Abstract

Future generation networks are expected to be a combination of several types of access technologies that vary in their characteristics. Efficient handoff management techniques are required to enable end-users to seamlessly access these networks as they roam across different geographic locations. We describe recent protocols (application, transport, and network) such as Mobile IP, Session Initiation Protocol (SIP), and Stream Control Transmission Protocol (SCTP) that have been deployed to handle handoffs. We present an empirical performance evaluation of the three protocols using performance metrics such as handoff delay. We found that Mobile IP yields the highest handoff delay out of all the three mobility protocols. SIP and SCTP yield (33 %) and (55 %) lower handoff delays compared to Mobile IP.
