We propose a primary path switching scheme to provide a seamless handover for dual-homed mobile terminals. This scheme is suggested as an enhancement to the mSCTP protocol. With our scheme, a mobile terminal performs primary path switching before it becomes unavailable due to its primary path drop. The improvement of the scheme comes from considering the temporal velocity of the mobile terminal with...
The purpose of this paper is to demonstrate a reliable construction of wireless local area network (WLAN) and universal mobile telecommunications systems (UMTS) interoperating system. The proposed system shall provide high data rates alongside a significant coverage area. It is known that WLAN makes available high data rates within a very restricted coverage. On the other hand UMTS provides comparatively...
The mobile Stream Control Transmission Protocol (mSCTP) can be used to support IP handover. This paper proposes an extension of mSCTP with bicasting for vertical handover across heterogeneous wireless access networks, in which the data packets of mSCTP are bicast to the old and new IP addresses in the vertical handover region. From the ns-2 simulation results, it is shown that the proposed scheme...
This paper presents an implementation of seamless vertical handover between WLAN and CDMA2000 networks using the recently proposed protocol- mobile stream control transmission protocol (mSCTP). A testbed based on a Linux platform has been set up to test the handover performance. In experiments, the handover delay is measured when the mobile node moves into and away from a WLAN. The results show the...
