Abstract
Wireless Body Area Networks (WBANs) are expected to influence the traditional medical model by providing aged-care at home and health telemonitoring. In this work, we present a study of coexisting WBANs. Multi-WBANs coexist in a small area in many cases, which seriously affected the reliability of communication and the total throughput owing to the resource competition. In this paper, a joint carrier sensing threshold and power control mechanism is specially designed to meet demands of coexisting WBANs based on IEEE 802.15.4 standard using stochastic geometry. Due to the limited energy, the transmit power should be as small as possible based on the quality of received signal guaranteed. We derive the minimum transmit power under the different networks distribution and the carrier sense threshold.
