|Title:||Performance Metrics for IEEE 802.21 Media Independent Handover (MIH) Signaling|
|Published:||March 02, 2009|
|Abstract:||The IEEE 802.21 Media Independent Handover (MIH) working group is developing a set of mechanisms to facilitate migration of mobile users between access networks that use different link-layer technologies. Among these are mobility managers that create and process signaling messages to facilitate handovers. These messages are carried by the transport layer, and the IETF is developing an architecture to clarify the mechanisms that should be used. The proposed architectures employ both unreliable transport using User Datagram Protocol (UDP) and reliable stream transport using Transmission Control Protocol (TCP). In this paper we model the handover latency for the cases where UDP and TCP carry MIH signaling messages, and we discuss some of the design tradeoffs.|
