Selfish node Detection Based on Fuzzy Logic and Harris Hawks Optimization Algorithm in IoT Networks

Table 2

Output fuzzy sets rang-reputation rate of each node.

Symbol	Description
Very very high (VVH)	Having maximum reputation (100% cooperative node)
Very high (VH)	Having above reputation (100% cooperative node)
High (H)	Having high reputation (100% cooperative node)
Medium (M)	Having average reputation (maybe cooperative node, need to be checked)
Low (L)	Having low reputation (having selfish behavior)
Very low (VL)	Having very low reputation (having selfish behavior)
Very very low (VVL)	Having little reputation (having selfish behavior)
