AI中文摘要：
无线传感器网络（WSNs）的一个有前景的应用是对人体健康状况的监测。为此，大量小型传感器被植入人体内。这些传感器共同构成一个无线传感器网络（WBANs），监测人体的生命体征和信号；随后，这些传感器将信息发送给医生。WBAN最重要的应用是在医院环境中实现患者安全监测网络。在这种情况下，支持患者的移动性是基本需求之一，但近年来研究中对此重视不足。为这类网络中使用的单元提供所需能量的问题具有挑战性；因此，为了节省能量，采用了功耗极低且半径极小的发送/接收单元。由此产生的小发送范围导致无法支持患者的移动性。本文建议采用自组网模式建立网络，并提出一种多路径路由算法，以支持医院环境中患者的移动性。仿真结果表明，除了支持患者的移动性外，与先前提出的协议相比，使用所提出的方案可减少数据传输延迟和能量消耗；同时，根据目的节点和网络寿命的不同，提高了投递率，但增加了路由开销。
英文摘要：
One of the promising applications of wireless sensor networks (WSNs) is monitoring of the human body for health concerns. For this purpose, a large number of small sensors are implanted in the human body. These sensors altogether provide a network of wireless sensors (WBANs) and monitor the vital signs and signals of the human body; these sensors will then send this information to the doctor. The most important application of the WBAN is the implementation of the monitoring network for patient safety in the hospital environment. In this case, supporting patients' mobility is one of the basic needs, which has been underestimated in recent studies. The problem that involves providing the required energy for the units used in this type of network is challenging; for this reason, sent/received units with very low power consumption and with a very small radius are used in order to save energy. The resulting small sending range leads to the lack of support for patients' mobility. In this paper, the ad hoc mode is suggested for use to establish a network and a multipath routing algorithm for the purpose of supporting patients' mobility in a hospital setting. The results of the simulation show that, in addition to supporting patients' mobility, the use of the proposed idea instead of previously presented protocols reduces delays in data transmission and energy consumption; it also increases the delivery rate depending on the destination and the lifetime of the network, while increasing routing overhead.
