TinyOS is an open-source operating system especially designed for wireless sensor networks. It is a component-based operating system, hence programmers can integrate only the needed components to keep the code size small. Thus it is suitable for resource-constrained sensor networks. TinyOS models an event-driven execution, and includes power management and flexible scheduling to support unpredictable wireless  communications and physical world interfaces. The component library includes "network protocols, distributed services, sensor drivers, and data acquisition tools". The components and the modules can be used as it is or can be modified to fit into the custom applications includements.

Middleware for Smart Environments [jCook:05][on going] Smart Environment Components:

• Sensor Hardware
• Sensor Software
  • Both help in perceiving/sensing the environment
• Application Software
  • Interprets and reasons about the perceived data
• Effector Control Software
  • Act on the environment
• Some Support Systems

Smart Environment Implementation Layers:

• Hardware layer
• Operating System Layer
• Middleware Layer
• Application Software Layer

Middleware Layer:

Acts between Operating System layer and Application software layer. Lies between the software applications it assists and the platform it is based on.

               <b>Middleware layer provides supports like:</b>                     <ul>                            <li> Facilitate Rapid Development                           </li><li> Easy of Integration                           </li><li> Improved Reliability                          </li><li> Increased Scalabilit                          </li><li> Transparency                          </li><li> Interoperability                      </li></ul>                  <b>Some Points</b>                  <ul>                        <li> These supports/services will help smart environment possible.                      </li><li> These middleware services may be implemented as part of the Operating System                      </li><li> Some middleware services may be implemented as part of the Application Softwares themselves                       </li><li> But to make the smart environment practical a separate and generalized middleware layer providing the above services is more desireable that can enhance rapid and easy smart application development using these service components.                     </li><li> Middleware can be a single layer above operating system or can be an additional layer on an existing middleware layer. Purpose is providing more abstractions to the applications.                        </li><li> Middleware framework is another concept that can combine more than one middleware components and services to provide additional services or to provide interoperability among those middlewares                       </li><li> From the developers viewpoint: Middleware will provide some API to be used by application developers. Also a middleware will have some protocols (rules and components supported)                 </li></ul>              <b>Evolution of Middleware:</b>             <p>Middleware is mostly about communication.</p>                <p>Step 1: using of punch card programming: using punch cards/even flipping switches for programming</p>                <p>Step 2: Using of MainFrame Computer: Computing done in a central place. Users interact through terminals</p>             <p>Step 3: File sharing architecture:  With the invent of PCs File sharing architecture evolved. PCs download files from shared locations,                  perform jobs and submit to the shared locations. Over time the PC LAN became over crowded for this paradigm.</p>                <p>Step 4: Client-server architecture evolved. File servers were replaced by database servers who respond to users requests and supply only the required data rather than total file. Network load decreased</p>                    Two Forms of Client-server architecture:                        <ol>                            <li> Two Tier                           </li><li> Three Tier                        </li></ol>              <p><b>Two Tier:</b> Client layer(Sytem Interface) and a Server layer (DBMS). An additional component that is shared by the two layers mainly for process management:initiation, conduct and publish of the results. Resource management, adjust to client's capability.</p>             <p><b>Three Tier:</b> The shared component in the two tier architecture is given the form of a 3rd layer in between client and server layers.   This additional layer takes care of</p>                 <ul>                        <li> Process Management by providing logic and rules to control job processing                      </li><li> Queueing of messages                  </li></ul>              <p>This additional layer helps in</p>                   <ul>                        <li> increasing the number of clients it can handle                     </li><li> increased performance                     </li><li> system's flexibility improvement                      </li><li> maintainability, reusability, scalability                 </li></ul>              <p>This architecture has become the basis for many middleware solutions. We can think the additional layer in between client and server layer as the middleware layer.</p>              <b>Middleware Framework:</b>                    <p>Middleware Frameworks usually target at some specific application domains. They consist of software environments that provide</p>                        <ul>                            <li> An API                         </li><li> A User Interface                          </li><li> Tools for application development                         </li><li> Tools for System Management                       </li></ul>                  <p>Frameworks can provide their own private middlewares. Frameworks can also utilize other commonly available middleware services for that application domain. For a specific domain,                   a framework usually provides better solutions than general middlewares as they are especially designed for that domain. It is usuaaly easier for the developers to use frameworks for application development and testing. Frameworks can also be called middlewares themselves because they provide the same/similar purpose. Many middlewares do not have any visible part but frameworks usually have visible parts.</p> From: http://sitestree.com/?p=5147<br /> Categories:111<br />Tags:<br /> Post Data:2010-10-05 12:42:08<br />

Just an overview.

• I took all of my short-notes from http://computer.justetc.net to http://www.justetc.net/sayedblog: wordpress blog
• How? take your categories into wp_categories table. You can take all your categories from your current web-site/source/database into wordpress in this way.
• You may bring both databases under the same MySQL host/server. Will facilitate to write queries to transfer data.
• Take all your articles/contents into wp_posts table. Map right – your table fields and wp_posts table fileds. You can use insert into wp_posts…….select…..from your table . You know what I mean………
• Create articles and categories – mapping – in wp_post2cat table
• You may update wp_categories table to reflect the number of articles under that category
• In wp_posts table- guid field need to be appropriately generated. You can write a script to create guid/actually the article url – using wordpress existing functions such as get_permalink(), and write_posts() functions
• You can also create guid manually. After you transfer your data into wp database, from wp-admin window, open each article by clicking the edit button and click on the save option. GUID will be generated. Article links will work
• You can also do such for categories. Open all categories one by one using the edit option, and then click on the save option. From your blogs the categories will also work.

I know: creating another site with the same contents is not something that search engines love. What you can do, you can point your guide to your original location if you need both. For me, I wanted to link to my short-notes from linkedin.com, linkedin.com can display your blog contents/feeds in your linkedin home page – but your blog has to be in wordpress or in blog link…so you know where I am going to. Alternatively, you can write an application for linkedin that can display feeds from your type of blogs – or you can write a very customizable application that can ask for content source/type, db type, db name, table fields, password if any, and can show contents from the source. RSS feed should work – a simple way From: http://sitestree.com/?p=5215

Required modules: Views, Date, Calendar, cck (content), Text, Node Reference, Options Widgets. You can download the modules from drupal web-site. For calendar, http://drupal.org/project/calendar. For date replace calendar with date in the previous url (http://drupal.org/project/calendar => date). For views, replace with views.

How to install: unzip and upload to the modules folder in the Drupal installation. Afterward, from Site Building -> Modules under Administration (in Drupal), check these modules (and also check them on what these modules are dependent)

How to work? Areas you need to play with to have customized calendars/event calendars for your site:

• Administer->Site Building->Views
• Site Configuration -> Date and Time
• Administer -> Content Management -> Date Tools
• You have to create calendar styles/customized calendars using the above options. The you will see an option under create content to create calendars for your web-site.
• using site building -> Blocks, you can place these calendars any where you want
• You can also embed calendars in pages
