bridge transmission method of medical sensor node in u-healthcare services
When monitoring vital sign, cables between medical sensors and monitoring system make a patient uncomfortable. Furthermore, it gets worse in case of a steady monitoring is needed. Recently researches, therefore, are actively underway to integrate a wireless sensor network into vital sign monitoring devices. However, the measured data from the sensor can't be transmitted if a patient moves out of the transmission range since the receiving and transmitting range of the measured date is limited within a specific range. In order to clear out this sort of problem, this research suggests the Bridge Transmission Method that can deliver data between nodes via other devices even if the medical sensor device went out of transmission range for a gateway. Experiments have been carried out by materializing a bridge transmission module on sensor nodes to verify effectiveness of our suggesting transmission method, and ten experiments having transmitted 1,000 packets by case showed 98.4\% of success in receiving
