分段故障的DSR协议

Question

我一直在试图找出为什么分割故障发生，但我不能与下面的代码可以有人帮助

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)   60       ; 
set val(nn)    20       ; 
set val(rp)    DSR      ; 
set val(x)    900      ; 
set val(y)    900      ; 
set val(stop)   800      ; 

set ns   [new Simulator] 
set tracefd  [open testDSR.tr w] 
set namtrace  [open testDSR.nam w] 
set windowVsTime2 [open win.tr w] 

$ns trace-all $tracefd 
$ns namtrace-all-wireless $namtrace $val(x) $val(y) 

set topo   [new Topography] 

$topo load_flatgrid $val(x) $val(y) 

create-god $val(nn) 

     $ns node-config -adhocRouting $val(rp) \ 
        -llType $val(ll) \ 
        -macType $val(mac) \ 
        -ifqType $val(ifq) \ 
        -ifqLen $val(ifqlen) \ 
        -antType $val(ant) \ 
        -propType $val(prop) \ 
        -phyType $val(netif) \ 
        -channelType $val(chan) \ 
        -topoInstance $topo \ 
        -agentTrace ON \ 
        -routerTrace ON \ 
        -macTrace OFF \ 
        -movementTrace ON 

    for {set i 0} {$i < $val(nn) } { incr i } { 
      set node_($i) [$ns node] 
    $node_($i) set X_ [ expr 10+round(rand()*480) ] 
     $node_($i) set Y_ [ expr 10+round(rand()*380) ] 
     $node_($i) set Z_ 0.0   
    }

$node_(4) color red

set tcp [new Agent/TCP/Newreno] 
$tcp set class_ 2 
$tcp set packetSize_ 1000 
set sink [new Agent/TCPSink] 
$ns attach-agent $node_(4) $tcp

$ns connect $tcp $sink 
set ftp [new Application/FTP]

proc plotWindow {tcpSource file} { 
global ns 
set time 0.01 
set now [$ns now] 
set cwnd [$tcpSource set cwnd_] 
puts $file "$now $cwnd" 
$ns at [expr $now+$time] "plotWindow $tcpSource $file" } 
$ns at 10.1 "plotWindow $tcp $windowVsTime2" 

# Define node initial position in nam 
for {set i 0} {$i < $val(nn)} { incr i } { 
    $ns initial_node_pos $node_($i) 30 
} 


# Telling nodes when the simulation ends 
for {set i 0} {$i < $val(nn) } { incr i } { 
    $ns at $val(stop) "$node_($i) reset"; 
} 


$ns at $val(stop) "$ns nam-end-wireless $val(stop)" 
$ns at $val(stop) "stop" 
$ns at 350.01 "puts \"end simulation\" ; $ns halt" 
proc stop {} { 
    global ns tracefd namtrace 
    $ns flush-trace 
    close $tracefd 
    close $namtrace 
    exit 0 
} 

$ns run 

我想知道需要什么样的修改，以避免分段错误错误。

感谢。

图：xgraph-12.x的被包括在NS-ALLINONE-2.35。也可用于Debian，Mint，Ubuntu。

DSR：实施例与延迟图（2）：聚类-moc_v1.tcl（一张xgraph窗口打开。）

DSR：实施例与损失图（3）：DSR-项目code_input。 tcl（六个xgraph窗口打开：移动顶部窗口观看“lost *，1 - 2 - 3”。）

DSR：将协议更改为DSR无线udp-1.tcl（三个xgraph窗口打开，用4倍损失曲线的第二个。四个延迟地块包括在顶部WINDO W的）

所有xgraph_ns2 - 文件 - tcl_05.2016 https://drive.google.com/file/d/0B7S255p3kFXNajQ5S1NuOHNTcUE/view?usp=sharing

此处可以正常工作，仿真结束时显示“分段故障”。所有的文件被创建OK：testDSR.nam 4.1MB，testDSR.tr 4.4MB，win.tr 220KB。

和：$ nam testDSR.nam→→确定（OK）NAM动画。

$ ns DSR_SUGMAR.tcl 
num_nodes is set 20
