An enhancement of transport layer approach to mobility support

Abstract

In this paper, we propose an approach to transport layer mobility support leveraging the SCTP extension dubbed dynamic address reconfiguration. Timing issues related to the end-to-end address management, and a novel error recovery mechanism associated with a handover are discussed. The error recovery time of proposed mechanism is analyzed and compared to that of the plain SCTP for handover cases. Finally, through a series of simulations, the performance of the proposed SCTP enhancements over plain IPv6 is compared with the MIPv6 and its variants (i.e., HMIPvG and FMIPv6) with TCP Reno on top of them. The simulation results present the performance gains of the pro-posed error recovery mechanism, which is possible within the context of transport layer mobility management. © Springer-Verlag Berlin Heidelberg 2005.
