摘要: 为满足无线实时定位系统实时性和节点动态加入的要求,充分提高信道利用率,提出了一种多区域多目标TOA实时定位系统信道分配协议(ZTDMA),将定位系统覆盖区域划分为若干互不干扰的定位子区域并行工作,缩短节点的平均定位周期,可以及时地检测到定位目标的加入和退出,动态地为其分配定位时隙,保证系统实时性。通过OMNet++仿真平台对协议进行仿真,验证了实时性优势。

Abstract: In order to meet the needs of real-time and dynamic joining of nodes in wireless real-time geolocation system,fully improve the channel utilization rate,this paper proposed a specific ZTDMA protocol that divides the geolocation system coverage area into several independent subdomain which can work in parallel.ZTDMA can shorten the average localization period of nodes effectively,and detect the joining and exiting of target nodes in time,dynamically allocate time slot for them,ensure real-time of the system.Then we simulated the ZTDMA protocol using OMNet++ simulation platform,in order to prove the superiority of real-time characteristic.

Key words: Multi-zones,Multi-objective,Real-time geolocation system,Channel utilization
