OpenWSN项目要点> ... [More] OpenWSN致力于为无线传感器网络应用的开发提供一套基础平台，包括传感器网络操作系统，传感器网络中间件，传感器网络开发接口，以及部分测试工具。目前的工作主要集中在传感器网络操作系统，包括硬件层、事件调度器、应用程序开发框架、调试和输入输出支持、协议栈等。 > OpenWSN是一个严谨的实用平台而非新想法的验证平台。从诞生之日起，OpenWSN就把能否实用作为第一目标，并把与过去工业界大量遗留C代码的兼容性和重复利用性作为重要任务。因此，OpenWSN规定自己必须采用ANSI C语法规范，以保证能够最大限度的在不同厂家的硬件平台上经编译后即可运行。但是，OpenWSN的模块化结构使其同样可称为良好的研究平台进行功能性扩展和新想法的实验 > OpenWSN采用严格的分层设计，同TinyOS一样提供了非剥夺式事件调度内核，并提供了基于可编程服务模式的应用程序框架简化开发，可与其它C程序库或RTOS（如uCOS或uClinux）无缝配合使用，也可单独使用。 > 目前缺省的OpenWSN开发平台为ICT GAINZ 2.4G结点，基于Atmega128 MCU和TI/Chipcon's cc2420 transceiver。由于硬件架构基本类同Crossbow MICAZ，开发者可自行修改HAL层完成向MICAZ的移植(因我们没有购买MICAZ硬件)。对其它硬件平台，可能需要在HAL层做较多的工作，甚至替换整个HAL层。软件开发平台目前为WinAVR和AVR Studio 4.x 版本（我们一直在更新）。 > 在文档不能跟上之前，请大家阅读有关示例代码进行学习，这些代码同样也是测试代码。但是，由于OpenWSN核心一直在演化之中，所以很可能造成示例程序无法编译通过，遇此情况，请参照核心代码相应模块API修改示例程序或与我们联系。 > 同济大学OpenWSN Group将致力于维护OpenWSN最底层的平台，接受大家的贡献并决定是否最终纳入内核还是作为外围服务库发布，以保证OpenWSN内核的精简性并延续我们的设计理念；同时，我们也将致力于提高内核部分的可靠性，使其能够进入关键应用领域，并为大家的应用开发提供可靠的支持。OpenWSN已经用于我们的教学和项目实践中，将作为我们一项长期的工作延续下去。 > OpenWSN的license管理采用类似MySQL的Dual License方式，免费版本遵从GPL License开源协议，并请保留其中的版权声明和作者声明，商用请联系openwsn group，其中的收益将用于继续支持OpenWSN的发展。对非盈利性应用（包括学校和科研院所将其用于教学和非盈利性科研项目、个人将其用于学习和非商业性使用）是完全开源和免费的。 Support This Project > 在OpenWSN主站（原基于google site，现无法访问）恢复之前，本网站将代行主站功能，用于发布各种消息。 Notice from OpenWSN This site is the main code site of openwsn project. The "OpenWSN" on sourceforge.net has only a link to here. The new version is still in developing based on ICT's GAINZ hardware platform which is using Atmega128 and TI/Chipcon's cc2420 transceiver. You can simply open the projects by AVR Studio. Most of the Hardware abstraction layer are tested. The new version's source code will be uploaded to this site after re-formmatted. This will be in the next month. You can downloaded them through subversion's client software such as TortoiseSVN. The old 2007 version is based on LPC2136(ARM7). We will merge they two in a new single version in the future. Since I'm busy and haven't much time to prepare the documents, I suggest you read the examples/testing demos first. Most pages in this site are also obsolete. I'll update them later. -- 2009.10.22 ..... OpenWSN means Open Wireless Sensor Networks. It's a fundamental platform for WSN research and applications. It was initiated by TongJi-University firstly and now we have members from Bradford, SJTU, Beihang, NWPU, etc. The current version of OpenWSN hardware is based on LPC213x/LPC214x ARM7 + TI/Chipcon cc2420. They contains 8-32K SRAM and 64-512K Flash.

Forum OpenWSN on GoogleGroups Source Code download News Nov, 2007 activate the new website for openwsn http://openwsn.sensor4live.org. anyway, openwsn now has a domain name after a long time wandering in the cyberspace. July, 2007 add new downloadable package all-in-one.zip (about 3MB). this can facilitate your developing if you're new to openwsn developing. refer to its 'note.txt' first for upgrading instructions. the developers stronly recommend you to install some SVN client and update the source often.

Wireless Sensor Networks' project.

ActiveCloud is a middleware for fast and flexible creation and deployment of applications using an heterogeneus set of data sources, such as those typically found on an ubicomp environment, with an ... [More] emphasis on Wireless Sensor and Actuator Networks (WSANs). ActiveCloud allows the developer to focus on the application and forget about low level details like new hardware support, communication with different devices, event polling, network administration and result notification. The main architecture of ActiveCloud is designed with extensibility in mind; allowing the application developer to seamlessly add new hardware by using the right "capsule" to add support for a new device at runtime. Also, the integrated notification service allows making simple WSAN applications without writing a single line of code. ActiveCloud is part of the UbiSOA family of projects, along with TinySOA, which bring WSN and ubicomp technologies into the mainstream. [Less]

This open source project aims at building a JAVA API and implementation of the SWE (Sensor Web Enablement) Common Data Model, that can be easily used to access and produce SWE Common Data, and convert ... [More] in to/from existing formats such as NetCDF, HDF, GeoTIFF, JPEG2000, etc... It can also be used to quickly develop SWE services such as SOS, SPS and SAS which all rely on the SWE Common Data Model and thus to build a Sensor Network. The project was initiated by the VAST Team at the University of Alabama in Huntsville (UAH) and is now also maintained by Sensia Software, Spot Image, and Botts Innovative Research, Inc.. DependenciesThe following libraries are needed in order to compile the code published on SVN or in the download section: Xerces J 2.9.0 - XML Parser Vecmath library extracted from Java3D 1.4 JTS 1.8 - Java Topology Library StAX API and a working implementation For dealing with existing data formats, the following libraries are also needed: JAI & ImageIO 1.1 if not already included in your JDK - Java Advanced Imaging JJ2000 5.1 - JPEG 2000 support NetCDF Java Library - NetCDF data library [Less]

Simple STL for Wireless Sensor Network

The Re-Mote Testbed Framework is a collection of modules for providing remote access to wireless sensor network testbeds with a main focus on modularity, abstraction levels, and responsiveness. The ... [More] components of the framework fall into three categories: Client software, server software and host/gateway software. The client is a Java based GUI featuring mote console windows useful for debugging applications. The server software consists of a mote server daemon written in C++, a relational database based on MySQL, and a mote information server based on Apache Tomcat and Axis. The host software is a mote host daemon written in C++ with site specific configuration in shell scripts. Getting StartedIf you are using the Re-Mote client basic information is available in the UserManual. If you are deploying a testbed see the AdministratorManual and read the SecurityConsiderations. If you want to contribute read the DeveloperManual and take a look at the RoadMap to get an idea of what needs work. Questions and Bug ReportingQuestions can be mailed to the mailing list. All discussions related to testbeds and sensor networks are welcome. Note, first time posters are moderated to prevent spam. If you found a bug in the client or one of the other components, please enter it into the issue tracker. If the bug has already been reported you are encouraged to add extra information as a comment. This will help to confirm that it is reproducible and raise the attention of developers. CreditThe project is being developed in collaboration between DIKU and CIT and headed by Jonas Fonseca and Rostislav Špinar. The initial work was done by Jan Flora and Esben Zeuthen at DIKU under the supervision of Philippe Bonnet. The Re-Mote Testbed Framework has been developed in the context of Embedded WiSeNts and has further been developed in the context of the CRUISE IST. [Less]
