In the era of 3G mobile network (WCDMA,CDMA 2000, and TD-SCDMA) or 3.5G mobile (HSUPA, HSDPA, and HSPA+) network [4] due to the limited (low) data rate of network transmission and the large system delay (latency), the mobile augmented reality application can only be run in the mobile device following the download of the application from the backend server (e.g. Apple’s App Store). Figure 2 indicates the system configuration of SD-MAR in the 3G/3.5G mobile network. There are several drawbacks of executing MAR application program on the standalone SD including the limited computing power, storage volume, memory size and the big energy consumption. In the paper [1, 5] for mobile visual search in 3G networks, it points out that network latency remains the bottleneck for the system. For 3G connections, it also shows the average energy consumption in send image mode is almost 3 times as much as send feature mode. This is due to the slow transmission speed.
