The mobile wireless environment can be challenging for multimedia applications, with poor performance and handover issues causing service degradation. In this paper, a modified version of the new IETF transport protocol, SCTP, is shown to improve the performance of a voice-like application in an environment where two wireless LAN's overlap. It does this by monitoring both networks and selecting the network with the better performance. This paper shows simulations of an SCTP handover scheme which selects the better path based on a moving average of end-to-end delay. The significant contribution of this work is to show the feasibility of a mobile transport protocol, based on SCTP, that can handover between networks and support multi-media type traffic.
