中文摘要	本发明涉及一种面向分簇无线传感器网络的两级自适应跳频方法,包括以下步骤:构建分簇无线传感器网络;基于上述分簇无线传感器网络的拓扑结构定义基于IEEE?802.15.4的超帧结构;基于原有IEEE?802.15.4的介质访问控制层信标帧格式,扩展信标帧载荷的内容;基于上述超帧结构以及扩展后的IEEE?802.15.4的介质访问控制层的信标帧,实现网络中节点的两级自适应跳频过程。本发明方法采用分簇无线传感器网络,扩大了网络规模,降低了维护和管理的难度,提高了系统的灵活性;设计了两级跳频方法,保证了对IEEE?802.15.4的兼容性和系统的可靠性;基于IEEE?802.15.4的信标帧载荷,在信道切换过程中不需要设计专门的帧用于广播信道分配结果,简化了网络设计,减少了用于控制的帧的数量,提高了网络吞吐量。

英文摘要	The invention relates to a clustering-wireless-sensor-network-orientated two-stage adaptive frequency-hopping method. The method comprises the following steps of: constructing the clustering wireless sensor network defining a super-frame structure based on institute of electrical and electronic engineer (IEEE) 802.15.4 according to the topological structure of the clustering wireless sensor network accessing a format of a beacon frame of a control layer based on a medium of the original IEEE 802.15.4, and extending a content of a beacon frame load and accessing the beacon frame of the control layer based on the super-frame structure and the extended medium of the IEEE 802.15.4 so as to realize a two-stage adaptive frequency-hopping process of a node in the network. By the clustering wireless sensor network, the network size is expanded, the difficulty in maintenance and management is lowered, and the system flexibility is improved as the two-stage frequency-hopping method is designed, the compatibility with the IEEE 802.15.4 and the system reliability are guaranteed and based on the beacon frame load of the IEEE 802.15.4, no special frame is not needed to be designed for a broadcast channel distribution result during a channel switching process, so that the network design is simplified, the number of the frames for controlling is reduced, and the network throughput is increased.
