@knudfl,
Yes, I already have the patch for Location Aided Routing (LAR) and Distance Routing Effect Algorithm for Mobility (DREAM) protocol. I have downloaded that patch from http://controls.ae.gatech.edu/claus/ns_lardream.html.
This patch has been developed by Claus Christmann at Georgia Tech. The authors of related paper only want that any published research from using their code include a reference to their IEEE INFOCOM 2002 paper: T. Camp, J. Boleng, B. Williams, L. Wilcox, and W. Navidi, Performance Comparison of Two Location Based Routing Protocols for Ad Hoc Networks, Proceedings of the IEEE INFOCOM, pp. 1678-1687, 2002.
One can request that code from Dr. Tracy Camp via their website http://toilers.mines.edu/Public/Code
I don't have new patch. I just edited the box.tcl file after successfully applying the patch to ns-2.32 so that simulation of LAR protocol is possible. Here is my box.tcl file of LAR protocol:
