This paper describes an adaptive service differentiation scheme for medical grade QoS over WLAN healthcare networks. EDCA of the IEEE 802.11e Standard is used to enhance the QoS, where traffic priorities are categorized according to their criticality. The proposed scheme involves varying the contention window (CW) adaptively to reflect network conditions. This scheme is evaluated using NS2 simulation, and its performance is compared with those obtained for conventional EDCA of IEEE 802.11e with and without medical grade prioritization for traffic. Comparison results show significant advantage for the new proposed scheme.
