Performance Evaluation of Concurrent Multipath Transfer Using SCTP Multihoming in Multihop Wireless Networks

A transport layer protocol supporting multihoming allows an application to transmit data via multiple paths simultaneously (termed concurrent multipath transfer, or CMT for short). SCTP is an IETF-supported transport layer protocol with built-in multihoming capability. Earlier work by Iyengar et. al.proposed a CMT protocol using SCTP multihoming for improving application throughput, which studied the performance of CMT over wired networks using ns-2 simulations. Given recent advances in multiple radio nodes, multichannel radios, and multipath routing we believe that we will see more multihomednodes in the wireless networks context. This motivates us to study theSCTP-based CMT over wireless networks. In this paper, we investigate the throughput of the applications using the SCTP-based CMT over IEEE 802.11 static multihop wireless networks with QualNet simulations.
