在无线模拟的Trace文件中的该字段: -Nl string Network trace Level (AGT, RTR, MAC, etc.) 谁能解释一下这三个缩写和含义,最好能说明他们在Trace分析中的用法或例子。 谢谢。
AgentTraces are marked with AGT,
RouterTrace with RTR and
MacTrace with MAC.
AGT 表示 agent,也就是业务层 RTR 表示 route,也就是路由层 MAC 表示 mac, 也就是接入层
一些分析总结贴出来:
Trace文件含义解析:
1、仅仅打开-movementTrace ON a.格式定义 **** 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.实际Trace记录和分析 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
对应的NS语句为: $ns_ at 0.01 "$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"
能量初值为0.5j.
2、仅仅打开-agentTrace ON a.格式定义 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)
必须要注意的是-Hd的值经常为-1 or -2. -1意味着该分组是广播分组。 -2意味着该分组的目的节点还没有被设置,在应用代理层和路由代理层的交互中较常用。 Between (-Nl AGT) and routing (-Nl RTR) levels. 依据分组的类型,可能会有下述标志被使用: 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)
ARP Trace Flag Type Value -Po string Request or Reply -Pms int Source MAC Address -Ps int Source Address -Pmd int Destination MAC Address -Pd int Destination Address
