该文研究了双层带限制能量收获网络上的中继器放置模型。主要讨论双层带限制能量收获网络的单覆盖单连通问题,应用斯坦纳树和已知的覆盖方法,设计了相应的近似算法并且证明了算法的性能比为9.75+ε。
In this paper, we study the model of relay node placement in two-tiered constrained energy harvesting wireless sensor networks. We mainly discuss the connected single-cover problem, for which we design an approximation algorithm with a performance ratio of.
