This paper investigates the performance of cooperative receive diversity, for the wireless body area network (WBAN) radio channel, compliant with the IEEE 802.15.6 Standard, in the case of monitoring a sleeping person. Extensive WBAN measurements near the 2.4 GHz ISM band were used. Up to 7 dB and 20 improvement for two-hop communications with the use of relays are empirically demonstrated with respect to outage probability and outage duration, with 3-branch cooperative selection combining and 3-branch cooperative switch-and-examine combining.
