摘要
针对现有跨PAN数据传输机制存在的业务量分布不均衡造成的时隙浪费、协调超帧开始时刻不明确、超帧统一机制所需控制开销较大等问题,提出了一种高时隙利用率太赫兹无线个域网跨PAN数据传输机制HTSU-PAN(high time slot utilization cross PAN data transmission protocol for terahertz wireless personal area network)。该协议通过采用隐式TDMA时隙分配、基于无beacon的空闲时段启用以及基于网桥节点超帧统一这三种新机制,有效提高时隙利用率,降低数据传输时延从而提升网络吞吐量。
Aiming at the problems existing in the inter-PAN data transmission mechanism,such as the time slot wastage caused by unbalanced traffic distribution,ambiguous start time of coordinated superframe,and large control overhead of the existing trans-PAN data transmission mechanism,this paper proposed a high time slot utilization cross PAN data transmission protocol for terahertz wireless personal area network(HTSU-PAN).Through implicit time slot allocation of TDMA,idle time without beacon and superframe unification of bridge nodes,the protocol can effectively improve slot utilization,reduce data transmission delay and improve network throughput.
