Vertical Handover Decision Modelling in Heterogeneous Wireless Network

In essence, handover refers to a function within cellular networks and related communication systems, where it involves the transition of active data or services from one channel to another. The identical form soft handover procedure can take place in both cellular networks and satellite communication systems to guarantee uninterrupted transmission of data or services. Handover management has been the topic of research for the past decade which is now more prominent issues due to the growth of generation in wireless communication standards. The current generation of wireless communication belongs to emerging wireless platform which are referred has heterogeneous networks. This heterogeneity exists in all aspect so communication stating from the access technologies used, frequency of operation, applications supported, operating systems, multimode handheld devices etc. This heterogeneity puts forth challenges in providing seamless connectivity to the user due to the complementary characteristics of the access technologies and networks used in overlay scenario. One ofthe prominent issues isproviding good mobility management isthe basis for seam less communication. To provide an on-disruptive communication the management has to be taken care more. As this work deals with heterogeneous networks, the issue of vertical handover is of prime importance in order to achieve service continuity. The handoff parameter is controlled by ANFIS Techniques. The entire distance is monitored by RSS parameter. On the basis of RSS parameters, Channel capacity, throughput & jitter parameter is calculated. The handoff via ANFIS performed better throughput & Jitter values. For 4G Base Station, 2100MHz, 2300MHz and 2500 MHz is calculated for previous technique is calculated at 1118 meter, 1169 meter and 1215 meters respectively.
