 abstract={In this paper a transport layer handover mechanism for  Voice over Internet Protocol (VoIP) using the Stream Control  Transmission Protocol (SCTP) is proposed. This handover  mechanism utilizes the multi-homing feature of SCTP to allow  connection to multiple wireless networks. Each available wireless  network is probed with simulated VoIP data to obtain network  performance metrics. Handover decisions are made based on the  Mean Opinion Score (MOS) calculated from the ITU-T E-Model for  voice quality assessment using the obtained measurements.  Implementation and simulations were carried out using the NS2  network simulator. The results show the MOS obtained using the  proposed handover mechanism on IEEE 802.11b WLAN access  points (APs) under varying load conditions. High correlation is  shown between the MOS from the proposed handover scheme and  the MOS experienced by a VoIP node present in the network. A  simulation showing an SCTP endpoint handover between AP’s is  presented.},
