摘要: 针对WIA-PA星型网络中的簇首瓶颈问题,提出一种适用于WIA-PA网络的冗余簇首机制。规定冗余簇首具有最高优先级入簇,采用心跳信息、跳频技术等实现实时监测和信道的动态冗余,引入休眠机制,降低WIA-PA网络能量的消耗。通过马尔可夫模型进行可信性建模和分析,结果表明该机制具有可靠性。

Abstract: Based on the bottleneck of Cluster-Head in Wireless Networks for Industrial Automation-Process Automation(WIA-PA) star network, this paper works out a redundant cluster-head mechanism which is suitable for WIA-PA network. The mechanism provides redundant cluster-head with the supreme priority to join the cluster and uses the technologies of heart rate information, frequency-hopping and so on to achieve real-time monitoring and dynamic redundancy of channel, at the same time the introduction of sleeping mechanism greatly reduces the energy consumption of WIA-PA network. The reliability of this redundancy mechanism is theoretically proved by Markov model.

Key words: star network, redundant cluster-head, frequency-hopping, reliability
