Performance analysis of hybrid ARQ error-controlling scheme for UWB BAN

This paper presents hybrid type-II automatic repeat request (H-ARQ) for wireless wearable body area networks (BANs) based on ultra wideband (UWB) technology. It is shown that the improvement in performance in terms of throughput and error protection robustness is very significant. Thus, the proposed H-ARQ schemes can be employed and optimized to suit medical and non-medical applications. In existing researches [1], the delay by existence of the message of the other devices and its throughput efficiency has not been noted clearly. We show the effectiveness of the error control method from the definition of the amount of the message transmission delay.
