Abstract

This paper describes an adaptive service differentiation scheme for medical grade QoS over WLAN healthcare networks. The wireless transmission of medical applications over wireless networks needs special QoS requirements meanwhile, IEEE802.11 Standard does not fulfill the QoS requirement yet. Enhanced Distributed Channel Access (EDCA) of the IEEE 802.11e Standard is used to enhance the QoS, where traffic priorities are categorized according to their criticality. The simulation has been performed to deliver three traffics with different priorities. The proposed algorithm is evaluated using NS2 simulation. The simulation results shows that the medical access categorization and the contention window control mechanism significantly improve the performance of a medical network over IEEE 802.11E. Comparison results show significant advantage for the new proposed scheme.
