Abstract

We investigate wireless sensor networks with energy harvesting and periodic data collection by mobile sinks. We propose a Markov model to study the trade-off between the value of information at the mobile sink and the cost of data collection. In particular, we focus on the impact of the limited ability of sensor nodes to collect energy by incorporating an energy buffer with discretised energy chunks as an abstraction of the battery and energy harvesting dynamics. We also use a value information framework that accounts for the timeliness of the data by discounting the value of the information at the sensor over time.

混合能量采集传感器网络的周期性数据采集

我们研究了无线传感器网络的能量收集和移动接收器的周期性数据收集。我们提出了一个马尔可夫模型来研究移动接收器的信息价值与数据收集成本之间的权衡关系。特别地，我们将重点放在传感器节点收集能量的有限能力的影响上，通过将带有离散能量块的能量缓冲作为电池和能量收集动态的抽象。我们还使用了一个价值信息框架，该框架通过对传感器上的信息随时间的价值进行贴现来说明数据的及时性。

期刊介绍： Computer and Communications networks are key infrastructures of the information society with high socio-economic value as they contribute to the correct operations of many critical services (from healthcare to finance and transportation). Internet is the core of today''s computer-communication infrastructures. This has transformed the Internet, from a robust network for data transfer between computers, to a global, content-rich, communication and information system where contents are increasingly generated by the users, and distributed according to human social relations. Next-generation network technologies, architectures and protocols are therefore required to overcome the limitations of the legacy Internet and add new capabilities and services. The future Internet should be ubiquitous, secure, resilient, and closer to human communication paradigms. Computer Communications is a peer-reviewed international journal that publishes high-quality scientific articles (both theory and practice) and survey papers covering all aspects of future computer communication networks (on all layers, except the physical layer), with a special attention to the evolution of the Internet architecture, protocols, services, and applications.
