A WLAN and Bluetooth Coexistence Mechanism for Health Monitoring System
Mu-Sheng Huang, S. Lee, S.-C. Park · 2009
The rise in world's aging population and escalating healthcare cost, necessitate directed research on new health monitoring paradigms. Upcoming health monitoring systems require the integration of heterogeneous wireless technologies, to achieve an 'anytime and anywhere' medical environment. The use of well established wireless technologies, such as Bluetooth and IEEE 802.11b Wireless LAN (WLAN) in medical environment, causes significant interference issue. However, existing coexistence mechanisms can not eradicate interference effectively and thus degrade the health monitoring system performances significantly. Therefore, an adaptive coexistence mechanism based on probabilistic packet scheduling with Quality-of-Service (QoS) provision is proposed in this paper.
