In recent years, wireless sensor networks (WSNs) have garnered significant research attention due to their versatility in supporting a range of applications, including military surveillance, environmental monitoring, and infrastructure protection. WSNs offer low deployment costs, low energy consumption, and adaptability to complex geographical and climatic conditions. Particularly notable are their capabilities for self-organization, collaborative processing, and fault tolerance, which open up promising application potential across various fields. This paper focuses on the simulation and evaluation of data collection routing protocols in WSNs, specifically the Collection Tree Protocol (CTP) in mobile environments using the Contiki operating system and the Cooja simulator. Applications of data collection routing protocols in mobile environments include military surveillance and livestock monitoring. This study addresses efficiency issues such as energy savings and the maintenance of high data packet delivery rates under mobile network node conditions. These contributions provide practical benefits for both society and scientific advancement.
