摘　　要：针对太赫兹无线个域网络中跨个域网(personal area network,PAN)通信存在的常规信道时间分配时段(normal channel time allocation period,N-CTAP)部分常规节点数据传输受干扰影响节点通信的成功率等问题,提出一种太赫兹网络的高效自适应报告方法(efficient adaptive reporting approach of terahertz network,EARA-T)。该方法将常规节点细分为正常节点和边缘节点,在节点入网前及入网后将节点类型信息及时高效地报告给所在PAN的微微网控制器(piconet coordinator,PNC),以便于PNC在时隙分配上采取有效措施降低甚至消除网间干扰对数据传输的影响。通过使用OPNET软件进行仿真验证,相较于FDP协议和FCP协议,所提方法信息报告控制开销和时延的降低分别不少于14.1%和3.7%,信息报告成功率提高了0.4%。Aiming at the problems of normal channel time allocation period(N-CTAP)existing in cross personal area network(PAN)communication in terahertz wireless personal area network,such as the success rate of node communication affected by interference in data transmission of some conventional nodes,an efficient adaptive reporting approach of terahertz network(EARA-T)is proposed.In this method,the conventional node is subdivided into normal node and edge node,and the node type information is timely and efficiently reported to the piconet coordinator(PNC)of the pan before and after the node enters the network,so that PNC can take effective measures to reduce or even eliminate the impact of inter network interference on data transmission in time slot allocation.Compared with FDP protocol and FCP protocol,the reduction of information reporting control overhead and delay of the proposed method is no less than 14.1%and 3.7%respectively,and the success rate of information reporting is improved by 0.4%.
