbers and one or more contention window values for the access categories, wherein an arbitration interframe space number setting for a sensor access category is lower than an arbitration interframe space number for a best efforts access category for the default MIB attribute value, wherein the sensor access category provides the sensor traffic with priority over the best efforts traffic during competition in a first round of a contention window;
• and
• storing, by the medium access control sublayer logic, based upon the frame, the parameter record for the access categories for the sensor traffic in a management information base memory.

A device comprising:

• a medium access control sublayer logic coupled with a memory to receive a frame from a physical layer device comprising parameter records to change default management information base (MIB) attribute values for an enhanced distributed channel access (EDCA) Parameter Set element having parameter values for defining access categories of data traffic including best efforts traffic and sensor traffic, the parameter values including arbitration interframe space numbers and one or more contention window values for the access categories, wherein an arbitration interframe space number setting for a sensor access category is lower than an arbitration interframe space number for a best efforts access category for the MIB attribute value, wherein the sensor access category provides the sensor traffic with priority over the best efforts traffic during competition in a first round of a contention window;
• and
• the memory to store by the medium access control sublayer logic, based upon the frame, the parameter record for the access categories for the sensor traffic in a management information base.
