Abstract: An increase in the popularity and usage of
Multimode’s devices for ubiquitous network access creates thrust for
utilization of simultaneous network connections. Unfortunately, the standard
transport layer protocols used single homed congestion control mechanism for multipath
transmission. One major challenge in such multipath transmission is related to
the Receiver Buffer (RBuf) blocking that hinders higher aggregation ratio of
multiple paths. This study proposed Simultaneous Multipath Transmission (SMT)
scheme to avoid the RBuf blocking problem. Realistic simulation scenarios were
designed such as intermediate nodes, cross traffic, scalability or mix of them
to thoroughly analyses SMT performance. The results revealed that SMT has
overcome RBuf blocking with improvement in aggregate throughput up to 95.3 % of
the total bandwidth.
Keywords: Multipath transmission, RBuf blocking, out-of-sequence
arrival, throughput, congestion window.
