# Mobility Prediction Model |
|
|
|
A deep learning-based system for predicting mobility patterns and handover requirements in wireless networks using LSTM neural networks. |
|
|
|
## Overview |
|
|
|
This project implements a sophisticated mobility prediction model that uses historical mobility data to predict when a handover between network cells will be needed. The model leverages LSTM (Long Short-Term Memory) networks to capture temporal patterns in user mobility and network conditions. |
|
|
|
## Features |
|
|
|
- LSTM-based deep learning model for sequence prediction |
|
- Comprehensive feature engineering including: |
|
- Spatial features (x, y coordinates) |
|
- Temporal features (velocity, heading) |
|
- Network metrics (signal strength, SINR, network load, throughput) |
|
- Time-based cyclical features (hour of day, day of week) |
|
- Categorical features (pattern type, device type) |
|
- Advanced model architecture with: |
|
- Dual LSTM layers with dropout for regularization |
|
- Dense layers for final prediction |
|
- Binary classification output |
|
- Robust data preparation pipeline |
|
- Early stopping and learning rate reduction callbacks |
|
- Comprehensive model evaluation metrics |
|
|
|
## Model Architecture |
|
|
|
The model consists of: |
|
- Input LSTM layer (64 units) |
|
- Dropout layer (0.3) |
|
- Second LSTM layer (32 units) |
|
- Dropout layer (0.3) |
|
- Dense layer (32 units, ReLU activation) |
|
- Output layer (1 unit, Sigmoid activation) |
|
|
|
## Performance Metrics |
|
|
|
The model is evaluated using: |
|
- Accuracy |
|
- Precision |
|
- Recall |
|
- AUC (Area Under the Curve) |
|
|
|
## Data Requirements |
|
|
|
The model expects the following features: |
|
- Spatial data: x, y coordinates |
|
- Mobility metrics: velocity, heading |
|
- Network metrics: signal_strength, sinr, network_load, throughput_mbps |
|
- Temporal data: timestamp |
|
- Categorical data: pattern_type, device_type (optional) |
|
- Target variable: handover_needed |
|
|
|
## Usage |

|
data, |
|
sequence_length=20, |
|
prediction_horizon=5 |
|
) |
|
|
|
# Build and train the model |
|
model = build_mobility_prediction_model(input_shape=(X.shape[1], X.shape[2])) |
|
model.fit(X_train, y_train, validation_data=(X_val, y_val)) |
|
``` |
|
