    摘要: In a virtual world, there are many entities moving and each has its own image and action. Due to the bandwidth limitation of the wireless environment, the transmission of image and actions among these entities is a problem. Before transmission, the action and image can be analyzed and converted into several kinds of commands. When the related entity receives the commands from other entities, it can generate the image and simulate the actions of other entities according to these commands. This paper proposes a transmission service to classify the transmitted commands into three kinds of transmission events. Three priority queues are used to transmit these data according to their priority. By this mechanism, some of the data, that are out of date and not to influence the virtual world , could be discarded and also kept the quality of the virtual world. To verify the advantage of this transmission service, an implemented prototype is based on the GSM short message system. The proposed prototype can also be applied in more advanced transmission system such as GPRS. Finally, the proposed prototype compares the time and data lose rate with the transmission mechanism of unique queue and three queues. The results show that the average wait time of the transmitted data packet and the transmission cost are reduced.
