Abstract
The Vertical hand off (VHO) plays the key role in an integrated heterogeneous for mobility. The heterogeneous wireless network (HWN)consists od different kind of networks like 2nd Generation 2G, GSM to 4th Generation 4G Long term evolution LTE. The HWN aims to provide all kind of services like voice, data, web browsing, video streaming with interruption mobility across each tier of the network. An VHO scheme helps to achieve mobility for such HWNs. In this paper we considered the HWN as K-tier and the VHOS decision is analysed based on the best possible decision process of analytical and hierarchical process (AHP). The Saaty's 9 point decision method is applied considering the key parameters of signal to noise ratio(SINR), traffic cost, Bandwidth and in-order to avoid the ping pong effect the advanced hysteresis buffer time included during the decision process. The simulation of the proposed VHOS reflects the optimum results.
