ncr과 에너지 방정식을 기반으로 이기적인 노드를 탐지하려고 합니다. 이기적인 노드를 감지했지만 각각 ncr과 에너지를 기반으로 합니다. 그리고 이 두 조건을 결합하는 데 문제가 있습니다. (노드의 ncr이 30 미만이고 에너지가 임계값 미만인 경우 이기적인 노드로 분류됩니다.)
이기적인 노드의 에너지 감지를 기반으로 한 awk 코드입니다.
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;
}
이기적인 노드를 탐지하기 위한 NCR 기반의 awk 코드입니다.. sh 파일을 사용했습니다.
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;

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