网络 vanet 中的集群 + 使用 sumo+ns2 创建的文件移动性

Question

我想在一条道路上创建多个集群，其中包含在 ns2 中使用 somo 创建的移动文件。
文件mobility.tcl是相扑中的机动性。

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

    $node_($i) random-motion 0      ;# disable random motion
            $ns_ initial_node_pos $node_($i) 30

        for {set i 0} {$i < $val(nn) } {incr i} {
    set node_($i) [$ns_ node]   
    $node_($i) random-motion 0      ;# disable random motion
            $ns_ initial_node_pos $node_($i) 30
             }
     source mobility.tcl

    set udp0 [new Agent/UDP]
    $ns attach-agent $n(0) $udp0
    set cbr0 [new Application/Traffic/CBR]
    $cbr0 attach-agent $udp0
    set udp1 [new Agent/UDP]
    $ns attach-agent $n(1) $udp1
    $udp1 set class_ 1
    set cbr1 [new Application/Traffic/CBR]
    $cbr1 attach-agent $udp1
    set null0 [new Agent/Null]
    $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
    $ns at 1.0 "$cbr0 start"
    $ns at 1.1 "$cbr1 start"
    set tcp [new Agent/TCP]
   $tcp set class_ 2
   set sink [new Agent/TCPSink]
    $ns_ attach-agent $node_(0) $tcp
    $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*

您的代码几乎没问题，只是编辑了一些拼写错误。 Mac/802_11p 今天是 Mac/802_11Ext。除非你使用了 802_11p 的旧补丁并且构建失败。但我想这是一个错字。使用分层：节点必须分层创建。一个简单的"node creation"会导致

Address 32573 outside range of address field length 2048

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：我使用了具有 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 . Segmentation fault happens when the trace files are about 80MB, which is usable. Nam animation: OK.

编辑，6 月 5 日。分层：创建所需的分层节点：参见 ns-2.3x/tcl/{ex/{hier-rtg-10.tcl, hts100-0.tcl, test/hts1000.tcl} → → hts100-0.tcl，hts1000.tcl 被使用由 hier-rtg-100.tcl、hier-test-1000.tcl.
