无线体域网络(WBAN)是一种智能无线监测系统，由可穿戴的、可植入人体的计算设备组成。它们用于支持医疗、健身、体育、军事和消费电子领域的各种个性化、高级和集成应用。在WBAN中，由于身体节点能量供应的限制，网络寿命是一个重大挑战。因此，路由协议可以在使此类网络节能的过程中发挥关键作用。在这项工作中，我们展示了一个路由协议和一个有效的主体节点协调器(BNC)部署策略可以显著地影响网络的生命周期。我们的初步工作表明，BNC在WBAN中的放置位置的变化可能会显著改变整个网络的生命周期。这促使我们在WBAN中研究一种有效的BNC节点布局策略；因此，我们提出了三种不同的BNC布局算法，考虑了WBAN中现有节能路由协议的不同特点。仿真结果表明，这些算法与合适的路由协议相结合，可以将网络寿命延长47.45%。
Wireless body area networks (WBANs) are intelligent wireless monitoring systems, consisting of wearable, and implantable computing devices on or in the human body. They are used to support a variety of personalized, advanced, and integrated applications in the field of medical, fitness, sports, military, and consumer electronics. In a WBAN, network longevity is a major challenge due to the limitation of the availability of energy supply in body nodes. Therefore, routing protocols can play a key role towards making such networks energy efficient. In this work, we exhibit that a routing protocol together with an effective body node coordinator (BNC) deployment strategy can influence the network lifetime eminently. Our initial work shows that the variation in the placement of a BNC within a WBAN could significantly vary the overall network lifetime. This motivated us to work on an effective node placement strategy for a BNC, within a WBAN; and thus we propose three different BNC placement algorithms considering different features of available energy efficient routing protocols in a WBAN. Our simulation results show that these algorithms along with an appropriate routing protocol can prolong the network lifetime by up to 47.45%.
