Recent technological advances in wireless communications and wireless sensor networks have enabled the
design of low-cost, intelligent, tiny, and lightweight medical sensor nodes that can be strategically placed on
human body, create a wireless body area network (WBAN) to monitor various physiological vital signs for a
long period of time and providing real-time feedback to the user and medical staff. WBANs promise to revolutionize health monitoring. In this paper, medical sensors were used to collect physiological data from
patients and transmit it to Intelligent Personal digital Assistant (IPDA) using ZigBee/IEEE802.15.4 standard
and to medical server using 3G communications. We introduced priority scheduling and data compression
into the system to increase transmission rate of physiological critical signals which improve the bandwidth
utilization. It also extends the life time of hand-held personal server by reducing power consumption during
transmission.
