Fuzzy logic based vertical handover algorithm between LTE and WLAN

In the future there is a need to provide seamless mobility to the heterogeneous wireless network user while on the move. To achieve this there is a need to design an efficient vertical handover mechanism. User preference and system condition should be taken into consideration for efficient vertical handover. As the 3GPP Long-term evolution or LTE is the upcoming WWAN technology, performing an efficient vertical handover between LTE and next generation wireless LAN will be the challenge for future research. In this paper a fuzzy based vertical handover algorithm NG-VDA is proposed to provide an efficient vertical handover between LTE and WLAN to the user on the basis of multiple parameters.
