新增 WiMAX Module (1/2) http://ndsl.csie.cgu.edu.tw/wimax_ns2.php http://ndsl.csie.cgu.edu.tw/wimax_ns2.php Download the latest ns-2 WiMAX module source code.latest ns-2 WiMAX module source code Unzip the ns-2 WiMAX module source code file which including three files : mac-802_16, common, and queue.ns-2 WiMAX module source code Put the "mac-802_16" directory into c:\cygwin\home\"your account"\ns-allinone-2.29\ns- 2.29\mac. Put the files which are in common and queue respectively into c:\cygwin\home\"your account"\ns- allinone-2.29\ns-2.29\common and c:\cygwin\home\"your account"\ns-allinone-2.29\ns- 2.29\queue. Modify the Makefile.

新增 WiMAX Module (2/2) Add that after the sentence mac/mac-802_3.o in the Makefile. mac/mac-802_16/packet-802_16.o \ mac/mac-802_16/timer-802_16.o \ mac/mac-802_16/mac-802_16.o \ mac/mac-802_16/traffic/UGS_traffic.o \ mac/mac-802_16/traffic/ertPS_traffic.o \ mac/mac-802_16/traffic/rtPS_traffic.o \ mac/mac-802_16/traffic/nrtPS_traffic.o \ mac/mac-802_16/traffic/BE_traffic.o \ To compile your files by excuting "make clean" then "make". An TCL example file is also available (TCL 5.75KB).TCL
