Periods Scheduling Under the HCCA Mode of IEEE 802.11e

To provide strong and reliable support for voice (VO) and video (VI) traffic in IEEE 802.11e networks, a novel scheme called multiple periods scheduling (MPS) is proposed in this paper. Because the original HCCA mode does not support VI traffic properly, a special treatment for VI traffic is introduced by MPS. According to the requirements of both VO and VI traffic, the service period for each stream is assigned by MPS individually. With the...
