[ns] errors in propagation model
Hi all ,
I am new to NS-2(im using ns-2.28 an ns.2.30).I am trying to include Ricean
propagation model
with the following steps:
1-Copy the two files under ns-src(prop-ricean.cc,prop-ricean.h) into my NS
source directory
2-edit Makefile.in in my NS source directory and i added the
mobile/prop_ricean.o \ to OBJ_CC
3-Run configure
4. make clean
5. make
but when I am trying to test the Ricean propagation model using the following
code I got the
following error:
num_nodes is set 10
invalid command name "Propagation/Ricean"
while executing
"Propagation/Ricean create _o13 "
invoked from within
"catch "$className create $o $args" msg"

[ns] until Now Error in Ricean model
Hi ; Ihave sent you an email before and i'm wating your reply to solve error in Ricean model and also i have attched output of my TCL program with this message. ihave did the following steps: 1-Copy the two files under ns-src(prop-ricean.cc,prop-ricean.h) into my NS source directory 2-edit Makefile.in in my NS source directory and i added the prop_ricean.o to the list of objects under OBJ_CC 3-Run configure 4. make clean 5. make but when i have used TCL script it does'nt work . many thanks ibrahim Ibrahim Khider Eltahir Khider Communication Software and Switch Technology Research Center Dept of Electronic and Information Systems Huazhong University of Science and Technology ,P.R.China-Wuhan-430074 Mobile: 0086-27-63452269 Home Tel: 0086-27-87540211 - Take the Internet to Go: Yahoo!Go puts the Internet in your pocket: mail, news, photos & more.

[ns] ns2-in celluler
Hi friends I would like to construct a simple network similar to cellular network. I need to define the cell areas , then set up some base stations, the base stations should be able to find whether a particular mobile node is present in its cell area, by sending a paging message and receiving an acknowledgement. Base stations should be able to communicate among them to search for the users in other cells. Can this be done using NS2.If you know please share with me how.
