A novel vertical handoff decision making algorithm across Heterogeneous Wireless Networks

Heterogeneous Wireless Networks communication is a combination of various heterogeneous networks. With their complementary characteristics, incorporation of these technologies in the same network in order to provide a full coverage to mobile users causes several challenges such as handover decision making and mobility management. A good handoff decision should avoid unnecessary handovers, which increase the computational network load. In this paper, we present a novel approach for Handover decision making in the context of heterogeneous wireless network. The aim of the proposed scheme is the selection of the most suitable radio access network for each application. Simulation results show that the proposed approach can guarantee QoS requirements and reduce the blocking probability of new and handoff calls.
