Exploiting Path Diversity to Enhance Aggregating Throughput for Multihomed Wireless Devices

Multi-homed wireless devices equipped with multiple network interfaces can transmit data over multiple access paths simultaneously for high-speed services. It is essential for data transmission to select suitable number of paths to use from all available paths. At real multihomed network, multiple paths are likely to overlap each other and share the same bottleneck, which will weaken path diversity drastically. Spurred by this observation, selection of multiple paths should consider path correlation to select multiple independent paths as much as possible. In this paper, we propose a multi-path selection scheme to avoid underlying shared bottleneck between topologically joint paths. The results demonstrate that our approach under different network conditions is more accurate than other selection schemes, even with burst background traffic(1).
