Omnet Dsr Code

Omnet Dsr Code (Dynamic source routing) protocol is also a simple and efficient routing protocol. DSR omnet code allows network model completely to be self organizing and also self-configuring, without any predefined infrastructure.

Characteristics of DSR routing protocol:

• With the optimization available it’s also a good choice for an ad hoc network.
• Uses source routing.
• Provides loop-free routes.
• Supports unidirectional links and also asymmetric routes.
• DSR protocol method also used in manet projects.
• Route replay message also from another host process.

Advantages of DSR routing protocol:

• Guaranteed loop free routing
• Nodes can able also to store multiple paths to destination
• Support also for use in networks containing unidirectional links
• Use of only “soft state” routing
• Rapid discovery when routes also in network change etc.
