Request-Based Polling Access: Investigation of Novel Wireless LAN MAC Scheme for Low-Latency E-Health Applications

For hospital e-health systems, a novel medium access control (MAC) scheme that achieves delay-sensitive healthcare traffic (DSHT) delivery in the uplink direction of wireless local area networks (WLANs) is proposed and investigated. By introducing a slotted request uploading period and informing hubs to upload their transmission requests orderly during the period, overhead cost associated with frequent transmitter/receiver transitions can be...
