Commercialization of the wireless body area network (WBAN) envisions future new normal for WBAN devices coexistence in a localized area. The coexistence may allow devices to freely change positions, associate, or dissociate with the neighbours as users interact. Devices’ interaction in a stationary or mobile fashion radiates heat and also competes for the limited network resources resulting to unreliable communication and other performance challenges. Besides alarming user safety, device mobility affects network performance through topology changes, which result to recursive link disconnections, energy waste, packet delay, degraded throughput, and congestion due to excessive control messaging during route repair. In this article, we propose WBAN performance optimization criteria focusing on improving energy efficiency, network throughput, and reducing the end to end delay in multiple existence schemes. Firstly, we propose an alternative routing algorithm, whose routing decision depends on a cost function considering the parameterized residue energy to node distance ratio, link energy reliability, and specific heat absorption in addition to node sequence number and hop count as fundamental route selection metrics. Secondly, we implement congestion control adaptation in the medium access control (IEEE 802.11MAC) mechanism, which improves throughput, reduces congestion, and delay. Due to link discontinuities during mobility, we demonstrate a comparative network performance to address the effect of WBAN speed at different hello intervals. The comparative analysis show, protocol implementation with a cross-layer approach outperforms the conventional protocol without MAC adaptations in terms of energy efficiency, network throughput, and a reduced end to end delay, by an average of 0.45%, 2.8%, and 13.7%, respectively.

无线人体局域网（WBAN）的商业化为WBAN设备在局部地区的共存奠定了未来的新常态。共存可以允许设备在用户交互时自由地改变位置，与邻居关联或分离。设备以固定或移动方式进行的交互会散发热量，并且还会竞争有限的网络资源，从而导致不可靠的通信和其他性能挑战。除了警告用户安全外，设备移动性还通过拓扑更改影响网络性能，这会导致递归链路断开，能量浪费，数据包延迟，吞吐量降低以及由于路由修复期间过多的控制消息传递而导致的拥塞。在本文中，我们提出了WBAN性能优化标准，重点是提高能效，网络吞吐量，并且减少了多种存在方案中的端到端延迟。首先，我们提出了一种替代路由算法，其路由决策取决于成本函数，其中考虑了参数化残差能量与节点的距离比，链路能量的可靠性以及比热吸收，此外还以节点序列号和跳数作为基本路由选择指标。其次，我们在媒体访问控制（IEEE 802.11MAC）机制中实现拥塞控制适配，从而提高吞吐量，减少拥塞和延迟。由于移动过程中链路的不连续性，我们演示了一种比较网络性能，以解决不同hello间隔下WBAN速度的影响。比较分析表明，
