所有的东西都能够相互交谈会怎么样?如果小开关,手表,FedEx邮箱,运输用的货盘,铲车,电话能够相互交谈会怎么样?许多小型电子产品设备能够以无线方式进行通信,但没有几个能够联网。这种区别是非常关键的:通信通常由一个同步程序控制,而联网则为设备提供了一种通用的结构,在其中能够交换信息。Bluetooth和IRDA 2使用自建立网络来满足这种需求,但他们都建立在客户机/服务器模式上。 What if all things talk to each other? What happens if small switches, watches, FedEx mailboxes, shipping pallets, forklifts, and phones can talk to each other? Many small electronic devices communicate wirelessly, but Few can be networked. The difference is crucial: communications are usually controlled by a synchronization program, and networking provides a common structure for devices in which information can be exchanged. Bluetooth and IRDA 2 use self-establishing networks to meet this need, but they are all built on client / server models.
