基于802.15.4无线网络与以太网帧结构转换

对比当前的无线传感器网络的主要特点,设计了一种新型的网络。提出了将监测区域再分区的设想,同时对同一监测区域的不同类型的节点和相同类型的不同节点进行了区分识别。提出了类似网桥功能的Sink节点模型,设计了Sink节点的帧结构转换流程。针对目前IEEE802.15.4 16位短地址格式没有统一规范的情况,提出了基于节点区分的短地址格式设置,使得用户能够更方便的管理传感器节点。

Framestructure Transformation of Wireless Sensor Network and Ether Network

The characteristics of current main wireless sensor network is analyzed in this paper.By putting forward the idea of partitioning the monitoring area and making distingashment of the node in different types and the node in the same type,a new kind of network is designed,thus enabling the users to manage the wireless sensor network more effectively.In addition,a new kind of Sink node mode,like a network bridge,is also proposed,and the frame structure conversion process of the sink node is designed.A new kind of short-address format based on distinguishment of the sensor node is defined in view that the IEEE802.15.4 16bits short-address format has no unified specification.
