摘要: 针对现有的异构无线传感器网络(WSN)体系结构中,不同的数据链路层缺乏通用架构的问题,提出在网络体系中增加“属性装配层”的概念。采用Ptolemy Ⅱ建模仿真平台,将属性装备层与数据链路层分别建模,首先采用属性装备层中的属性工厂模块分类各种通信协议原型,封装上层应用程序;然后采用装配工厂模块生产数据包头,分发于不同的网络;最后形成自适应的无线传感器网络体系。该体系融合了异构网络数据链路层,兼容了现有的平台、通信协议和网络机制,适用于未来的通信协议和机制。实验结果证明,基于该体系的通信系统内存占用和时间开销相对较小,具有自适应能力。

Abstract: In the existing heterogeneous Wireless Sensor Network (WSN) architecture, various data link layers lack a common structure. To solve this problem, the concept of attribute assembly layer was proposed. Based on the modeling and simulation platform of Ptolemy Ⅱ, the authors modeled the attribute assembly layer and the data link layer respectively, and then put forward an adaptive architecture for WSN. In the attribute assembly layer, the attribute factory was designed to classify various prototypes of communication protocols and encapsulate upper applications, while the assembly factory was designed to generate packet headers and distribute packets to different networks. This architecture unifies the data link layers for heterogeneous networks, and it is well compatible with the existing platforms, communication protocols and network mechanisms. What's more, it can be applied to potential communication protocols and mechanisms. The experimental results show that the communication systems based on this architecture have low memory occupation and time cost, and also have good adaptive capacity.
