摘要
将来当计算机和通信设备遍布所有地方时,通信不仅是人—人和人—机之间,而且还包括机—机(M2M)之间的通信。在未来某一天,由机器产生的流量将大大超过人—机应用和人—人应用产生的流量。大量M2M应用需要用各种无线网络来支撑。本文旨在介绍迄今可用于机对机应用的各种无线网的特点和优劣,包括WiFi、蓝牙、ZigBee、无源RFID和802.15标准。
When computers and communication equipment are all over the place, communications will take place not only between people and between a person and a machine (computer), but also between a machine and another machine (M2M). The traffic generated from machines will substantially exceed the traffic from person-machine and person-person applications some day. So many M2M applications need to be supported by various wireless networks. The paper is aimed to present the features and their merits and demerits of various wireless networks for M2M applications, including WiFi, Bluetooth, ZigBee, passive RFID and IEEE 802.15 standards.
