以Arena操作系统的设计技术为基础,构建了一个适合无线传感器网络软件动态加载的总体设计方案,详细给出了动态对象加载器的接口设计技术。该设计减小了系统运行时的内核镜像,实现了系统在运行状态下动态加载和卸载软件模块的功能,同时保证系统长时间可靠运转并具备高可配置能力,从而有利于系统软件的升级和后期维护。模块动态加载实验验证了该设计方案的可行性。
Based on the design technology of Arena operating system, an overall design scheme for dynamic loading of wireless sensor network software is constructed, and the interface design technology of dynamic object loader is given in detail. The design reduces the kernel image when the system is running and realizes the function of the system dynamically loading and unloading software modules in the running state while ensuring the reliable operation of the system for a long time and having the high configurable capability so as to be beneficial for system software upgrades and post-maintenance. The module dynamic loading experiment verifies the feasibility of this design scheme.
