DSRFLOW

From Wikipedia, the free encyclopedia

DSRFLOW, the Flow-State extensions to Dynamic Source Routing (DSR), are a set of extensions that provide all of the benefits of source routing, without most of the per-packet overhead that is associated with source routing. It works by allowing most packets to be sent without a source route header, thus substantially reducing overhead. Indeed, one of the disadvantages of DSR was that the longer the source route of the packet was, the bigger the packet header became. The technique used is called implicit source routing. Flow state extensions to DSR were first described in:

Yih-Chun Hu and David B. Johnson. Implicit Source Routes for On-Demand Ad Hoc Network Routing. Proceedings of the 2001 ACM International Symposium on Mobile Ad Hoc Networking & Computing (MobiHoc 2001), pp. 1-10, ACM, Long Beach, CA, October, 2001.

The implicit source routing mechanism is now included in the DSR Internet Draft.
