摘要：

Reliability is a critical design parameter in wireless body area networks (WBANs). In this study, the authors quantify the reliability of WBAN based on the network lifetime, and derive a general formula of the reliability in terms of the number of sensors and group characteristic parameter (GCP). Upper and lower bounds of the reliability are derived for an arbitrary WBAN. Based on the monotonicity property of reliability, an algorithm by using average GCP is presented to calculate the minimum and maximum number of sensors for a given network lifetime, and the optimal number of sensors for a given reliability. The performance of reliability is evaluated through numerical results.
