ABSTRACT
Wireless body sensor networks in healthcare system operate under incompatible conditions. All packet transmissions are served with their particular application dependent quality of service without endangering battery life time of body sensors. To fulfill the requirements, distributed queuing body area networks (DQBAN) protocol is introduced as an alternative enhancement to 802.15.4 MAC. It includes cross layer fuzzy rule scheduling algorithm and energy aware radio activation policies. The main idea is to amalgamate fuzzy logic system in each body sensors to deal with multiple cross layer input variables of dissimilar nature and independent manner. It guarantees low power consumption and suitable under coexisting scenarios. Simulation is carried out using NS2. DQBAN MAC model has shown to achieve higher reliability than other possible MAC implementation.
