论文摘要
我们研究了层次的异构雷利褪色无线传感器网络（WSN），其中传感器节点监视一个感兴趣的区域（ROI），并使用接入点（AP）作为继电器，以将其感应信息传输到基站（BSS）。通过考虑雷利褪色引起的大规模路径损失信号衰减和小规模信号变化，我们将节点部署问题作为优化问题，旨在最大程度地减少网络的无线通信功率消耗。鉴于所有无线链接上的奇异能力限制，我们研究了最佳AP和BS部署的必要条件。然后以迭代算法的形式组装这些必要条件以部署节点。最后，我们确定了我们提出的节点部署算法对文献中类似方法的功效和优势。
We study a hierarchical heterogeneous Rayleigh fading wireless sensor network (WSN) in which sensor nodes surveil a region of interest (RoI) and use access points (APs) as relays to transmit their sensed information to base stations (BSs). By considering both large-scale path-loss signal attenuation and small-scale signal variation due to Rayleigh fading, we formulate the node deployment problem as an optimization problem intended to minimize the network's wireless communication power consumption. Given ergodic capacity constraints on all wireless links, we study the necessary conditions for an optimal AP and BS deployment. These necessary conditions are then assembled in the form of an iterative algorithm to deploy nodes. Finally, we establish the efficacy and superiority of our proposed node deployment algorithm against similar methods in the literature.
