摘　　要：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(LI-PAN)。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);常规节点时隙分配新机制,使得PNC按照常规节点类型分配时隙资源,从而降低常规节点在数据传输过程中所受到的干扰,有效提高了数据传输的成功率以及网络吞吐量,减少了平均时延。Some nodes and other network nodes are within the communication range of each other in the normal data transmission process,which may lead to interference in the data transmission.In order to solve the problem of data interference in the Media Access Control(MAC)protocol of multi-Personal Area Network(PAN)Terahertz Wireless PAN(WPAN)in the normal channel time allocation period,a low interference multi-PAN MAC protocol for Terahertz WPAN is proposed.By classifying normal nodes,the concept of edge node type is proposed to find out the normal nodes that may cause interference.Adaptive normal node type reporting mechanism is applied,which may inform the Piconet Coordinator(PNC)of the node type of the normal node.A new mechanism for normal node slot allocation is also used,which enable the PNC to allocation slot resources according to the normal type.Therefore,the interference of conventional nodes in the process of data transmission is reduced.The data transmission success rate and network throughput are improved effectively,and the average delay is reduced.
