A Hierarchical Optimization Approach for Prolonging Network Lifetime in Sensor Networks

Problem Definition

High energy consumption within Sensor Networks is a critical issue that significantly limits the lifespan and efficiency of these networks. The excessive energy usage not only leads to shortened network lifetimes but also hinders the overall functionality and service periods of the network. The key limitations and problems associated with high energy consumption include decreased network performance, limited data transmission capabilities, and increased maintenance costs. Additionally, the distance between cluster heads and sinks plays a crucial role in energy consumption, as it directly impacts the communication efficiency and power usage within the network. Therefore, there is a pressing need for an optimized approach that addresses these key pain points through efficient distribution, cluster selection, and reducing the distance between cluster head and sink.

By focusing on these aspects, the network's lifetime can be significantly enhanced, leading to longer service periods and improved overall functionality.
