Most of wireless sensor networks (WSN) research topics consider how to save the energy of the sensor nodes. However, in some applications of WSN, such as in the monitoring of an earthquake or forest wildfire, transmitting emergency data packets to the sink node as soon as possible is much more important than saving power. In this paper, we propose a Priority-based Hybrid Protocol (PHP) WSN model to provide a feasible WSN architecture, which can save the energy of the sensor nodes in normal situation, but will transmit emergency data packets in an efficient manner to the sink node. The simulation analysis shows that PHP obtains superior performance during emergency condition.
