i am using GPSR_KeLiu_SUNY_Binghamton.tar packet to simulate the gpsr protocol.
after"ns wireless-gpsr.tcl", when "nam gpsr.nam", the nodes in the nam picture can NOT move.
i have taken much time in solving this pro. now I have no idea! please help me!!!
thx very much!
wireless-gpsr.tcl as followed ：（scenario file generated by setdest: gpsr-kk is no problem!）
