基于信道评估的IEEE 802.15.4e TSCH快速接入方案
|
摘要
时隙信道跳频(TimeSlotted Channel Hopping,TSCH)是IEEE 802.15.4e标准中定义的接入行为技术之一。在TSCH模式下,想要加入网络的新节点需要侦听到包含网络信息的EBs,但是IEEE 802.15.4e标准没有给出与EBs相关的广播策略,而EBs的广播策略是新节点快速加入网络的关键性技术之一,目前学术界虽然提出了许多解决方案,但却十分依赖于网络密度,且没有考虑实际中的干扰。为此,文中主要研究了TSCH在存在严重干扰的环境下的网络的形成过程,提出了基于信道评估(HSJCE)的快速接入方案,通过设计一个新的时隙帧结构对信道质量进行评估排序,同时采用新的加入节点和同步器机制增加发送的EBs数量和选择质量最优的信道来发送和侦听EBs。实验数据及其分析充分表明,新的加入和同步机制大大增加了加入节点成功侦听到EBs的概率且不依赖网络密度,即使在严重拥堵的情况下,HSJCE也能提供较短的加入时间。
Time Slotted Channel Hopping(TSCH) is one of the access behavior techniques defined in the IEEE 802.15.4 e standard.In TSCH mode,new nodes that want to join the network must listen to EBs containing network information,but the IEEE 802.15.4 e standard does not give a broadcast policy related to EBs,and the broadcast policy of EBs is a key technology for new node quickly joining the network.For the decisive technology,although the current academic community has proposed many solutions,it relies heavily on network density,and does not consider the actual interference.To this end,the paper mainly studied the network formation process of TSCH in severe interference environment,and proposed a fast access scheme based on channel estimation(HSJCE).By designing a new slot frame structure and evaluating the channel quality,The new join node and synchronizer mechanisms were used to increase the number of EBs sent and select the best quality channel to send and listen to EBs.Experimental data and analysis have fully shown that the new join and synchronization mechanism greatly increases the probability for joining nodes successfully detecting EBs and does not depend on network density.Even in the case of severe congestion,HSJCE can provide shorter join time.
