Abstract
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.关键词
