Wireless Sensor and Actor Networks (WSANs) are increasingly being used as powerful and accurate tools for supervision and control of physical environments subject to emergency situations. In a fire condition, for instance, the sensor and actor network status can change dramatically. This paper presents a novel routing protocol that is aware of these changes and adjusts the routes accordingly, aiming to keep the Quality of Service required by the application. Route selection for different types of packets is performed considering QoS parameters such as latency, delivery rate and packet loss rate. Our protocol is also energy-aware and fault tolerant. Performance evaluation results show that our protocol outperforms other existing QoS-aware protocols, providing selective traffic with lower end-to-end latency, packet loss, and control packet overhead, besides network energy balancing and fault tolerance.
