Radio access technology selection algorithm for heterogeneous wireless networks based on service type, user mobility and network load

A new algorithm for Radio Access Technology selection in heterogeneous wireless networks based on service type, user mobility and network load is presented in this paper. Performances of the proposed algorithm are evaluated by using Two-dimensional Markov chain. Performances of our algorithm are compared in regard to different single and two criteria RAT selection algorithms. A performance analysis shows that our RAT selection algorithm based on three criteria, shows better overall performances compared to single and dual criteria based RAT selection algorithms.
