Algorithm 2 Message Evaluator Selection

Input:
$E v a l L i s t = {S u m L i s t_{1}, S u m L i s t_{2}, \dots, S u m L i s t_{n}}$ .
$V e h L i s t = {V e h i c l e_{1}, V e h i c l e_{2}, \dots, V e h i c l e_{m}}$ .
Output:
$E v a l u a t o r L i s t = {E v a l u a t o r L i s t_{1}, E v a l u a t o r L i s t_{2}, \dots, E v a l u a t o r L i s t_{n}}$ .
1:
for each $V e h i c l e_{i} \in V e h L i s t$ do
2:
Data processing by using Simhash algorithm;
3:
Calculate Hamming distance of $V e h i c l e_{i}$ and $E v a l L i s t$ ;
4:
if Hamming distance ( $V e h i c l e_{i}$ , $E v a l L i s t$ ) < ⊝ then
5:
Add $V e h i c l e_{i}$ to $E v a l u a t o r L i s t$ ;
6:
end if
7:
end for
8:
Return $E v a l u a t o r L i s t$ .
