NEW APPROACH TO DEVELOP THE MESSENGER APPLICATION: FROM CLIENTSERVER DESIGN T...
This document proposes a new approach to developing messenger applications by combining client-server and P2P architectures. It introduces a local proxy model where each client has a local proxy that interacts with the client like a server but shares information with other proxies via a P2P system. This allows keeping the client-server protocol design while implementing it with P2P communication. As a case study, the document develops a P2P messenger application using this approach where local proxies store and share messages and user information as files in a shared folder using the P2P subsystem. The approach was implemented and tested with a simple text-based messenger application, demonstrating it can provide the same functionality as a client-server version with improved performance and scal
Web service architecture
The document provides an overview of web service architecture, including definitions of key concepts like SOAP, WSDL, and UDDI. SOAP defines the message format for web services communication. WSDL describes web services interfaces and operations. UDDI provides a registry for businesses to publish and discover web services. The architecture supports publishing services, finding services, and binding/invoking services at runtime.

The event flow is described, starting with a client request to the Loan Broker which triggers credit checks and requests loan quotes from various banks before returning the best offer to the client. Key aspects of the Mule implementation are outlined, including using messages, endpoints, and transformations to integrate the components over various transports.
Mule real world old
Mule is used to implement an ESB that aggregates loan quotes from multiple banks. It uses Mule transports like JMS, HTTP, VM, and SOAP to connect various components. These include a LoanBroker service, CreditAgency, LenderService, and multiple Bank components. Messages are routed between components, transforming data and aggregating responses to return the best loan quote to the client.

- A SOAP request contains an envelope with a header and body, while a response contains a header, body, and potential fault message.
Subscription based control system to automate management of events for robots
This document proposes a subscription-based control system using websockets to automate event management for robots. The current polling method used in human-machine interfaces restricts automation capabilities. The proposed system allows clients to subscribe to events and receive asynchronous updates from the server, making responses more reliable. It also explores using semantic web technologies to enable coordinated multi-robot activities through ontologies and web services.

L0704065070
This document presents an approach for composing semantic web services using agents in a mobile ad hoc network (MANET). It proposes an ontology-based framework where JADE agents can link web services and agents to enable semantic web applications. The approach involves three phases - service registration, construction of a service graph by matching input/output parameters, and service discovery and composition. It describes using three sample agents (TrainNameService, TrainNumberService, CompositeTrainService) to demonstrate how the composition works. The composed web services are then shown to work properly when accessed over the MANET architecture. The approach aims to automate web service composition by semantically matching parameters.
Real world integration using mule
