Wireless Networks: CMT using SCTP for consistent connectivity
As more and more devices are equipped with multiple network interfaces, the multi-homed technology is becoming an important technology that can provide more reliable connection against the network failure and higher data transmission rate. A transport layer protocol supporting multihoming allows an application to transmit data via multiple paths simultaneously (termed concurrent multi-path transfer or CMT for short). SCTP is an IETF-supported transport layer protocol with built-in multi-homing capability. CMT can transmit data over multiple paths to maximize the data transmission speed. One of the main concerns of CMT is the receiver buffer blocking issue, especially in multi-homed wireless networks (IEEE 802.11).Given recent advances in multiple radio nodes, multi channel radios, and multi-path routing we believe that we will see more multi-homed nodes in the wireless networks context. This motivates us to study the SCTP-based CMT over wireless networks. In this paper, we investigate the throughput of the applications using the SCTPbased CMT over IEEE 802.11 static multi-hop wireless networks with simulations. In this paper, we also explained why an application over CMT has higher throughput compared to the ideal AppStripe application or an application over a single SCTP association in the MWN context.
