摘要
详细分析了无线传感网操作系统的硬件平台环境、自身特点和基本功能,提出了一种合理划分内核层与服务层功能的操作系统整体架构及内核结构.该内核结构采用数据融合加强对精度要求较高的时钟同步任务的支持.给出了相关内核服务例程和基本的数据结构的设计.试验数据表明,数据融合后时钟同步算法中的多跳误差累积得到明显降低.*
Detailed analysis is made on wireless sensor network （WSN） OS hardware platform environment, system features and basic functions, and a novel OS architecture providing reasonable function division between kernel level and service level is proposed. A kernel structure is presented, which adopts data fusion to support precision-demanding clock synchronization tasks. Relative kernel service routines and basic data structures are carefully designed. Experimental results suggest that the multi-tlop error accumulation of the clock synchronization algorithm is reduced after data fusion.
