1. DSR: Dynamic Source Routing
Stands for: Dynamic Source Routing
Overview: Dynamic Source Routing (DSR) is a protocol used in mobile ad hoc networks (MANETs) that enables data to be sent between nodes using dynamically discovered routes. It is designed to work in environments where network topology frequently changes due to node mobility.
Key Components
- Route Discovery: When a node wants to send a packet, it initiates a route discovery process to find a path to the destination.
- Route Maintenance: Ensures that routes remain valid while data is being transmitted, detecting and repairing broken routes.
- Source Routing: The entire route to the destination is included in the packet header, which helps intermediate nodes forward the packet correctly.
Benefits
- Adaptability: Efficiently adapts to network topology changes, making it suitable for highly dynamic environments.
- On-Demand: Reduces overhead by discovering routes only when needed, rather than maintaining a constant routing table.
- Loop-Free: Ensures that packets are forwarded without routing loops, improving network reliability.
Applications
- Military Networks: Used in tactical networks where nodes (vehicles, soldiers) frequently move.
- Disaster Recovery: Provides communication in areas where traditional infrastructure is damaged or unavailable.
