TrustyFeer: A Subjective Logic Trust Model for Smart City Peer-to-Peer Federated Clouds

Algorithm 3

Compute trust value.

(1) procedure ComputeTrust

(2) create matrix OF of opinion elements

(3) for each CSPs in the system do

(4) discount and then consensus opinions in OF

(5) end for

(6) for each position in matrix OF do

(7) if the believe of the opinion in OF is max then

(8) store the opinion with the max believe in OF′

(9) end if

(10) end for

(11) export the stored value in OF′ to the global trust matrix

(12) compute opinion expected values as trust values

(13) end procedure
