能量采集型无线传感网中应用驱动型资源调度算法研究

In the recent decade, energy harvesting wireless sensor networks (EHWSNs) have drawn increasing attentions for its advantages in the ability for harvesting energy from the ambient environment to enhance the network sustainability. The harvested energy introduces a new dimension into the design of network resource allocation including sampling, sleep scheduling, transmission scheduling and etc. So far the existing research work on EHWSNs mainly focus on the resource allocation that utilizes the harvested energy to the upmost extent while seldom considering the characteristics of the applications. Our project focuses on the characteristics of application scenarios and then proposes an application driven resource allocation framework. We then study how the framework serves two typical application scenarios, i.e. environment monitoring and object/disaster detection applications respectively. We also conduct field experiments to evaluate the performance of our proposed resource allocation framework. The research results of this project will offer a new design framework for application driven resource allocation in EHWSNs.

能量采集型无线传感器网络(EHWSNs)可以从周围环境中采集能量显著提高网络的可持续性，近年来吸引了社会各界的广泛关注。能量采集给传感器网络睡眠调度、传输调度等一系列网络资源调度优化问题引入了新的维度并带来新的挑战。目前国内外围绕EHWSNs的研究工作主要研究如何最大效率的利用采集能量进行资源调度，在以应用驱动为主要特征的EHWSNs中并不能最大限度的使用可用能量保障服务质量。本项目抽象归纳了应用特征，针对应用特征设计应用驱动型资源调度框架。然后针对典型应用场景确立特征服务质量优化目标，定制化的进行资源调度设计。本项目的研究成果将为EHWSNs的资源调度设计提供一种新的思路。
