摘要: 目前对于无线传感器网络实时性与可靠性的研究大多通过IEEE 802.15.4标准MAC协议性能分析、协议优化或理论建模等手段,而没有关注IEEE 802.15.4标准超帧结构中竞争访问控制阶段(CAP)与非竞争访问控制阶段(CFP)两种访问阶段持续时间对网络实时性与可靠性的影响。通过建立状态机模型,设计并实现了MAC层超帧机制仿真算法,对IEEE802.15.4标准的MAC层超帧机制进行仿真。构建了一个可以利用可视化界面定制应用场景,计算应用不同超帧结构时的网络性能,并据此对超帧结构提出优化建议的仿真平台,为优化超帧结构提供了一种新思路,同时也为下一代新型网络协议的产生提供理论依据。

Abstract: At present, studies on real-time performance and reliability of WSN are mostly based on the performance analysis, protocol optimization or mathematical modeling with IEEE 802.15.4 standard MAC Protocol. However, there is no concern about the large impact on the network real-time and reliability caused by duration of the competitive access control phase (CAP) and non-competitive access control stage (CFP) in the IEEE 802.15.4 standard superframe structure. To solve these problems, a MAC layer superframe mechanism simulation algorithm was designed and implemented to simulate the IEEE802.15.4 standard MAC-layer superframe mechanism by establishing a state machine model. This design also built a simulation platform which could use visual interface to customize the application scenarios, and compute the network performance when using different superframe structure. As a result, the platform can offer the optimized recommendations for superframe structure. This research provides a new solution for optimizing the superframe structure. Moreover, it also establishes theoretical basis for next generation of the network protocols.
