Recently, due to the increase in social intertest for advanced wireless telecommunication techniques, activated ubiquitous environments and healthcare, the application range of WBSN has been consistently expanding. WBSN environment has objective of collecting various bio-signals created directly or indirectly from in and out of the body, connecting with external networks and monitoring the display tool. Various bio-signals created in WBSN environment have unpredictable rate of emergency data occurrence by its nature. Such emergency data should be transmitted with priority compared to other periodic signals for prompt handling according to the condition of the patient. MAC protocol proposed in this thesis is in form of TDMA based on competitive reserved allocation by time-slot in CSMA/CA environment. This MAC protocol classifies the types of bio-signals with each different characteristic and settles the priority by type and the minimum transmission delay time of data accordingly. Especially for transmission of emergency data, MAC protocol reduces the transmission delay of emergency data and packet loss by setting priority.
