Dynamic Source Routing or DSR

Dynamic Source Routing or you may say DSR is normally or widely recognized as the part of Wireless Mesh Networks being their routing protocol. The similar protocol to this in-discussion routing protocol is recognized as AODV in which a route is formed on-demand whenever a route is requested by any transmitting computer. Source routing is normally used by this routing protocol instead of relying on the table known as routing table at each device known as intermediate device.

May refinements or you may say successive refinements to this in-discussion Dynamic Source Routing or you may say DSR have been made so far in which DSRFLOW is also included. Accumulating of each device’s address is normally required by the routes of determining source between destination, as well as source during discovery process of the route.

The information related to the accumulated path is normally cached by nodes that actually involved in processing the packets known as route discover packets. These packets are normally routed by the paths known as learned paths. Each device’s address is actually carried by every single routed packet just to accomplish or complete the source routing.

This technique may be resulted in high overhead for addresses or paths that normally are known as large addresses or long paths respectively in which IPv6 is also included. An option, known as flow id option, is normally defined optionally by the Dynamic Source Routing or you may say DSR protocol just in intention of avoiding using routing known as source routing.




This flow id option actually enables packets to be transmitted or you may say forwarded on the basis known as hop-by-hop basis.
