BAT Optimization Algorithm for Prolonging Wireless Network Operational Lifetime via Clustering with Intermediate Nodes

Problem Definition

In Wireless Sensor Networks (WSN), the process of clustering involves the selection of Cluster Heads (CH) responsible for processing, aggregating, and transmitting data to the sink. However, this process is energy-intensive and can significantly drain the resources of the nodes. It is crucial to ensure secure and efficient data transmission from the nodes to the base station while selecting CHs that consume less energy. Various clustering protocols have been developed to improve the efficiency of CH selection and ultimately enhance the network lifespan. One recent approach introduces the use of Cost value (Cv) for CH selection, where a node with the minimum Cv at each energy level is elected as the CH.

The Cv is determined based on parameters such as the average distance between nodes (Davg), initial energy level (En) at each level, and the number of nodes (Mr). While this approach has shown promising results, there is still room for improvement by incorporating advanced techniques, such as optimization through soft computing, to enhance the traditional approach and develop optimal CH selection criteria.

Proposed Work

In WSN, the clustering process for CH selection is crucial as it consumes a significant amount of energy. Various clustering protocols have been introduced to select CH efficiently and enhance the network lifespan.

This approach can be improved further by incorporating soft computing techniques like optimization. The objective of this proposed work is to enhance the CH selection approach in WSN using the BAT algorithm, which mimics the echolocation features of microbats.

The BAT algorithm is chosen for its efficiency in balancing exploration and exploitation during the search process, providing quick convergence, simplicity, and flexibility.
