“…In heterogeneous wireless networks (HWNs), the multi-homed mobile terminals rank the network interfaces and select the best one or simultaneously use the various available network interfaces. To meet the always best connected requirements, studies on NIS have used different mathematical theories including utility function [4,5], cost function [6], Multiple Attribute Decision Making (MADM) [7,2,8,9], Markov chain [10,11,12,13], fuzzy logic [14,15], game theory [16,17], and belief functions theory [18].…”
