A mobile handover mechanism based on fuzzy logic and MPTCP protocol under SDN architecture

In order to solve the problems in the process of vertical handover in heterogeneous wireless networks, We propose a mobile handover mechanism applied to the SDN(Software Defined Network) architecture on the basis of fuzzy logic algorithm combining with the Multi-path transmission control protocol(MPTCP) in this paper. This mechanism periodically acquires a number of network parameters and performs multi-angle evaluation of the network. The simulation results show that during the handooff process, the mobile device can always maintain the communication of one link and which will realize a true seamless handover. At the same time, due to the existence of the speed-adjusted vertical handover algorithm based on fuzzy logic(SVHAF), unnecessary handovers are effectively reduced, the ping-pong effect is avoided. Those also improve the quality of service(QoS) and user satisfaction.
