Ranging Middleware Design for Body Sensor Networks
نویسندگان
چکیده
In this paper, we propose a short ranging middleware built on WUSB (Wireless USB) over WBAN (Wireless Body Area Networks) hierarchical protocol for body sensor networks. The proposed middleware platform is composed of time-synchronization and optimal short ranging solution. The optimal ranging solution is proposed through comparison of experiment results from ToA (Time of Arrival), TDoA (Time Difference of Arrival), FDoA (Frequency Difference of Arrival) and AoA (Angle of Arrival) schemes. And it is executed at each body sensor node on the basis of WUSB over WBAN protocol. After time-synchronization is executed, a WBAN host calculates the location of a receiving sensor node by using the ranging solution. And the WBAN host interprets status and motion of the body-sensor objects.
