本文提出了第一个用于体内网络(INS)的声学发现体系结构(ADA)。ADA的主要目标是实时(RT)发现和询问作为IN一部分的所有植入式医疗设备(IMD)。这使得对多发性IMD患者进行非侵入性RT诊断成为可能。ADA将允许医生在移动中获得治疗患者的重要信息，并持续监测他们。根据初步的实验结果，在模拟现实智能网的网络模拟器中实现了该体系结构。ADA负责扫描人体体积，利用压电微机械超声换能器(PMUT)阵列的波束形成和波束控制能力，并有效地询问所有可到达的设备的状态。因此，完整的IN图可以与患者的所有生命体征一起重建。Ada显示了非常好的RT能力，对于60 x 30 x 20 cm(3)的躯干体积，完整的扫描时间从1500到100 ms，能量消耗从2.6到0.2 MJ，取决于扫描精度。
This article proposes the first acoustic discovery architecture (ADA) for intrabody networks (INs). The main objective of ADA is to discover and interrogate, in real-time (RT), all the implantedmedical devices (IMDs) that are part of an IN. This permits noninvasive RT diagnosis for patients with multiple IMDs. ADA will allow medical doctors to have vital information, on-the-go, for treating patients and to constantly monitor them. The architecture was implemented in a network simulator emulating a reallife IN, based on preliminary experimental results. ADA is in charge of scanning the body volume, by exploiting the beam-forming and beam-steering capability of piezoelectric micromachined ultrasonic transducers (pMUTs) arrays, and efficiently interrogating all the reached devices for their status. As a result, a full IN map can be reconstructed together with all the vital signs of a patient. ADA shows very good RT capabilities, with a full scanning time from 1500 down to 100 ms and energy consumption from 2.6 down to 0.2 mJ, depending on the scanning accuracy, for a body torso volume of 60 x 30 x 20 cm(3).
