摘要
在综合分析各感知网络和以太网网络特点及其异构性的基础上,提出了分层的异构网络融合网关结构模型,设计了网间通信统一的数据包格式和全网统一的地址编码方式.具有多切换接口的Mesh终端,能够根据自动切换管理技术智能地接入不同网络.网关实现了基于802.11、802.15和802.3等协议的语音业务、视频图像业务以及数据传输业务在不同网络间的无障碍通信,网关的双向通信功能,使其连通的两端网络以对等方式通信,最终实现了井下全网互联互通.
It analyzed the characteristics and heterogeneity among the sensor networks and the Ethernet network,hierarchical convergent gateway structure model was proposed,and it designed unified data packet format and unified address coding method of the network.Mesh terminal with multiple switching interface,could intelligently access to different networks according to the automatic switching management technology.The gateway could communicate with each other barrier freely in the voice,video and data transmission application based on 802.11,802.15 and 802.3protocols,the two-way communication of the gateway made the peer to peer communication between networks,it realized the whole network interconnection,barrier free communication finally.
