低干扰多PAN太赫兹无线个域网MAC协议

open access: yesGuangtongxin yanjiu, 2021
为解决现有多个域网(PAN)太赫兹无线个域网(WPAN)介质访问控制(MAC)协议中存在的在常规信道时间分配时段(N-CTAP)的网络间节点传输数据干扰问题,即在常规节点传输数据过程中,存在部分节点与其他网络节点互相在对方的通信范围之内,导致在传输数据时,很有可能受到干扰的问题,文章提出了一种低干扰多PAN太赫兹WPAN MAC协议(LIPAN)。通过将常规节点分类提出边缘节点类型概念,找出会产生干扰的常规节点;自适应常规节点类型报告机制,将常规节点的节点类型告知微微网协调器(PNC ...
