Fuzzy Constraints Notification MAC Protocol in Wireless Body Area Neworks

The QoS requirement, prolong network lifetime and supporting different types of traffics produced by various sensors in Wireless Body Area Network (WBAN) are the prominent barriers for deploying the network. The stringent QoS requirement, energy efficiency and delivery of emergency data have become the prime objectives of the researchers. We propose fuzzy constraint notification medium access control (FBN-MAC) protocol for QoS-aware data transmission over WBAN with prolonged network life time. Our proposed FBN-MAC protocol modifies the super frame of IEEE 802.15.4 model with an intention to reduce the loss rate and delay of the emergency data without degrading the QoS of non-emergent data. The remarkable design of this protocol is that the non emergency data types SD and BD can be transmitted in GTS if there is no emergency data traffic. The proposed protocol is compared with existing protocols through the simulation carried out in Castalia 3.2. The simulation results reveal that FBN-MAC outperforms the existing counterparts.
