MATLAB Simulation Code for LEACH Protocol with Detailed Annotations and Implementation Insights

This MATLAB simulation code implements the LEACH (Low Energy Adaptive Clustering Hierarchy) protocol with detailed inline comments for enhanced readability and understanding. LEACH is an energy-efficient adaptive clustering hierarchy protocol specifically designed for wireless sensor networks (WSNs). The protocol extends network lifetime by dynamically organizing sensor nodes into multiple clusters and rotating cluster head responsibilities to distribute energy consumption evenly across the network. The simulation code provides a complete implementation of the LEACH protocol's core mechanisms, including: - Cluster formation algorithms using probabilistic threshold calculations - Dynamic cluster head selection based on residual energy levels - Energy consumption modeling for transmission, reception, and data aggregation - Round-based operation with periodic cluster reconfiguration Key functions in the code include energy initialization, cluster head election using random probability comparisons, cluster formation through advertisement messages, and TDMA schedule creation for intra-cluster communication. The implementation carefully models the two-phase operation (setup phase and steady-state phase) characteristic of LEACH protocols. The comprehensive comments explain each code section's functionality, parameter configurations, and algorithmic logic, enabling researchers and developers to easily understand the protocol's operation and modify the code for specific research requirements. This simulation serves as an excellent educational resource for studying energy-efficient routing protocols in wireless sensor networks and provides a foundation for further protocol enhancements and performance analysis. We hope this well-documented code facilitates your learning process and assists in your research and application of the LEACH protocol in wireless sensor network simulations.
