Abstract
Smart biological control support systems that control medical devices based on sensed vital data in a body area network (BAN) have attracted attention. However, the current wireless communication standard IEEE 802.15.6ma does not take stable control of medical devices into consideration, and there is concern that the control system may become unstable. Therefore, in order to achieve stable operation of multiple control systems in a BAN, we propose an adaptive control MAC protocol that derives an upper bound of packet loss probability and based on it, operates dynamically. This protocol increases retransmission opportunities by allocating more timeslots to control systems with high packet error rate (PER), thereby improving the overall stability. In the simulation, the norm-squared mean of the state vector asymptotically approaches zero with adaptive control, resulting in improved stability.
