Proactive Handover Prediction in Vehicular Networks

Overview

This project investigates machine learning-based handover prediction in vehicular networks using hybrid deep learning models. We compare Graph Convolutional Networks combined with LSTM (GCN+LSTM) against an ensemble approach (GCN+LSTM+SVM) to predict optimal handover points in 5G mobile networks, minimizing latency and packet loss during vehicle mobility.

Technologies & Skills Demonstrated

  • Networking: 5G/LTE protocol stacks, handover mechanisms, mobility management
  • Machine Learning: Graph Neural Networks, LSTM, ensemble methods, PyTorch/TensorFlow
  • Simulation: Discrete event simulation, network modeling, performance analysis
  • Systems Integration: Bridging ML frameworks with C++ simulators, data pipeline design
  • Research Methodology: Comparative analysis, metrics definition, reproducible experiments

Technical Approach

Architecture

  • GCN+LSTM: Captures temporal-spatial dependencies using graph convolutions on network topology + sequential LSTM layers for temporal patterns
  • GCN+LSTM+SVM: Ensemble approach adding SVM for classification refinement, improving prediction accuracy

Integration & Simulation

  • Simu5G: 5G network simulator for realistic LTE/NR scenarios
  • OMNeT++: Discrete event simulator providing the core simulation framework
  • VEINS: Vehicular network integration layer
  • SUMO: Realistic traffic and mobility patterns for vehicles

Evaluation Metrics

  • Handover success rate
  • Handover latency (milliseconds)
  • Packet loss ratio during transitions
  • Prediction accuracy (precision, recall, F1-score)

Key Features

Deep Learning Integration: Seamless integration of PyTorch/TensorFlow models with Simu5G simulation engine
Realistic Scenarios: Vehicle mobility, path loss, interference, and multi-cell coverage variations
Ensemble Comparison: Systematic comparison of single-model vs. ensemble approaches
Comprehensive Analysis: Performance benchmarks across different vehicle speeds and traffic loads
