Algorithm 1 Application request aggregation procedure.

INPUT: $\gamma ,A,I_{se}^c,{\alpha }_{new}$

OUTPUT: updating-flag, new $I_{se}^c$ if updating-flag = 1

Initialize: updating-flag = 0, $x\leftarrow \infty$

Repeat

x = aggregation($A,{\alpha }_{new})$

if $isNew(x,I_{se}^c)$ then

$I_{se}^c=x$;

updating-flag = 1

return updating-flag;

end if

return updating-flag;

UNTIL there is no new application request
