IEEE 802.15.6 WBAN Beaconing for Wireless USB Protocol Adaptation
In this paper, an IEEE 802.15.6 Wireless Body Area Networks (WBANs) medium access control protocol is developed to support a Wireless USB (WUSB) application as a Protocol Adaptation Layer (PAL). Even though users can avoid colliding packets using CSMA/CA, hazard of beacon collisions still remains in the WUSB over WBAN networks. Further, in order to solve beacon conflict problem, the authors introduce a Multi-Channel Beaconing (MCB) for avoidance of beacon collision. The proposed MCB can minimize the possibility of beacon collision by efficiently managing the multiple available channels in a hybrid manner combining proactive and reactive method.
