Delay Analysis of GTS Bridging Between IEEE 802.15.4 and IEEE 802.11 Networks for Healthcare Applications

The authors consider interconnection of IEEE 802.15.4 beacon-enabled network cluster with IEEE 802.11b network. This scenario is important in healthcare applications where IEEE 802.15.4 nodes comprise patient's Body Area Network (BAN) and are involved in sensing some health-related data. BAN nodes have very short communication range in order to avoid harming patient's health and save energy. Sensed data needs to be transmitted to an access point in the ward room using wireless technology with higher transmission range and rate such as IEEE 802.11b. They model the interconnected network where IEEE 802.15.4-based BAN operates in Guaranteed Time Slot (GTS) mode, and IEEE 802.11b part of the bridge conveys GTS super-frame to the 802.11b access point.
