Item An Optimized Protocol for Mobile Sink Position Dissemination in Wireless Sensor Networks(university of bordj bou arreridj, 2025) Yasmine HAMMACHE; Aya Hiba BERGHEULIn wireless sensor networks, the mobility of the sink improves data collection efficiency; however, it presents new issues as sensor nodes must be aware of the mobile sink’s current loca tion. The dissemination of this location via flooding results in increased energy consumption. This study presents a new protocol called An Optimized Protocol for Mobile Sink Position Dissemination in Wireless Sensor Networks (OPMPD), which is specifically designed for sce narios involving random movement of the sink and event-based data collection. The proposed solution seeks to address the aforementioned problem, wherein specific chosen nodes retain the sink’s latest position while decreasing energy consumption and controlling overhead. Using the NS-3 simulator, the performance of OPMPD is assessed, and the results, depicted through graphs, demonstrate its superiority over the comparison protocol known as VGB across various metrics achieving 63.25 % reduction in energy consumption, 47,52 % improvement in network lifetime, and 86.17 % reduction in control overhead.
