Enhanced media independent handover for vertical handover decision in MANET

Abstract

In heterogeneous mobile ad hoc network (MANET), seamless connectivity of a mobile node is the important challenge. Due to the mobility of the node, it may loss seamless connection. So, vertical handover techniques were presented to solve this issue. However, communication might get cancelled when handover takes place. This results in call drop and some other issues. So as to overcome these issues, an enhanced media independent handover/IEEE802.21 (EMIH) for vertical handover decision is presented in this paper. In this standard, adaptive neuro-fuzzy inference system (ANFIS) is included to select optimal network for vertical handover. Simulation results show that performance of the proposed approach outperforms that of the existing approach in terms of handover probability, drop, etc.
