摘要: 能量捕获无线传感器网络(EH-WSNs)具有从环境中捕获能量的能力,可以无限期持续工作,因此具有非常广泛的应用前景。目前已有的大多数EH-WSNs路由方案往往侧重于如何有效地节能,而吞吐量作为EH-WSNs重要的性能指标之一却几乎没有得到考虑。首先建模出EH-WSNs端到端吞吐量最大化路由问题,为 深入了解该问题 提供理论基础,然后提出了一种EH-WSNs端到端吞吐量最大化路由方案。相比最小跳数路由方案,本路由方案能显著提高数据流的端到端吞吐量。

Abstract: Energy harvesting wireless sensor networks (EH-WSNs) have the capability of harvesting environment energy,can work forever and thus have a lot of promising applications.Most of the available routing schemes of EH-WSNs focus on selecting energy-efficient routes.Few of them consider the throughput of routes,which is clearly one of most important performance metrics.This paper first formulated the throughput-maximized routing problem for EH-WSNs so as to deeply and theoretically understand this routing problem,and then presented a throughput-maximized routing scheme.Simulation results demonstrate that,compared to the minimum-hop routing,the proposed routing scheme is able to greatly improve the throughput.
