“…CoAP is built on the top of User Datagram Protocol (UDP) and follows a request-response paradigm; -Extensible Messaging and Presence Protocol (XMPP) [18]; -MQ Telemetry Transport (MQTT) protocol [19]: a lightweight publish/subscribe protocol flowing over TCP/IP for remote sensors and control devices through low bandwidth, unreliable, or intermittent communications; -Constrained Session Initiation Protocol (CoSIP) [20,21]: a version of the Session Initiation Protocol (SIP) [22] aiming at allowing constrained devices to instantiate communication sessions in a lightweight and standard fashion. Session instantiation can include a negotiation phase of some parameters which will be used for all subsequent communication.…”

Abstract. The Internet of Things (IoT) will consist of billions of interconnected heterogeneous devices denoted as "smart objects." Smart objects are generally sensor/actuator-equipped and have constrained resources in terms of: (i) processing capabilities; (ii) available ROM/RAM; and (iii) communication reliability. To meet low-latency requirements, real-time IoT applications must rely on specific architectures designed in order to handle and process gigantic (in terms of number of sources of information and rate of received data) streams of data coming from smart objects. We refer to this smart object-generated data stream as "Big Stream," in contrast to traditional "Big Data" scenarios, where real-time constraints are not considered. In this paper, we propose a novel Cloud architecture for Big Stream applications that can efficiently handle data coming from deployed smart objects through a graph-based processing platform and deliver processed data to consumer applications with lowest latency.

“…Thus, an XFormsRTC client can send and receive data to/from an RTC server over HTTP or WebSocket. Furthermore, it is possible to use special application-level protocols, such as XMPP [49][50][51]; defined by the optional subprotocol attribute. Indeed, Pohja [45] proposes that HTTP communication should be complemented with XMPP in order to meet the communication requirements of modern Web Applications.…”

Leveraging declarative languages in web application development

Web Applications have become an omnipresent part of our daily lives. They are easy to use, but hard to develop. WYSIWYG editors, form builders, mashup editors, and markup authoring tools ease the development of Web Applications. However, more advanced Web Applications require servers-side programming, which is beyond the skills of end-user developers. In this paper, we discuss how declarative languages can simplify Web Application development and empower end-users as Web developers. We first identify nine end-user Web Application development levels ranging from simple visual customization to advanced threetier programming. Then, we propose expanding the presentation tier to support all aspects of Web Application development. We introduce a unified XForms-based framework-called XFormsDB-that supports both client-side and server-side Web Application development. Furthermore, we make a language extension proposal-called XFormsRTC-for adding true real-time communication capabilities to XForms. We also present XFormsDB Integrated Development Environment (XIDE), which assists end-users in authoring highly interactive data-driven Web Applications. XIDE supports all Web Application development levels and, especially, promotes the transition from markup authoring and snippet programming to single and unified language programming.

“…As defined in the XMPP Multi-User Chat (MUC) specification [XEP-0045], when an XMPP user (say, "juliet@example.com") wants to join a groupchat room (say, "montague@chat.example.org"), she sends a directed <presence/> stanza [RFC6121] to that chat room. In her request she also specifies the nickname she wants to use within the room (say, "JuliC"); in XMPP this room nickname is the resourcepart of an occupant JID (thus "montague@chat.example.org/JuliC").…”
