To measure our success in meeting the design goals for GPSR, we
simulated the algorithm on a variety of static and mobile network
topologies. We focus mainly on the mobile simulation results in
this paper, as that part of the design space is more demanding of
a routing protocol—link additions and removals are far more frequent
under mobility. To compare the performance of GPSR with
prior work in wireless routing, we also simulate Johnson et al.’s
Dynamic Source Routing, DSR [12], [19], which has been shown
to offer higher packet delivery ratios and lower routing protocol
overhead than several other ad-hoc routing protocols [4].
