	Title		: The Dynamic Source Routing Protocol for Mobile Ad Hoc 
                          Networks (DSR)

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 mechanisms of 'Route Discovery'
and 'Route Maintenance', which work together to allow nodes to
discover and maintain source routes to arbitrary destinations in the
ad hoc network.  The use of source routing allows packet routing
to be trivially loop-free, avoids the need for up-to-date routing
information in the intermediate nodes through which packets are
forwarded, and allows nodes forwarding or overhearing packets to
cache the routing information in them for their own future use.  All
aspects of the protocol operate entirely on-demand, allowing the
routing packet overhead of DSR to scale automatically to only that
needed to react to changes in the routes currently in use.  This
document specifies the operation of the DSR protocol for routing
unicast IP packets in multi-hop wireless ad hoc networks.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
