基于层次架构的WSN标签寻址技术研究

摘要

The traditional address-based addressing scheme cannot satisfy the addressing requirement of large-scale and business-centric wireless sensor networks (WSN). To solve this problem, a new hierarchical structure applicable to the large-scale heterogeneous WSN is proposed. Based on the structure, a label-based addressing (LBA) scheme is proposed as well. The proposed scheme different business types into the lables and marks the operated data. By creating a mapping between labels and node IP addresses, a user is able to query any business data through its label. The simulation demonstrates that LBA scheme is outperforms the traditional address-based and other content-based addressing schemes in terms of data request response time and packet delivery.%针对基于地址的寻址方式无法满足以业务为中心的大规模无线传感器网络(WSN)寻址要求的问题，提出了一种适合大规模异构WSN的层次架构和基于该架构的一种标签寻址( LBA)机制。LBA寻址机制将不同业务类型进行编码从而形成标签，对业务数据进行标记，通过建立标签与节点地址之间的映射关系，实现基于业务的寻址。仿真结果表明，LBA寻址机制在数据查询响应时间、报文递交率等方面都优于传统的基于地址和其他基于内容的寻址方式，更适合大规模分层WSN的应用。
