By considering the benefits of using Wireless Sensor Network in Disaster Management, an appropriate structure for Wireless Sensor Network based on clustered and hierarchical models will be proposed. By applying different policies in each layer of proposed structure, energy consumption will be decreased. Furthermore, by studying the characteristics of the Wireless Sensor Network for Disaster Management, a new proper routing algorithm for using in the proposed Wireless Sensor Network will be presented. The proposed algorithm is based on some wildly used routing algorithm that adapted for the proposed structure for disaster management. By applying the proposed routing algorithm in the proposed structure energy consumption will be decreased and the time limitation for real-time data will be guaranteed. Increasing data transfer reliability is another benefit of proposed structure.
