This project demonstrates the prototyping of a routing algorithm in the NS-3 network simulator. It focuses on modifying the OLSR (Optimized Link State Routing) protocol, which traditionally uses hop count based on Dijkstra's algorithm for route calculation, to a new version that uses Signal-to-Noise Ratio (SNR) values as the routing metric.
The goal is to improve network performance by making routing decisions that reflect link quality, rather than just the number of hops. This leads to better metrics such as bandwidth utilization, packet delivery ratio, and reduced packet drops.
- Original Algorithm: OLSR with hop-count metric (Dijkstra-based shortest path).
- Modified Algorithm: OLSR with SNR-based metric for route selection.
- Benefits:
- Improved network throughput and stability
- Reduced packet drops in noisy or lossy environments
- Smarter route selection based on link quality rather than just distance
