EPC Cloud: Simplifying the Internet of Things Thanks to Web Patterns: HTML 5 Websockets (Part 2/3)

Part 1: Cloud & REST | Part 2: HTML5 WebSockets | Part 3: Physical Mashups

In a recent post, we were explaining how in a project common to MIT and ETH Zurich, we simplified deployments of IoT applications based on the EPC Global standards.

We operated this simplification by applying four of the Web of Things patterns: Cloud Computing, RESTful Interface, Real-Time Web and Physical Mashups.

In the first related post we described how we used Cloud Computing and RESTful Interfaces. It is now time to talk a little bit more about one of the other pattern: the Real-Time Web.

Real-Time Web: HTML 5 WebSockets to Enable Near Real-Time Applications

html5-websockets
Early on, experts of the RFID domain asked us to enable mobile or Web clients access to the raw data directly pushed by RFID readers. The challenge here is that the Web was designed mainly as a client-pull architecture, where clients can explicitly request (pull) data and receive it as a response (we have a paper about the matter, here!). This makes uses-cases where near real-time communication is required rather challenging. As an example, a typical use-case is one in which we would like to push events that are being recorded by an RFID reader directly to a mobile browser application for monitoring purpose.

Here, the “Real-time Web”, one of the most recent blueprints of the Web, can be leveraged. The Real Time Web encompasses several new techniques that can be used to push events directly to browsers. We focus on two of these here. The first one, called Comet (also called HTTP streaming or long-polling) is based on the concept of long-lasting HTTP connections and keep-alive messages. While this is supported by most browsers and HTTP libraries, it works by using an existing loop-hole. More recently, Websockets (part of the HTML5 drafts) were proposed. Websockets propose duplex communication with a single TCP/IP connection directly accessible from any compliant browser through a simple Javascript API. The increasing support for HTML5 in Web and Mobile Web browsers makes it a very good candidate for pushing data on the Web.

tpusher-logoFor the EPC Network, we created tPusher, a service that combines a RESTful API with a Web-socket and Comet server. Using
a RESTful API, clients can subscribe to RFID event notifications for a particular reader by using a URL such as:

http://.../t-pusher/reader/READER_ID


This initiates a Websocket connection with the server on which RFID events recorded by READER_ID will be pushed.

Our implementation is based on the great Atmosphere framework. Atomosphere is a Java abstraction framework for enabling push support on most Java Web servers. One of the advantages of this approach is to be able to deploy tPusher on recent Web Servers such as Grizzly, which are highly optimized to push events on the Web because of their usage of non-blocking threads for each client. In order to support browsers or other clients that do not support HTML5 Websockets yet, we use a client-side abstraction Javascript library called Atmosphere JQuery Plugin which falls back to a Comet connection in case Websockets are not supported by the client.

To better understand the impact of tPusher in the context of RFID apps let us talk about our demonstration: When setting up RFID readers or maintaining existing deployments it is valuable to have a direct feedback of the tags observed by a particular reader in order to monitor the manufacturing process or to debug the readers. In the current implementations of the EPC software stack this would require to use and configure a (expert) monitoring tool such as the Fosstrak LLRP Commander on a desktop computer. Thanks to the RESTful interface to the Real-Time Web capability of tPusher, the tags observed by any reader can now be directly pushed to any browser or HTTP library.

We developed as Mobile Web page that can display them in a user-friendly manner. The page uses HTML5, Javascript with the Atmosphere JQuery Plugin. All code required for such a page to subscribe to events pushed by readers through tPusher and display them fits within 5 lines of Javascript. The code is shown below:


// called whenever an event is pushed :
function callback(response )
{alert(response.responseBody + response.transport) ;}
// subscription to the events of reader "exit1 "
$.atmosphere.subscribe (
"http://EPC_CLOUD_APPLIANCE/t-pusher/reader/exit1" ,
callback , $.atmosphere.request =
{transport : "websocket" }) ;

Add some bits of Sencha Touch HTML and CSS and you get a nice, user friendly mobile Web application within a few hours of work. The app does not require any installation (just access a URL!) and works accross mobile Web browsers (e.g., iPhone Webkit, Android Webkit / Firefox mobile, etc.)
epc-mobile-monitor.

In a next post we will talk about the last pattern: Physical Mashups.

For those who can’t wait, you can already sneak into the presentation of the full project below.

    Understanding COSC Accreditation and Its Importance in Watchmaking
    COSC Accreditation and its Stringent Criteria
    Controle Officiel Suisse des Chronometres, or the Official Swiss Chronometer Testing Agency, is the official Swiss testing agency that verifies the precision and precision of wristwatches. COSC accreditation is a mark of superior craftsmanship and trustworthiness in chronometry. Not all watch brands follow COSC certification, such as Hublot, which instead follows to its proprietary stringent criteria with mechanisms like the UNICO calibre, reaching equivalent accuracy.

    The Art of Exact Timekeeping
    The central system of a mechanized watch involves the spring, which supplies energy as it loosens. This mechanism, however, can be prone to environmental factors that may impact its accuracy. COSC-validated movements undergo demanding testing—over fifteen days in various conditions (five positions, 3 temperatures)—to ensure their durability and dependability. The tests measure:

    Mean daily rate precision between -4 and +6 seconds.
    Mean variation, highest variation levels, and impacts of temperature variations.
    Why COSC Validation Matters
    For watch aficionados and collectors, a COSC-validated timepiece isn’t just a piece of tech but a proof to enduring excellence and accuracy. It signifies a timepiece that:

    Presents exceptional reliability and precision.
    Ensures guarantee of superiority across the whole construction of the watch.
    Is likely to retain its worth better, making it a wise investment.
    Popular Timepiece Manufacturers
    Several famous brands prioritize COSC certification for their watches, including Rolex, Omega, Breitling, and Longines, among others. Longines, for instance, presents collections like the Record and Soul, which showcase COSC-accredited movements equipped with innovative materials like silicone balance springs to boost resilience and performance.

    Historical Context and the Development of Timepieces
    The idea of the timepiece originates back to the requirement for precise timekeeping for navigation at sea, emphasized by John Harrison’s work in the eighteenth cent. Since the official establishment of COSC in 1973, the accreditation has become a standard for assessing the precision of high-end watches, sustaining a legacy of excellence in horology.

    Conclusion
    Owning a COSC-validated watch is more than an visual selection; it’s a dedication to quality and accuracy. For those valuing accuracy above all, the COSC accreditation offers peacefulness of thoughts, ensuring that each accredited watch will perform reliably under various circumstances. Whether for individual contentment or as an investment, COSC-validated timepieces distinguish themselves in the world of watchmaking, maintaining on a tradition of careful timekeeping.

    주식신용
    로드스탁과 레버리지 방식의 스탁: 투자법의 새로운 영역

    로드스탁에서 제공하는 레버리지 방식의 스탁은 주식 투자의 한 방법으로, 상당한 이익율을 목표로 하는 투자자들에게 유혹적인 선택입니다. 레버리지 사용을 사용하는 이 전략은 투자자들이 자신의 투자금을 초과하는 자금을 투자할 수 있도록 하여, 증권 장에서 더 큰 힘을 가질 수 있는 기회를 제공합니다.

    레버리지 방식의 스탁의 원리
    레버리지 방식의 스탁은 기본적으로 투자금을 대여하여 사용하는 방식입니다. 예를 들어, 100만 원의 자금으로 1,000만 원 상당의 주식을 취득할 수 있는데, 이는 투자자가 기본적인 투자 금액보다 훨씬 더 많은 주식을 사들여, 증권 가격이 상승할 경우 관련된 더 큰 수익을 가져올 수 있게 해줍니다. 하지만, 증권 값이 떨어질 경우에는 그 손해 또한 증가할 수 있으므로, 레버리지를 이용할 때는 신중하게 생각해야 합니다.

    투자 전략과 레버리지 사용
    레버리지는 특히 성장 가능성이 상당한 사업체에 적용할 때 효과적입니다. 이러한 회사에 높은 비율을 통해 투자하면, 성공할 경우 상당한 이익을 얻을 수 있지만, 반대 경우의 경우 많은 위험성도 감수하게 됩니다. 그렇기 때문에, 투자하는 사람은 자신의 리스크 관리 능력을 가진 시장 분석을 통해 통해, 어느 회사에 얼마만큼의 자본을 투자할지 선택해야 합니다.

    레버리지 사용의 이점과 위험 요소
    레버리지 방식의 스탁은 상당한 이익을 약속하지만, 그만큼 상당한 위험성 동반합니다. 증권 거래의 변동성은 예측이 어렵기 때문에, 레버리지를 이용할 때는 항상 상장 동향을 정밀하게 살펴보고, 피해를 최소화하기 위해 수 있는 전략을 세워야 합니다.
