摘　　要：针对无线传感网具有以数据为中心,以功能为重点,没有骨干结构等特点,文中提出了一种层次型无线传感网基于语义路由的数据转发算法,达到提高路由效率、延长网络生命周期的目的。该算法给出无线传感网中的语义定义和表达形式,利用语义框架构造数据分组,通过对数据分组中的语义同路由器中网络语义进行匹配,确定数据转发的方向。实验结果表明:网络中冗余数据少,节能性好,网络生存周期理想。该算法同时也可以为无线传感网的实时、交互操作研究提供一定基础。According to the characteristics of taking the data as the center,focusing on the functions,and be without the backbone structure in wireless sensor networks,a data-forwarding method based on semantic routing is proposed in order to improve the efficiency and in-crease the lifetime of the network. This algorithm presents the semantics definition and expression of wireless sensor network. Use these semantics structure to build data packets,match the semantics from the packets with the semantics of networks to determine the direction of data transferring. The experiments results show that the network has little redundant data,good saving function,ideal network lifetime. This could provide theoretic basis for researching on mutual and immediate operating.
