基于BANs的通信及定位仿真实验平台OACSTPCD
Simulation Platform for Communication and Localization Based on BANs
近年来,BANs在医学检测、监测和急救等领域被广泛应用,因此BANs对医学传感器的通信和定位系统的性能也提出了更高的要求,但利用实际设备直接在体内实验的不便,给WBAN中实现实时性能的测试和定位带来极大的困难,因此,开发了一个实时的性能测试硬件平台,用于BANs的通信和定位测试.在验证平台的有效性后,通过比较分析发现,不同调制方式中,低数据速率的调制具有更好的通信性能;并且体内的信道模型比穿透体的信道模型有更好的通信性能;对于体内定位,在RSS定位算法的基础上,利用调整矩阵改进最大似然算法,并应用于沿小肠传播路径中的若干点,结果有效地验证了系统的定位算法.
In recent years,BANs have been widely used in the fields of medical detection,monitoring and first aid,and the performance of the communication and positioning system of medical sensors has been put forward higher requirements by the using of BANs.Howev-er,because it is not easy to carry out experiments on the actual equipment in vivo,it brings great difficulties to realize the real-time per-formance test and positioning in WBAN.Therefore,a real-time performance test hardware platform is developed,which is used for BANs communication and positioning test.After verifying the effectiveness of the platform,through comparison and analysis,it is found that in different modulation modes,the modulation with low data rate has better communication performance,and the channel model in vivo has better communication performance than the channel model through the body.For the internal positioning,based on the RSS localization algorithm,the adjustment matrix is used to improve the maximum likelihood algorithm and applied to several points along the small in-testine.The results effectively verify the systematic localization algorithm.
