Delay-Centric Handover in SCTP over WLAN
نویسندگان
چکیده
In the field of personal mobile communications, it has been suggested that SCTP could provide a solution to the problems encountered by the currently implemented TCP/Mobile IP scheme. By exploiting SCTP’s multihoming feature to connect to several separate wireless networks concurrently, allows a Mobile Node to choose which wireless path suits the particular needs of the user application it is running. However, there is one drawback to this scenario the current handover scheme implemented in SCTP is failure-centric in nature. This paper proposes an improved handover scheme for SCTP. This proposed scheme offers the benefit of performing handover based on measured path delays, thus it does not require a path failure for handover to occur. In some cases it can actually pre-empt the path failure, and handover before it occurs.

Delay-Centric Handover in SCTP
The introduction of the Stream Control Transmission Protocol (SCTP) has opened the possibility of a mobile aware transport protocol. The multihoming feature of SCTP negates the need for a solution such as Mobile IP and, as SCTP is a transport layer protocol, it adds no complexity to the network. Utilizing the handover procedure of SCTP, the large bandwidth of WLAN can be exploited whilst in the...
