QoE-Driven D2D Media Services Distribution Scheme in Cellular Networks

Algorithm 1

MSAUS scheme.

(01) Input:

(02) User U, media service M, Initial all SRC value

(03) Popularity function and Priority function

(04) Output:

(05) Optimal Media Service Adaptive Update Scheme

(06) Procedure MSAUS

(07) if (user i requests media service m)

(08)if (in the D2D transmission radius r user j)

(09);

(10)else

(11)User j provide the media service to user i;

(12)set and

(13)m replaces the minimum priority media in i

(14)if ()

(15)i share m to the other users when they meets
