ZigBee Device Access Control and Reliable Data Transmission in ZigBee Based Health Monitoring System

One user's health monitoring system has a few ZigBee devices to measure one user's physiological data. Even if there are a lot of ZigBee devices nearby, the communication should be accepted between only one user's ZigBee devices. So, the access control should be implemented because there can be a lot of ZigBee devices nearby. There is an access control in MAC layer but we design and implement it in application layer to handle conveniently. The physiological data must not be lost but a wireless communication such as ZigBee can lose a data. So, this paper proposes the reliable data transmission not to lose a physiological data in ZigBee based health monitoring system.
