在無線模擬的Trace文件中的該字段：
-Nl string Network trace Level (AGT, RTR, MAC, etc.)
誰能解釋一下這三個縮寫和含義，最好能說明他們在Trace分析中的用法或例子。
謝謝。
AgentTraces are marked with AGT,
RouterTrace with RTR and
MacTrace with MAC.
AGT 表示 agent，也就是業(yè)務(wù)層
RTR 表示 route，也就是路由層
MAC 表示 mac， 也就是接入層
一些分析總結(jié)貼出來：
Trace文件含義解析：
1、僅僅打開-movementTrace ON
a.格式定義
**** Mobile Node Movement:
M %.5f %d (%.2f, %.2f, %.2f), (%.2f, %.2f), %.2f
double Time
int Address (Node ID?)
double X Coordinate
double Y Coordinate
double Z Coordinate
double Destination X Coordinate
double Destination Y Coordinate
double Movement Speed
**** Mobile Node Energy：
N -t %f -n %d -e %f
double Time
int Address (Node ID?)
double Energy
b.實際Trace記錄和分析
M 0.01000 0 (1.00, 1.00, 0.00), (300.00, 300.00), 150.00
M 0.01000 1 (399.00, 399.00, 0.00), (399.00, 399.00), 50.00
M 0.01000 2 (360.00, 300.00, 0.00), (360.00, 300.00), 50.00
N -t 1.000000 -n 1 -e 0.500000
N -t 1.000000 -n 1 -e 0.500000
N -t 1.000000 -n 2 -e 0.500000
M 3.50000 2 (360.00, 300.00, 0.00), (100.00, 100.00), 200.00
M 4.00000 1 (399.00, 399.00, 0.00), (1.00, 1.00), 200.00
對應(yīng)的NS語句為：
$ns_ at 0.01 "$node_(0) setdest 300.0 300.0 150.0"
$ns_ at 0.01 "$node_(1) setdest 399.0 399.0 50.0"
$ns_ at 0.01 "$node_(2) setdest 360.0 300.0 50.0"
$ns_ at 4.0 "$node_(1) setdest 1.0 1.0 200.0"
$ns_ at 3.5 "$node_(2) setdest 100.0 100.0 200.0"
能量初值為0.5j.
2、僅僅打開-agentTrace ON
a.格式定義
N: Node Property
I: IP Level Packet Information
H: Next Hop Information
M: MAC Level Packet Information
P: Packet Specific Information
Flag Type Value
s(r,d,f) s(r,d,f) r Send；r: Receive；d: Drop；f: Forward
-t double Time (* For Global Setting)
-Ni int Node ID
-Nx double Node X Coordinate
-Ny double Node Y Coordinate
-Nz double Node Z Coordinate
-Ne double Node Energy Level
-Nl string Network trace Level (AGT, RTR, MAC, etc.)
-Nw string Drop Reason
-Hs int Hop source node ID
-Hd int Hop destination Node ID, -1, -2
-Ma hexadecimal Duration
-Ms hexadecimal Source Ethernet Address
-Md hexadecimal Destination Ethernet Address
-Mt hexadecimal Ethernet Type
-P string Packet Type (arp, dsr, imep, tora, etc.)
-Pn string Packet Type (cbr, tcp)
必須要注意的是-Hd的值經(jīng)常為-1 or -2.
-1意味著該分組是廣播分組。
-2意味著該分組的目的節(jié)點還沒有被設(shè)置，在應(yīng)用代理層和路由代理層的交互中較常用。
Between (-Nl AGT) and routing (-Nl RTR) levels.
依據(jù)分組的類型，可能會有下述標志被使用：
CBR Trace
Flag Type Value
-Pi int Sequence Number
-Pf int Number Of Times Packet Was Forwarded
-Po int Optimal Number Of Forwards
IP Trace
Flag Type Value
-Is int.int Source Address And Port
-Id int.int Destination Address And Port
-It string Packet Type
-Il int Packet Size
-If int Flow ID
-Ii int Unique ID
-Iv int TTL Value
AODV Trace
Flag Type Value
-Pt hexadecimal Type
-Ph int Hop Count
-Pb int Broadcast ID
-Pd int Destination
-Pds int Destination Sequence Number
-Ps int Source
-Pss int Source Sequence Number
-Pl double Lifetime
-Pc string Operation (REQUEST, REPLY, ERROR, HELLO)
