With the rapid development of the mobile computing and wireless network technology, the mobile telehealth system has been used more and more widely. An important issue of the telehealth system is that too many network traffics are generated while transferring data from the sensors to servers. To solve this problem, we propose a differential algorithm for reducing the network traffics of the telehealth system. The accuracy of sensors is often too high under some conditions and normally the captured data by sensors are little changed. Our algorithm provides an optimal tradeoff solution addressing both network traffics and data accuracy. The experimental results represent that the proposed approach can reduce network traffic effectively based on the acceptable data accuracy with choosing appropriate parameter.
