Transmitting variable-bit-rate real-time data on the uplink of a polled wireless local area network requires careful scheduling to achieve satisfactory performance and capacity. This is a 'blind' scheduling problem, since the number and arrival times of packets at each remote station are not known by the scheduler. Embedded round robin (ERR) was recently proposed to address the problem of the high cost of polling idle stations. This paper presents an enhancement of ERR, least-recently-used-ERR, which outperforms the original ERR, especially when network load is high.
