Seamless mobility for WiFi-WiMAX heterogeneous networks using SCTP and DNS

Abstract

In this paper, a new seamless mobility for WiFi and WiMAX heterogeneous networks by the use of mobile SCTP and Domain Name Service (DNS) for location management is proposed. This mechanism will not only achieve seamless mobility, but also provide for energy conservation on unused network interfaces. This mechanism does not require change of infrastructure since DNS is part of every network and hence has an advantage over Mobile IP and SIP which introduce third party servers such as home and foreign agents and SIP server.
