Wireless Body Area Network (WBAN), a network of sensor nodes placed in and around human body to monitor the patient’s health condition remotely in their day to day routine life without the person being in the hospital environment is the most envisioned area of WSN research. The main objective of WBAN is to deliver the patient’s vital signs during the emergency conditions with minimum time delay and maximum reliability. The emergency packets generated by sensor nodes in WBAN during such emergency situation should be provided prioritized service. This paper discusses a multiple Queuing technique to minimize the time delay of emergency packets. The emergency situation is phased based on the threshold value of the parameter being measured which results in high priority and low priority packets. Three types of packets generated by the nodes are prioritized in the following order, High Priority packets, Low priority packets and Normal packets. Simulation studies with varying number of nodes shows that nearly 90% of the low priority packets and 85% of the high priority packets are delivered within 30ms time delay with multiple queuing mechanism as compared to 60% (high priority packets) and 58% (low priority packets) with single queue.
