Abstract: Mobile Wireless Sensor Networks (MWSNs) are an important part of the Internet of Things (IoT), where many sensors are connected through wireless channels. However, there are challenges related to energy consumption, connectivity, scalability, and security in MWSNs. Adding mobility makes it even more challenging to find a good way to improve MWSN performance. This paper introduces a new routing protocol called "Triple Tier Cluster-Based Routing" (TTC-BR) that improves MWSN performance. It does this by dividing the network into virtual zones and using a triple-tier clustering approach. The virtual zones cover the entire network area using three levels: the main connectivity zone (MCZ), candidate cluster zone 1 (CCZ1), and candidate cluster zone 2 (CCZ2). The protocol selects the best sensor node to act as the Cluster Head (CH) for each zone.TTC-BR outperforms other routing protocols such as DDR, MCCA, LEACH-MEEC, and LEACH-M, and can improve network lifetime by 9% to 48%. Our study suggests that TTC-BR is an efficient solution to improve the performance of MWSNs, particularly for large networks and many sensors.
