| Abstract |
Due to the development of information and communication, there is a rising interest on WBAN(Wireless Body Area Network) that maintain and check the human being health. According to the application of different quality of service and a special mechanism for transferring medical data are required in WBAN environment. In this paper, we proposed the new formed superframe that has CSMA/CA based TDMA scheduling and CSMA/CA used IEEE 802.15.4 in order to process emergency data and on-demand data in WBAN environment. We estimated performance of the proposed MAC protocol by compared performance of other MAC protocols that are IEEE 802.15.4 MAC protocl and Z-MAC protocol has contention access period based TDMA scheduling. |
