摘　　要：为实现L2认知无线网络与以太网的互联,提出一种网络互联架构。为实现L2认知无线多跳网络中无线节点的快速寻址,设计一种编址方法,其利用IP地址和组网地址表征该网络中的无线节点;在网关中设计一种地址映射方案,通过设置地址映射表解决传统无线多跳网络中因广播造成的严重网络冗余和开销问题;为验证网关系统的通信能力、对传感数据的采集和处理能力,构建“智慧园区微环境数据采集”平台对该系统的有效性进行了验证。A network interconnection architecture was given aiming to realize the interconnection between L2 cognitive wireless multi-hop network and Ethernet.To realize the fast addressing of wireless nodes in L2 cognitive wireless multi-hop networks,an addressing method was designed,in which IP addresses and network addresses were used to characterize wireless nodes in the network.An address mapping scheme was proposed in the gateway,which solved the problem of higher overhead caused by broadcasting by setting the address mapping table.A smart park microenvironment data collection platform was established to verify the ability of communication and data acquisition&processing of the gateway system.
