我正在尝试根据 ncr 和能量方程来检测自私节点。我已经检测了自私节点，但分别基于 ncr 和能量。并且我在结合这两个条件时遇到了问题（如果节点的 ncr 小于小于30且其能量小于阈值，则归类为自私节点）
这是基于能量检测自私节点的 awk 代码。
BEGIN {
n=38
SelfishCounter=0;
Normalcounter=0;
}
{
# Trace line format: energy
event = $1
time = $2
if (event == "r" || event == "d" || event == "s"|| event == "f") {
node_id = $3
energy=$14
}
if (event=="N"){
node_id = $5
energy=$7
}
# Store remaining energy
finalenergy[node_id]=energy
}
END {
# finalenergy for each node
for (i in finalenergy) {
finalenergy[i]
totalenergy = 0
for (i = 0; i <= n; i = i + 1)
totalenergy += finalenergy[i]
}
###compute average energy
threshold=totalenergy/n
####output
for (i=0; i<n; i++) {
if(threshold >finalenergy[i]){
SelfishCounter++; }
else if(threshold <finalenergy[i]){
Normalcounter++; }
}
printf "number of selfish nodes:%d \n", SelfishCounter;
printf "number of normal nodes:%d \n", Normalcounter;
}
这是基于 NCR 检测自私节点的 awk 代码..我使用了 sh 文件
BEGIN {
ReqCounter=0;
RepCounter=0;
NCRCounter=0;
Normalcounter=0;
max_node = 0;
}
{action=$1;
if(action == "s" || action == "r" || action == "f")
{
if(($33 == "REQUEST") && ($5==node))
ReqCounter++;
if(($33 == "REPLY") && ($5==node))
RepCounter++;
}
}
END {
NCR= ((ReqCounter-(ReqCounter-RepCounter))/ReqCounter)*100;
if(NCR <= "30"){
NCRCounter++;
printf "SELFISH\n"; }
else{
Normalcounter++;
printf "NORMAL\n";}
# printf "The Node number is:%d \n", node;
# printf "The NCRis:%d \n", NCR;
#printf "REQUEST Count:%d \n", ReqCounter;
#printf "REPLY Count:%d \n", RepCounter;
}
#!/bin/sh
i=0
SelfishNodes=0
NormalNodes=0
while [ $i -lt 38 ]
do
value=$(awk -v node=$i -f NCR.awk DSR.tr)
echo "Node" $i "is" $value
i=`expr $i + 1`
if [ "$value" = "SELFISH" ]
then
SelfishNodes=` expr $SelfishNodes + 1`
else
NormalNodes=`expr $NormalNodes + 1`
fi
done
echo "Total Number of Sefiish Nodes are:" $SelfishNodes
echo "Totl Number of Normal Nodes are:"$NormalNodes
当我将上面显示的两个 awk 文件混合在一起时
BEGIN {
n=38
SelfishCounter=0;
Normalcounter=0;
ReqCounter=0;
RepCounter=0;
}
{
# Trace line format: energy
event = $1
time = $2
if (event == "r" || event == "d" || event == "s"|| event == "f") {
node_id = $3
energy=$14
if(($33 == "REQUEST") && ($5 == node))
ReqCounter++;
if(($33 == "REPLY") && ($5 == node))
RepCounter++;
}
if (event=="N"){
node_id = $5
energy=$7
}
# Store remaining energy
finalenergy[node_id]=energy
}
END {
NCR= ((ReqCounter-(ReqCounter-RepCounter))/ReqCounter)*100;
# finalenergy for each node
for (i in finalenergy) {
finalenergy[i]
totalenergy = 0
for (i = 0; i <= n; i = i + 1)
totalenergy += finalenergy[i]
}
###compute average energy
threshold=totalenergy/n
####output
if((threshold >finalenergy[i]) || (NCR <= 30)){
SelfishCounter++;
printf "SELFISH\n"; }
else{
Normalcounter++;
printf "NORMAL\n";}
}
}
}
#!/bin/sh
i=0
SelfishNodes=0
NormalNodes=0
while [ $i -lt 38 ]
do
value=$(awk -v node=$i -f energy-ncr.awk DSR.tr)
echo "Node" $i "is" $value
i=`expr $i + 1`
if [ "$value" = "SELFISH" ]
then
SelfishNodes=` expr $SelfishNodes + 1`
else
NormalNodes=`expr $NormalNodes + 1`
fi
done
echo "Total Number of Sefiish Nodes are:" $SelfishNodes
echo "Totl Number of Normal Nodes are:"$NormalNodes
出现以下错误

Ed Morton 编辑：这里是 OPs 2 第一个 awk 脚本，格式如下，gawk -o-因此它们具有缩进等，使代码更容易理解：
脚本1：
BEGIN {
n = 38
SelfishCounter = 0
Normalcounter = 0
}

node_id = $3
energy = $14
}
if (event == "N") {
node_id = $5
energy = $7
}
# Store remaining energy
finalenergy[node_id] = energy
}
END {
# finalenergy for each node
for (i in finalenergy) {
finalenergy[i]
totalenergy = 0
for (i = 0; i <= n; i = i + 1) {
totalenergy += finalenergy[i]
}
}
###compute average energy
