Many mobile cloud services require the end-to-end reliable data
transfer, TCP, across the two systems. There is a split-TCP proxy at the
edge of the wireless network cloud. The split-TCP proxy is the split
point for TCP flows. Such split-TCP proxy has been widely used in
cloud computing [27] and traditional cellular networks [39]. In the
context of cloud computing, split-TCP is also a popular scheme to
provide reliable data transfer for cloud services. The client sets up
a TCP connection to the nearby split-TCP proxy, then the split-TCP
proxy sustains a persistent TCP connection to the data center with
