Patent ID: 7397814

Claim:
A method of controlling an access of a station to a shared wireless media comprising: calculating a first probability value representing a probability of a first station to transmit a data packet within a desired time slot of a contention window by counting the data packets transmitted from said first station within any time slot of said contention window to provide a third number, counting the data packets transmitted from any station in said shared wireless media within any time slot of said contention window to provide a fourth number and dividing said third number by said fourth number; calculating a second probability value representing a probability of said data packet when transmitted by the first station within the desired time slot of said contention window to collide with at least one other data packet transmitted by a second station; and transmitting a data packet from said first station to a shared wireless media based on a collision rate parameter calculated from said first and said second probability values, wherein said second probability value is calculated by: counting data packets transmitted within said desired time slot to provide a first number; counting data packets transmitted within said desired time slot and within at least one other time slot of said contention window to provide a second number; and dividing the first number by the second number.
