Question

I am simulating Wireless Sensor Network Using NS2.35 and I get an error
ns: _o108malicious: invalid command name "_o108malicious" while executing "o108malicious" when i add $ns at 3.2 "[$node($id) set ragent_]malicious"this line i get this error. set val(chan) Channel/WirelessChannel set val(prop) Propagation/TwoRayGround set val(netif) Phy/WirelessPhy set val(mac) Mac/802_11 set val(ifq) Queue/DropTail/PriQueue set val(ll) LL set val(ant) Antenna/OmniAntenna set val(ifqlen) 150 set val(nn) 25 set val(rp) AODV set val(x) 800 set val(y) 500 set val(stop) 150

当“设置恶意”行$ns at 3.2 "[$node_($id) set ragent_]malicious" ...被编辑为$ns at 3.2 "[$node_($id) set ragent_] hacker"时......那么您的文件工作正常：

$ ns235-malicious mal-wsn.tcl
num_nodes is set 25

channel.cc:sendUp - Calc highestAntennaZ_ and distCST_
highestAntennaZ_ = 1.5,  distCST_ = 550.0
SORTING LISTS ...DONE!
ns: scheduler going backwards in time from 6.000000 to 0.000000.

创建文件aodv.nam 200.0kB，aodv.tr 184.0kB。 $ nam aodv.nam &：确定动画和通讯。 $ awk -f tess-Packets.awk aodv.tr：好的，输出文件“Packets-arrival-time.txt”有338行。
不太稳定。也可以用
结束模拟
SORTING LISTS ...DONE ! Direction for pkt-flow not specified; Sending pkt up the stack on default.

...... NAM打开OK。现在的文件是：aodv.nam 328.0kB，aodv.tr 308.0kB。

完美。结束SORTING LISTS ...DONE!。动画：完美。文件是aodv.nam 7.0 MB，aodv.tr 5.7 MB。
Direction for pkt-flow not specified; Sending pkt up the stack on default. check_pktRTS:Invalid MAC Control subtype

...结论：您必须多次运行该文件才能获得完美的结果。如果Ubuntu可以是10次。如果是基于rpm的操作系统，则为3 - 4次。
