摘 要:传感器网络是物联网和未来智能化世界的核心技术,被认为是未来与高速Internet网、高速移动通信网并列的三大信息基础设施之一,它跨越设备种类多,需求多样性强,工作环境差异性大,对软件设计和软硬件交互都提出了较高要求。本文设计并实现了一套基于服务组件架构的可重构低功耗传感网内核,通过服务组件架构和层次化解决了平台差异性和多样外设的问题,并在此基础上支持可重构快速组装应用系统;成功融合了基于事件的模式和基于任务的模式;并且创立了基于任务未来执行时刻的任务调度,简明高效地平衡了复杂的优先级调度设计和受限资源之间的矛盾,且可很好地支持低功耗调度需求。超过20个例程说明本系统设计思路可行、能够在实际中很好地满足用户需求,是未来传感网和物联网研究部署的重要备选软件平台,可有效促进该领域发展。Wireless Sensor Network is considered one of the critical technologies in future world, and to be the most fundamental information foundation with high speed Internet 2 and high speed wireless mobile networks. However, as the frontier between physical world and human world, the sensor networks have to cover different hardware transducers and devices, and overcome the highly diversity requirements and working environment, which raises the difficulty in software design. A service component based reconfigurable low power sensor network kernel is introduced in this paper, which is based on our past 5 years work. This kernel solves the hardware diversity by component design and strict layer design. The final application can be quickly reconstructed based on the component library and this architecture. It also integrates the event based and task based model together, and provides the future running time based task scheduler. This scheduler balances the complexity priority scheduling design and limited system resources, and also the low power scheduling requirements. More than 20 testing examples illustrate the progress of this kernel's current achievements.
