We propose a new synchronous MAC protocol with QoS awareness named AQ-MAC. AQ-MAC adopts a receiver initiated manner and provides QoS service per packet following the priority imposed. When a node has an incoming packet with high priority,it immediately turns on the radio in order to wait for a transmission initiated by a receiver. Otherwise the node keeps the low priority packets in a queue and sends out in a burst until a high priority packet comes or after a timeout value. In addition, AQ-MAC utilizes a packet concatenation scheme to improve the energy efficiency by reducing control overhead. We have evaluated AQ-MAC in multiple scenarios using ns-2. The results show that AQ-MAC adapts well with different types of traffic as well as achieves good performances of energy efficiency and latency.
