SenseNet

SenseNet is a graphical interface software designed for managing and monitoring network sensors. The program is intended to monitor connections between hosts within a specific static and immutable network through dedicated sensors.

Features

Core Features

• Create, modify and remove different types of sensors (5 different types)
• Search for sensors within the current connection using RegEx
• Data persistence through JSON save files
• Real-time monitoring and visualization of network metrics
• Multiple measurement visualization through dedicated graphs

Sensor Types

1. Bandwidth Sensor: Measures bandwidth usage (in Mbps) with maximum sensitivity of 1 Gbps per measurement
2. Error Sensor: Measures total errors (packet loss, collisions, etc.) with maximum sensitivity of 500 errors per measurement
3. Load Sensor: Shows connection occupancy (in %) relative to its maximum load capacity
4. Delay Sensor: Displays response time (in ms) with measurements up to 1000 ms
5. Jitter Sensor: Measures connection stability variations (in ms) with maximum sensitivity of 50 ms per measurement

File Operations

• Save: Overwrites the existing JSON file if previously exported/saved
• Export JSON: Saves configurations to a JSON file with custom path and filename
• Import JSON: Loads previously saved sensor configurations (JSON format only)

Keyboard Shortcuts

• CTRL+S (CMD+S on MacOS): Save
• CTRL+E (CMD+E on MacOS): Export JSON
• CTRL+I (CMD+I on MacOS): Import JSON
• CTRL+N (CMD+N on MacOS): Add new sensor

Technical Details

Data Persistence

• Configurations are saved in JSON format
• Each saved element contains:
  • Connection name
  • Associated sensors (ID and name)
• Invalid configurations or mismatched sensor types are ignored during import

Core Components

• Abstract classes for Sensors and Packets
• Host and Connection classes identified by name
• Implementation of non-trivial polymorphism through Visitor Design Pattern
• MVC architecture

Compilation Instructions (Ubuntu)

In the directory containing SenseNetCPPro.pro, execute:

qmake SenseNetCPPro.pro && make && ./SenseNetCPPro

Design Patterns

• Visitor Pattern for sensor type validation and graph simulation
• MVC architecture for separation of concerns

Requirements

• Qt Framework
• C++ compiler
• JSON support

Notes

• Only one sensor of each type can be added per connection
• Sensor IDs are unique and immutable
• Sensor names can be modified through the GUI
• Host and connection names are defined within the program and cannot be modified
