Abstract: recently, different type of wireless networks are available for mobile devices and they easily integrate various network types such as 802.11, 802.16 and also 3G. Considering the variety among these networks, a mobile device should be able to do handover between these networks seamlessly. This is while the current standards such don’t provide the essential information to support handover in heterogeneous networks. In order to solve this problem, IEEE proposed a new standard named Media Independent Handover or IEEE 802.21. In this paper we will use this standard to improve handover performance of SCTP transport layer protocol with Dynamic Address Reconfiguration Extension. For this purpose, SCTP protocol will use event service of MIH protocol to detecting appropriate time for handover and also will apply command service of this protocol to decision making algorithm for selecting best alternative interface. Simulation results show that the method base on MIH is mor!
e efficient than SCTP protocol base on failover mechanism.
