【问题描述】：
我想在道路上使用 ns2 中的 somo 创建的移动文件创建多个集群。
文件mobility.tcl 是相扑中的移动性。
我的代码如下：
set val(chan) Channel/WirelessChannel ;# channel type
set val(prop) Propagation/TwoRayGround ;# radio-propagation model
set val(netif1) Phy/WirelessPhy ;# network interface type
set val(netif2) Phy/WirelessPhy ;# network interface type
set val(mac) Mac/802_11p ;# MAC type
set val(ifq) Queue/DropTail/PriQueue ;# interface queue type
set val(ll) LL ;# link layer type
set val(ant) Antenna/OmniAntenna ;# antenna model
set val(ifqlen) 400 ;# max packet in ifq
set val(nn) 747 ;# number of mobilenodes
set val(rp) DSDV ;# routing protocol
set opt(x) 6162
set opt(y) 6029

set ns_ [new Simulator]
# set up for hierarchical routing
$ns_ node-config -addressType hierarchical
AddrParams set domain_num_ 10
lappend cluster_num 2 6 2 3 6 1 5 5 2 6

set tcp [new Agent/TCP]
$tcp set class_ 2

$ns_ attach-agent $node_(22) $sink
$ns_ connect $tcp $sink
set ftp [new Application/FTP]
$ftp attach-agent $tcp
$ns_ at 10.0 "$ftp start"
#
# Tell nodes when the simulation ends
#
for {set i 0} {$i < $val(nn) } {incr i} {
$ns_ at 500.0 "$node_($i) reset";
}
$ns_ at 500.0 "stop"
$ns_ at 1000.01 "puts \"NS EXITING...\" ; $ns_ halt"
proc stop {} {
global ns_ tracefd
$ns_ flush-trace
close $tracefd
}
puts "Starting Simulation..."
$ns_ run*
错误是：
madani@ubuntu:~/champ elysees$ ns paris2.tcl num_nodes is set 747 Error!! str2addr:Address 32573 outside range of address field length 2048*

1) 没有 SUMO 移动文件连接到您的文件。 2) 请查看经过测试的聚类示例drive.google.com/file/d/0B7S255p3kFXNM3g4d3FBRXFDM3c/… ... 3) 以及连接相扑文件的vanet 示例neo.lcc.uma.es/staff/jamal/vanet/?q=node/11 → urban-VANET-scenario-U1.tar.gz, urban-VANET-scenario-U2。 tar.gz, urban-VANET-scenario-U3.tar.gz
