Abstract

Recently, wireless body area networks (WBAN) have attracted attention. As an international standard of WBANs suitable for medical fields, IEEE802.15.6 has been established in February 2012. In this standard, it is possible to divide the quality of service (QoS) of handled data into 7 different user priorities. However, means for the concrete realization in accordance with these priorities is implementation-dependent in UWB-PHY. From this problem, we has employed Decomposable codes and Weldon's ARQ for the proposed scheme in order to adjust balance between error correcting capability of codes and the number of retransmission according to each medical QoS. We have showed that the proposed scheme has been able to improve BER and throughput performances satisfying each medical QoS by computer simulation.
