Dynamic In wireless sensor networks (WSNs), sensor nodes located near a static sink often experience
higher traffic loads due to their role in forwarding data, which significantly reduces the network's overall lifetime. This issue is commonly referred to as the hotspot problem. The use of mobile sinks has been proposed as an effective strategy to alleviate this issue. While sink mobility offers many benefits, it introduces new challenges related to the dynamic network topology, making data transmission to the mobile sink more complex. Sensor nodes must frequently reconstruct their routes to track the mobile sink's latest location, which undermines the goal of energy conservation. We propose an enhanced dynamic route adjustment scheme using optimal path for mobile sink, designed to minimize the route reconstruction costs while maintaining near-optimal paths to the mobile sink’s current location. The network is partitioned into clusters of equal size and CH is designated for each cluster. Additionally, to manage the route readjustment
process efficiently, we establish a set of communication rules. This approach aims to extend network
lifetime by reducing the overhead associated with dynamic route adjustments.
