OpenWSN 1.0 RC for GAINZ Released! (20091128 )
各位朋友：OpenWSN传感器网络操作系统1.0RC版现在已经可以到 googlecode 上免费下载了！下载地址：
http://code.google.com/p/openwsn/
这一版本是在2007年openwsn-0.5版本（下载超过4300次）的基础上经过较大调整、扩充和改进之后形成的最新版本，运行平台缺省为中科院宁 波所的GAINZ硬件平台（基于Atmega128和cc2420 transceiver），并提供了超过20个示例演示如何使用（以后仍会继续增加），包括网络化数据收集的演示。openwsn完全基于ANSI C开发，可方便的移植到各个硬件平台并与现有各种操作系统相融合，避免了TinyOS的nesC与宿主操作系统和遗留C代码的相互调用问题，可最大限度地 利用工业界广泛存在的C资源（大量成熟的C代码和技术支持、熟练的C程序员资源等），并以ANSI C的语法支持了事件驱动模型和基于服务的组件架构。
按照我们的预测，在未来世界中，以大量微型无线传感器为代表的末端无线感知网（或称之传感网）、以智能手机为代表的高速移动通信网、以Internet2 为代表的高速骨干通信网将构成未来社会的基础信息设施，而其它各种网络将走向消亡或与上述三个层次的网络相融合。我们希望，OpenWSN能在这一趋势中 占据感知网这1/3，驱动各种无线传感器使之更好的为社会服务，并成为事实上的主流传感器网络操作系统和基础平台。
OpenWSN的代码完全自主开发，前后断断续续共历时4年，吸取了许多在工程实践中被验证过的成果和模式，尽管本次发布仍然被定位为正式发布前的 Release Candidate（RC）版，但是其中的许多代码已经完全可以实用。即使是对普通的微控制器类嵌入式系统开发，也极具参考和复用价值。正式版本将在进一 步收集反馈意见并修正bug后再行发布。我们欢迎大家下载并广泛试用，并通过google code提交您的反馈意见，或直接反馈给openwsn # gmail.com。

Dear All:
I'm pleased to announce the new version release of OpenWSN! You can download openwsn-1.0rc at:
http://code.google.com/p/openwsn/
OpenWSN means Open Wireless Sensor Networks. It's an open source platform for both academic research and real industry applications. It
was expected to be widely accepted in the society and to powers the smart sensor to make us live better. According to our prediction, the huge number of smart sensors will become an important infrastructure like 3G and Internet 2 in the future. While, while, OpenWSN was hoped to powers 1/3 of them :)
OpenWSN is designed to be an event based and service-oriented WSN OS. It has a event dispatching kernel "osx" and a lot of service objects which can accept events input. Thanks for its highly flexible architecture, you can kick off the components which are not useful in your application, even the "osx" kernel service itself. Please refer to http://code.google.com/p/openwsn/ for more detail.
Attention this is still a release candidate version, but it's ready for work and demonstrate. The formal release 1.0 without "rc" will be probably released in March 2010.
The designer and organizer of OpenWSN project is Dr. Wei Zhang. He's with Dept. of Control Science and Engineering, TongJi University, which is a hundred year university in China since 1907. His interests include the fundamental techniques in wireless sensor networks, complex networks behaviors, and intelligent data analysis. Currently, he focus on sensor network platforms & applications. You can contact him through openwsn#gmail$com.
Sincerely
- Wei
