The convergency of medical sensor device and wireless sensor network is under way in order to improve personal health device for comfortable mobility of user or patient. The bridge transmission method between wireless personal health devices based on ad-hoc network has energy consumption problem caused by redundant packets. To solve the problem, we introduced transmission protocol for energy-efficiency as considering types of medical sensors, topology of u-Health network, and power of sensors. We also implemented an application on sensor nodes like a personal health device, and then we knew that transmission protocol is working well by checking out the payload data in each packet. The energy efficiency is a highly significant issue in a wireless sensor network, as well as transmission issue. We also need to consider energy efficiency in a application depending on type of sensor.
