基于网关的ZigBee网络与Internet互联框架

摘要

针对如何将ZigBee网络与Internet紧密融合的问题,提出一种网关设计方案.介绍了工作在传输层的互联网关,在分析此网关不足的基础上,根据面向服务的网络中间件思想,提议网关的体系结构.包括服务注册、服务绑定、服务调用和取消服务4个模块,以实现为用户提供服务的透明性；同时,为了减少ZigBee网络节点占用的IP地址数目,服务调用模块中使用传输层网关的协议转换方式.该网关从网络协议和服务两个角度实现ZigBee网络和Internet网络的互联,通过分析和比较证明具有用户透明性、业务提供方便等特点.%A gateway design is presented for interconnection between ZigBee wireless sensor network and Internet. By analyzing the deficiency of the gateway working at the transport layer, a gateway framework is proposed. The method of providing services based on the thought of network middleware. There are four modules provide users with services by transparent way: service registration, service binding, service call and cancel the services. At the same time, in order to reduce the IP addresses for ZigBee network nodes, service call module uses the transport layer gateway protocol conversion method. This gateway connected WSN with Internet from two angles: network protocols and services. The analysis and comparison shows that the proposed gateway has the advantages of transparent to users and conveniently offering services.
