A new energy‐efficient beacon listening scheme with a medium access control protocol is proposed for periodic vital signal monitoring in a wireless body area network system. The conventional system receives every beacon frame to adjust the protocol context; however, the proposed scheme receives only the necessary beacon frames. As a result, power consumption decreases by reducing idle listening times. The simulation results demonstrate that the proposed scheme reduces power consumption of the beacon mode to almost that of the non‐beacon mode. Compared with the normal beacon mode, it reduces the power consumption by 25% when the traffic model is assumed to be electrocardiogram (ECG). This is suitable for devices monitoring periodic data such as an ECG application.
