Reducing Transmission Losses in Body Area Networks Using Variable TDMA Scheduling

The authors consider a typical Body Area Network (BAN) setting in which sensor nodes send data to a common hub regularly on a TDMA basis, as defined by the emerging IEEE 802.15.6 BAN standard. They explore variable TDMA scheduling techniques that allow the order of transmissions within each TDMA round to be decided on the fly, rather than be fixed in advance. The approach is related to opportunistic scheduling used in other multiuser wireless systems, which aims to maximize the system throughput by allocating transmission opportunities to users with the 'Best' instantaneous channel.
