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.
