DSR (Dynamic Source Routing)

1. Source routing (full routing information)
2. On demand routing updates
3. Route Discovery and Maintainance
4. Bidirectional routing information updates by reversing the route request path.
5. Source initiates the Rreq (having Vs,Vd,Lsd).
6. Destination receives Rreq (may be more than one over the period of time), then sends a Rrep (a reverse mesaage) from the path which has shortest Lsd listing.
7. Intermediate nodes (Vi-Vj) also communicates bidirectionally to update their information. If fails then, Vi informs the Vj about Rerr and Vs initiates a new Rreq with a different route.
