System and method for contention control in wireless network |
摘要 |
A Quality-of-Service-enabled access point (QAP) broadcasts an initial number of time slots and an upper limit to a Quality-of-Service-enabled station (QSTA). The QSTA generates a random number between 0 and 1. The QSTA selects a time slot from the initial number of time slots for data transmission contention and issues a TXOP reservation request to the QAP in the time slot if the random number is lower than the upper limit. The QAP generates a reservation result. The QAP broadcasts the reservation result to the QSTA if more than one QSTA issued reservation requests in the same time slot. The QSTA selects a new time slot for data transmission contention and issues a new TXOP reservation request to the QAP in the new time slot if the previous reservation is not successful according to the reservation result.
