The Dynamic Source Routing protocol (DSR) is a simple and efficient
routing protocol designed specifically for use in multi-hop wireless
ad hoc networks of mobile nodes. DSR allows the network to be
completely self-organizing and self-configuring, without the need for
any existing network infrastructure or administration. The protocol
is composed of the two main mechanisms of "Route Discovery" and
"Route Maintenance", which work together to allow nodes to discover
and maintain routes to arbitrary destinations in the ad hoc network.
All aspects of the protocol operate entirely on demand, allowing
the routing packet overhead of DSR to scale automatically to only
what is needed to react to changes in the routes currently in use. The
protocol allows multiple routes to any destination and allows each
sender to select and control the routes used in routing its packets,
for example, for use in load balancing or for increased robustness.
Other advantages of the DSR protocol include easily guaranteed
loop-free routing, operation in networks containing unidirectional
links, use of only "soft state" in routing, and very rapid recovery
when routes in the network change. The DSR protocol is designed
mainly for mobile ad hoc networks of up to about two hundred nodes
and is designed to work well even with very high rates of mobility.
This document specifies the operation of the DSR protocol for routing
unicast IPv4 packets. This memo defines an Experimental Protocol for the
Internet community.
This document is a product of the Mobile Ad-hoc Networks
Working Group of the IETF.
