In such converged systems, the seamless and efficient handoff between different access technologies (vertical handoff) is crucial and vestiges a challenging issue. The heterogeneous co-existence of access technologies with largely different characteristics results in handoff asymmetry that differs from the traditional intra-network handoff (horizontal handoff) predicament. In the case where one network is preferred, the vertical handoff decision should be carefully executed, based on the wireless channel state, network layer characteristics, as well as application requirements. In this paper, we study the performance of vertical handoff using the integration of 4G cellular and wireless local area networks as an illustration. We present an analytical framework to evaluate the converged system performance, which is validated by computer simulation. We sh...
