An Emergency Handling Scheme for Superframe-Structured MAC Protocols in WBAN
Wireless Body Area Networks (WBANs) provide a network communication service within the vicinity of a human body. Since, WBANs must provide both medical and Consumer Electronics (CE) services at the same time, the MAC protocol in WBANs must satisfy the requirements of each service, especially hwen considering the need for immediate and reliable data transmission during an emergency situation. In this paper, the authors propose an emergency handling scheme for WBAN MAC protocol. The proposed scheme can be applied to superframe-structured MAC protocols such as IEEE 802.15.4 and its extended versions which support dynamic Contention-Free Period (CFP) allocations. In addition, their scheme can be incorporated with working drafts for IEEE 802.15.6 standardization.
