Flow Distribution Strategy in heterogeneous networks based on satisfaction

In this paper, a new solution named Flow Distribution Strategy (FDS) is proposed to distribute various service flows with different features over several networks simultaneously. FSD includes a network selection algorithm and an access control algorithm. The former one uses modified Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) with combining fuzzy logic with multiple attribute decision making (MAMD). The latter one utilizes the notion of satisfaction, ensuring that service with higher satisfaction has the priority to be transmitted. Simulations show that FDS significantly reduces terminal switching time, effectively improves the average satisfaction and resource efficiency.
