Design and Implementation of the Sense Egypt Platform for Real-Time Analysis of IoT Data Streams

Nowadays, we experience an abundance of Internet of Things middleware solutions that make the sensors and the actuators are able to connect to the Internet. These solutions, referred to as platforms to gain a widespread adoption, have to meet the expectations of different players in the IoT ecosystem, including devices [1]. Low cost devices are easily able to connect wirelessly to the Internet, from handhelds to coffee machines, also known as Internet of Things (IoT). This research describes the methodology and the development process of creating an IoT platform. This paper also presents the architecture and implementation for the IoT platform. The goal of this research is to develop an analytics engine which can gather sensor data from different devices and provide the ability to gain meaningful information from IoT data and act on it using machine learning algorithms. The proposed system is introducing the use of a messaging system to improve the overall system performance as well as provide easy scalability.

Analysis of the Framework of Microsoft DNA

Microsoft DNA(Distributed interNet Application) has p rovided a effective framework of combination PC with the Internet perfectly; In addition, this open framework hase also given the integration of multilingual co mponents a strong managing platform. This article has deeply analysed the main technologys of Microsoft DNA, involve COM basic technology, framework of DNA, Microfost UDA(Universal Data Access),com ponent management with COM+, asynchronous communication with MSMQ(M icrosoft Message Queue). In addition, based on a comparative analysise with the C/S(Client/Server) framework, the author has illustrated the excellency of the Multi-tier framework of Microsoft DNA.

Integration of Enterprise Resource Planning System Based on SOAP

While the enterprise resource planning (ERP) systems become more and more complex, the traditional tools such as DCOM, CORBA or EJB encounter more difficulties than before especially when heterogenous and distributed environment and multiple companies are involved. The newly born international specification SOAP brings a new solution to ERP because of its simplicity and high extensibility. This paper analyses the techniques to extend basic SOAP to implement ERP system. The techniques, including data envelope, dynamically and loosely coupled remote process calling (RPC), support to the multiple communication protocol, and security and performance improvement, greatly enhance the ability of basic SOAP and make it capable to accomplish the integration task in large scale ERP systems. All the techniques we discusse here are successfully utilized in the ERP system in the Three Gorge Cascade Dispatch Center of China Three Gorge Project Corporation.

基于多通信协议的一码通乘平台技术研究

近年来,随着公共交通领域大数据、云计算、移动支付等新兴科技的应用,城市公交、轨道交通等公共交通行业都推出了二维码App实现了“刷手机”乘车。在为用户出行带来便捷的同时,出现了各App平台的信息数据不互联互通和二维码规范不一等问题。这给用户换乘交通工具时带来了不便,同时增加了交通部门的管理成本。本文基于HTTPS(Hyper Text Transfer Protocol over Secure Socket Layer)通信协议、HTML5(HyperText Markup Language 5)通信协议以及MQ(Message Queue)通信协议等多种通信协议构建一码通乘平台,统一各平台的二维码规范和对信息数据,让公共交通资源和数据管理朝着高效化、便捷化、规范化的方向发展。

A Communication Method of Distributed Tactical Training Simulation System Suitable for Remote Interconnection

The traditional distributed tactical training simulation system is limited by the availability and bandwidth of military network transmission channel and does not have the feasibility of remote interconnection and spatial sub-regional deployment.In this paper,a new communication method of distributed tactical training simulation system is proposed to solve the problem of strong business coupling between nodes and system availability under the condition of low bandwidth.The operator of federated exchange,federated queue and their concepts and design requirements are firstly proposed,and the inverted tree,triangle,ring exchange topology and circular queue structure are further constructed.Theoretically,the expected goal of high-speed interworking between nodes in the cluster and high reliable transmission between clusters is realized.The example also shows that this method can significantly improve the throughput of single switching node and federated node after using reliability confirmation mechanism.
