ncrとエネルギー方程式に基づいて利己的なノードを検出しようとしています。利己的なノードを検出しましたが、それぞれncrとエネルギーに基づいています。そして、これら2つの条件を組み合わせるのに問題があります。 （ノードのncrが30未満でエネルギーがしきい値未満の場合は、利己的なノードとして分類されます。）
利己的なノードのエネルギー検出に基づくawkコード。
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;
}
利己的なノードを検出するためのNCRベースのawkコード。.shファイルを使用しました。

}

if(($33 == "REPLY") && ($5==node))
RepCounter++;
}
}
END {

done
echo "Total Number of Sefiish Nodes are:" $SelfishNodes
