A high-speed fixed network is not suitable for a distributed remote monitoring environment because it lacks mobility. Therefore, wireless communication is another choice for transmission. This paper proposes a transmission service to classify the transmitted data into three kinds of transmission events. Three priority queues are used to receive the corresponding events and transmit these data according to their priority. By using this mechanism, some data that are out of date and not influencing the monitoring environment, could be discarded. In this way, the cost of transmitting data for monitoring is reduced. This paper also proposes mechanisms to handle data ordering and encoding problems. To verify the advantage of this transmission service, an implemented prototype is proposed based on the GSM short message system. The proposed prototype also compared the time and data loss rate with the unique queue, three queues mechanisms. The results show that the average wait time of the transmitted data packet and the transmission cost are reduced.
