A New SCTP mobility scheme supporting vertical handover

Integration of heterogeneous networks constitutes the main concern of the next generation of mobile networks (4G). This integration is closely related to mobility management in the sense that a mobile user will move freely across mobile networks without connection disruption. Mobile IP based approaches suffers from drawbacks such as packet loss, high throughputs and handover latency. In this paper, we propose a new SCTP (stream control transmission protocol) mobility scheme supporting vertical handoff. The proposed scheme does not require any special infrastructure and presents less handoff latency compared to MIPv6 based approaches
