Question

我想在道路上创建多个群集，并在ns2中使用somo创建移动文件文件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

             }
     source mobility.tcl

    set udp0 [new Agent/UDP]

    $ns attach-agent $n(50) $null0
    set null1 [new Agent/Null]
    $ns attach-agent $n(80) $null1
    $ns connect $udp0 $null0
    $ns connect $udp1 $null1

    $ns at 1.1 "$cbr1 start"
    set tcp [new Agent/TCP]
   $tcp set class_ 2

    $ns_ connect $tcp $sink
    set ftp [new Application/FTP]
    $ftp attach-agent $tcp

     #

     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*

编辑错误时，您的代码几乎正常。 Mac/802_11p今天Mac/802_11Ext。除非您使用旧补丁802_11p并且构建失败。但我想这是一个错字。使用分层：必须创建分层的节点。一个简单的节点创建＆＃34;会导致

地址字段长度2048以外的32573地址

错别字：ns有两个定义，ns和ns_。

node有两个定义n和node_ .....很容易修复：

$ sed -i 's/ns/ns_/g' somiMadani.tcl && sed -i 's/ns__/ns_/g' somiMadani.tcl

$ sed -i 's/n(/node_(/g' somiMadani.tcl

模拟：我使用了一个包含40个节点的SUMO移动文件：mobmod-teatinos-M40A.tcl，来自http://neo.lcc.uma.es/staff/jamal/vanet/?q=node/11。当跟踪文件大约为80MB时可以使用分段错误。南动画：好的。编辑过的文件，somiMadani-vanet.tcl→→Dropbox→https://www.dropbox.com/s/sv7p4tqc6pk0oje/somiMadani-vanet.tcl?dl=0可读，somiMadani-vanet.tcl.txt https://www.dropbox.com/s/fy8valous07m5er/somiMadani-vanet.tcl.txt?dl=0

Edit，Jun 5. Hierarchical：创建所需的分层节点：请参阅ns-2.3x/tcl/{ex/{hier-rtg-10.tcl, hts100-0.tcl, test/hts1000.tcl}→→hts100-0.tcl，hts1000.tcl由由hier-rtg-100.tcl，hier-test-1000.tcl。

使用

新示例，您的代码+ hts100-0.tcl代码段＆＃34; n-hts120-0.tcl＆＃34;：Vanet_n-802.11p.tar.gz https://drive.google.com/file/d/0B7S255p3kFXNcVcwSXhPWGUycDA/view?usp=sharing

网络vanet +文件中的群集使用sumo + ns2进行移动性移动
