Wireless Routing Protocol PEGASIS Simulation

This document presents the simulation code for the PEGASIS wireless routing protocol, incorporating critical considerations for energy consumption and network lifetime. The implementation focuses on enhancing energy efficiency and extending node longevity through PEGASIS protocol mechanisms. The simulation employs chain-based data aggregation where nodes form a chain topology to reduce transmission distances, implementing greedy algorithm approaches for chain construction. Key features include energy modeling that calculates transmission/reception costs based on distance thresholds and residual energy tracking for dynamic chain reconfiguration. The code evaluates protocol performance under various energy consumption patterns and lifetime requirements, incorporating metrics like network coverage duration and energy depletion rates. Through this simulation, researchers can analyze PEGASIS's advantages in reducing energy expenditure by up to 50-70% compared to direct transmission, while examining limitations such as chain maintenance overhead. The implementation provides valuable insights for optimizing wireless network protocols and serves as a reference for future developments in energy-aware routing algorithms.
