Research on Self-adaptive Wireless Sensor Network Communication Architecture Based on Ptolemy II

Abstract

For the existing heterogeneous wireless sensor network architectures, different data link layers lack a common structure. To solve the problem mentioned above, this paper has proposed the concept of attribute assembly layer, and based on the hierarchical heterogeneous modeling of Ptolemy II, an adaptive architecture for wireless sensor network has been put forward. Experimental results show that this architecture has a low memory occupation and time cost. It unifies the data link layers for heterogeneous networks, and it is well compatible with the existing platforms, communication protocols and network mechanisms. The proposed architecture has good adaptive capacity, and it can apply to potential communication protocols and mechanisms.
