Resource Overview
LEACH (Low-Energy Adaptive Clustering Hierarchy) is an early classic protocol for wireless sensor networks that optimizes energy efficiency through adaptive hierarchical clustering. The protocol employs distributed cluster formation techniques and periodic cluster head rotation to evenly distribute energy consumption across network nodes. This repository provides multiple MATLAB implementations demonstrating cluster head election algorithms, energy consumption modeling, and network lifecycle simulations using probabilistic threshold calculations and round-based scheduling mechanisms.
Detailed Documentation
LEACH is a foundational protocol for wireless sensor networks designed to achieve low power consumption through adaptive hierarchical clustering techniques. The protocol enhances network longevity by periodically rotating cluster head roles, thereby distributing energy load evenly across all sensor nodes. The provided MATLAB codes demonstrate key algorithmic components including: 1) Stochastic cluster head election using threshold formulas (T(n)=P/(1-P*(r mod 1/P))), 2) Energy dissipation models for transmission and reception operations, and 3) Multi-round simulation frameworks with residual energy tracking. When implementing LEACH, consideration must be given to network topology parameters, node density distributions, and deployment scenarios to optimize protocol performance. The simulation scripts include visualization tools for analyzing cluster formation patterns and energy consumption trends across communication rounds.
