Comparison of LEACH Protocol and DEEC Protocol

This comparison examines the LEACH (Low-Energy Adaptive Clustering Hierarchy) and DEEC (Distributed Energy-Efficient Clustering) protocols, both implemented in MATLAB with functional, executable code. The MATLAB implementations feature key functions for cluster head selection, energy consumption modeling, and data transmission simulation. The LEACH protocol employs randomized rotation of cluster heads using a probability threshold function, while DEEC utilizes a more sophisticated energy-based selection algorithm that accounts for heterogeneous node energy levels. Evaluating the comparative advantages and disadvantages of these protocols is essential for understanding their performance characteristics and optimal application scenarios. The analysis focuses on critical performance metrics including energy consumption patterns, network lifetime optimization, and data transmission efficiency. The LEACH implementation demonstrates a homogeneous approach with periodic cluster reformation, whereas the DEEC code incorporates residual energy calculations for adaptive clustering in heterogeneous wireless sensor networks. Through this comparative study, researchers can make informed decisions when selecting protocols for specific system requirements, thereby enhancing overall system performance and operational efficiency. The MATLAB code includes simulation parameters for network density, initial energy allocation, and communication range adjustments to facilitate comprehensive performance testing.
