  Dynamic Source Routing (DSR) is an efficient on-demand routing protocol for
mobile ad-hoc networks (MANET). It depends on two main procedures: Route
Discovery and Route Maintenance. Route discovery is the procedure used at the
source of the packets to discover a route to the destination. Route Maintenance
is the procedure that discovers link failures and repairs them. Route caching
is the sub procedure serviceable to avoid the demand for discovering a route or
to reduce route discovery delay before every data packet is sent. The goal of
this paper is to evaluate the performance of DSR. Different performance
expressions are investigated including, delivery ratio, end to-end delay, and
throughput, depending on different cache sizes and different speeds. All of
that as a study to develop a new caching strategy as a future work.
