A implanted sensor's error probability is more likely to external sensor's error probability by biological characteristic in WBAN. In this paper, we present method that external sensor transmits frame instead of doing implanted sensor's retransmission for improving lifetime of implanted sensors in WBAN. The proposed method, LI(Lifetime Increment) protocol is to add external sensor's id in transmission data frame of a implanted sensor. When the retransmission is required, external sensor that
