Lately, the range of WBSN (Wireless Body Snesor Networks) applicability has expanded due to the support of the advanced wireless technology in the ubiquitous environment. WBSN is a network where various kinds of bio signals of the body are measured and then are processed and transmitted to neighboring monitoring and personal portable devices near human body. Current IEEE 802.15.4 MAC Protocol based on the FIFO (First Input First Output) principle allocates the time slot according to the order of requesting time for each node. However, this process may result in the increase the packet delay and a rate of packet loss when more packets than the available time slot attempt to transmit at the same time. Hence, in order to mitigate this performance degradation, we analyzed four types of the different scheduling scheme for effective controlling between the packet delay and packet loss in the system. The proposed buffer control applies the maximum delay restriction to new and previous data packets simultaneously in order to reduce the rate of the packet loss very effectively. Simulation results show that the proposes scheme attains the much smaller packet delay for the audio transmission and also reduces the packet loss for the audio and video packet transmission compared with the other schemes in view of availability of delayed packets as a effective data.
