The IEEE 802.15.6 standard for wireless body area network (WBAN) includes a slotted Aloha based protocol as an option for contention based medium access control. This protocol is different from the long studied classical version in that it has inherent considerations for certain priorities of users. An analytical model is presented for saturation throughput with this protocol in a network that is heterogeneous in user priorities. The model is validated against simulation.
