摘 要
本文给出了一套适用于无线传感网络应用的软件平台解决方案,该软件平台利用本中心研发的无线传感网络节点,基于 IEEE 协议,具有较强的可扩展性和可移植性,可以用于无线传感网络软件二次开发和硬件功能验证。
本文首先介绍了无线传感网络的概念与背景,从军事国防、工农业、城市管理、生物医疗、环境监测、防恐反恐和危险区域远程控制等领域综述了当前无线传感器网络的研究进展。
接着对该软件平台的设计思想与框架做了详细的说明与论证,进而给出了各层次代码的分配原则。该原则不仅适用于本设计中的代码,也为在此基础上二次开发的程序提供了设计规范。结合 IEEE 标准体系结构, 确定了物理层与 MAC 层的层次划分。
之后,详述了物理层与 MAC 层的设计。物理层主要包括 SPI 接口、 UART 2420 接口,以驱动的形式表现;MAC 层则包含了数据接口与管理接口,这些接口以函数的形式表现,并尽可能与 IEEE 规范中的原语定义相一致。对于这些函数,本文给出其功能描述、函数原型、参数及返回值,同时也是对 IEEE 规范中原语的阐述。
最后,给出了该软件平台的应用流程,包括非信标使能网络创建、非信标使能网络的扫描与联网、信标使能网络扫描和同步、孤立处理、直接数据传输、间接数据传输、数据轮询和清除等流程,并给出测试结果。

Abstract
In this paper, we design a software platform solution for wireless work applications, which use the wireless work nodes developed by the Centre. Based on the IEEE agreement, with strong scalability and transplantable, the platform can be used for wireless work software and hardware development of secondary functional verification.
This paper first introduce the concept of wireless works and background, from the military and national defense, industry and agriculture, urban management, bio-medical, environmental monitoring, prevention and suppression of terrorism and dangerous region in areas such as remote control.
Then we do a detailed explanation for the design of the software platform and give a framework at all levels of code distribution. The principle applies not only to the design of the code, but also to a secondary development on the basis of the platform. With IEEE sta
