摘要
根据目前无线传感网络无法直接接入以太网的现状,根据以太网交换机的工作原理提出了eWSN交换机(使用以太帧格式的WSN交换机)、EI-eWSN交换机(带以太网接口的eWSN交换机)以及逻辑网络节点的概念,设计并实现了基于TCP/IP协议的无线传感网络系统.系统将以太网地址应用于无线节点,并将数据封装成以太帧格式进行传输,实现了无线传感网络与以太网的无缝结合.
Because of the actuality that the wireless sensor network(WSN) can not be directly accessed into the Ethernet,this article proposes the conceptions of eWSN switch,EI-eWSN switch and logical net node according to the operation principle of Ethernet switch,and designs and achieves the WSN system based on the TCP/IP protocol.The Ethernet address is applied to the wireless node in this WSN system,and the data is encapsulated in Ethernet frame format for transmission,the seamless integration of WSN and Ethernet is realized.
