Recently, wireless body area network (WBAN) becomes a hot research topic in the advanced healthcare system. The WBAN plays a vital role in monitoring the physiological parameters of the human body with sensors. The sensors are small in size, and it has a small-sized battery with limited life. Hence, the energy is limited in the multi-hop routing process. The patient data is collected by the sensor, and the data are transmitted with high energy consumption. It causes failure in the data transmission path. To avoid this, the data transmission process should be optimized. This paper presents an advanced authentication and energy-efficient routing protocol (AAERP) for optimal routing paths in WBAN. Patients’ data are aggregated from the WBAN through the IoMT devices in the initial stage. To secure the patient’s private data, a hybrid mechanism of the elliptic curve cryptosystem (ECC) and Paillier cryptosystem is proposed for the data encryption process. Data security is improved by authenticating the data before transmission using an encryption algorithm. Before the routing process, the data encryption approach converts the original plain text data into ciphertext data. This encryption approach assists in avoiding intrusions in the network system. The encrypted data are optimally routed with the help of the teamwork optimization algorithm (TOA) approach. The optimal path selection using this optimization technique improves the effectiveness and robustness of the system. The experimental setup is performed by using Python software. The efficacy of the proposed model is evaluated by solving parameters like network lifetime, network throughput, residual energy, success rate, number of packets received, number of packets sent, and number of packets dropped. The performance of the proposed model is measured by comparing the obtained results with several existing models.

近年来，无线体域网（WBAN）成为先进医疗保健系统的研究热点。 WBAN在利用传感器监测人体生理参数方面发挥着至关重要的作用。传感器尺寸小，电池尺寸小，寿命有限。因此，多跳路由过程中的能量是有限的。患者数据由传感器采集，数据传输能耗较高。它会导致数据传输路径出现故障。为了避免这种情况，应该优化数据传输过程。本文提出了一种用于 WBAN 中最佳路由路径的高级身份验证和节能路由协议 (AAERP)。在初始阶段，患者的数据是通过 IoMT 设备从 WBAN 聚合的。为了保护患者的隐私数据，提出了椭圆曲线密码系统（ECC）和Paillier密码系统的混合机制来进行数据加密过程。通过在传输前使用加密算法对数据进行身份验证，提高了数据安全性。在路由过程之前，数据加密方法将原始明文数据转换为密文数据。这种加密方法有助于避免网络系统受到入侵。借助团队优化算法 (TOA) 方法对加密数据进行最佳路由。使用这种优化技术的最佳路径选择提高了系统的有效性和鲁棒性。实验设置是使用Python软件执行的。通过求解网络寿命、网络吞吐量、剩余能量、成功率、接收数据包数量、发送数据包数量和丢弃数据包数量等参数来评估所提出模型的有效性。通过将获得的结果与几个现有模型进行比较来衡量所提出模型的性能。
