The Next generation Wireless Networks(NGN) is envisage to integrate various heterogeneous wireless networks. The major challenging issue of the next generation wireless networks is to provide a quality of service(QOS) which is guaranteed and quality of experience(QOE).This specifies the QOS provided by the network & the QOS experienced by the user. The efficiency of the next generation wireless networks mainly depends upon the architecture and design of the future wireless networks. The most challenging task is to design various algorithms which provide best quality of service (QOS) and to efficiently support the mechanism of vertical handoff so as to provide seamless continuity of the calls even when the user is moving from one network to the other. This paper elucidates a comprehensive survey of the performance of various vertical handoff algorithms to decide the mechanism of selecting the best network among several available networks is discussed. A new algorithm Maximum Network Utility-Vertical Hand Off (MNU-VHO)algorithm is proposed. The investigation and results suggests that the proposed algorithm has better performance than other algorithms because it is more efficient, simple to implement and more dynamic (application oriented). © Research India Publications.
