AB  - The heterogeneous nature of 3GPP-LTE network allows global roaming for a range of mobile access network by providing higher data rate and higher bandwidth services. To maintain seamless connectivity during frequent handover experienced by the roaming users and to provide seamless connectivity, an intelligent Vertical Handover Decision (VHD) algorithm is proposed which uses neural network based SMART (Simple Multi Attribute Rating Technique) algorithm for choosing the best network by calculating a set of criteria. It also aims at reducing delay by improving the Quality of Service (QoS) and also reduces unnecessary handovers by avoiding connection failure. To show the applicability the proposed scheme is applied to LTE (Long Term Evaluation) wireless network by integrating WiFi and WiMax networks. The simulation result shows that the proposed scheme reduces delay, number of packets lost, rate of failure and also improves the QoS by providing seamless connectivity when compared to SAW, TOPSIS and TOPSIS with knapsack algorithm existing in the literature.
