Wireless Sensor Networks have numerous applications, including natural disaster monitoring. In such applications, rapid transmission of data is crucial for timely event detection and response. While energy efficiency is a key research focus in WSNs, fast routing is even more critical in environmental monitoring scenarios, such as natural disaster surveillance. This paper proposes a partial upcasting data delivery method that uses hop counting from the sink node, without relying on location information. The effectiveness and reliability of this method are demonstrated through simulation experiments, showcasing its efficiency in meeting the demands of rapid data transmission in disaster monitoring.
