A multidimensional Markov model for performance evaluation of network selection, handoff and traffic flow splitting algorithm in heterogeneous wireless networks

Next generation wireless networks will be heterogeneous. Multiple Radio Access Technologies (RATs) will be co-located in the same area. This paper focuses on how to get optimal performance of concurrent transmission in heterogeneous networks. Multidimensional Markov model is applied to evaluate the performance of the scheme which is proposed from a queue point. Furthermore, Minimum queuing delay based algorithm is presented and performance is analyzed in terms of average carried traffic and average delay. Numerical results illustrate our proposed framework is effective and the flow splitting transmission can obtain more performance gain in heterogeneous wireless networks.
