3) Multi-Path Network Access: Current mobile devices are always multi-homed, which means they are equipped with difference network interfaces, such as WiFi, 3G, LTE, WiMax, etc. Meanwhile, many heterogeneous wireless networks have overlapping coverage areas, which implies the possibility of multi-path network access. As has been discussed before, the information exchange between cloud and the client is various, which enables the potential improvement of system performance by scheduling different types of packages for multi-path network access. However, even though there have been a lot of studies in this area, practical solutions for multi-path wireless access are still needed
