Cloud Messaging Systems Architecture and Implementation

Mobile device has become an essential element in our day-to-day lives, even for connecting to the Internet. Consequently, web service has become extremely important to access internet services through mobile. However, security has become a major concern in the field of Mobile Web services technology and the complexity also arises in the distribution and the integration of the web services. Now-a-days the use of mobile applications customers increases notable. Researchers put on efforts to bring out the state-of-the art in mobile web services with security for accessing web services through mobile devices. However, there is no attempt made so far to secure web services at multi-level. Now-a-days mobile web services with security only are not enough, at the same time mobile web services must be an intelligent. In this paper, we have proposed a novel architecture namely Intelligent, Integrated Secure Mobile Web Services (IISMWS) to access web services through mobile devices in a secured manner.

Today, the service computing research is focusing on providing efficient solutions to the challenges of the future Internet applications. The major difference that is created by these applications is their ubiquitous on-the-move availability as cloud services. This means that the mobility is rapidly becoming a fundamental requirement of the future. In addition to that, the integration of mobile and service computing domains has enabled the existing mobile devices to offer their resources as mobile Web Services (WS). For this reason, the provisioning of mobile WS in future networks is expected to become a part of the cloud, where ubiquitous services are offered by any device. This will open new business prospects for the service providers. In this paper, we present the concept of protecting such mobile WS by using Service Level Agreements (SLA) on mobile devices. Here, we propose a framework to offer SLA negotiations and manage the Quality of Service (QoS) of the provisioned mobile WS. Furthermore, the paper explains the four primary architectural components and classifies their functions into four fundamental SLA life cycles. Also, the detailed discussion regarding each life cycle and its relation to the corresponding component(s) is provided. The research addresses some major issues of authentic and authorized access to mobile WS that might become useful as we move towards the future ubiquitous Internet.

Web Services are today a well-accepted technology. Especially in the area of Cloud Computing, Web Services usually provide one of the building blocks of the used technology. Another driving technology nowadays are mobile devices. Nevertheless, there is not much research conducted yet in bringing these two important technologies together, e.g. with respect to providing Web Services on mobile devices. While there is already some technology that allows to deploy Web Services directly on mobile devices, it seems that there is still a lack of research about use-cases and/or scenarios that benefit from mobile Web Services. Therefore, this paper presents an approach that allows the evaluation of both, the technology for providing Web Service on mobile devices and mobile Web Services themselves.

There are many mobile web servers that can be used, whether it is a mobile web server that is free or paid. This research aims to analyze the quality of three mobile web servers consisting of one paid mobile web server and two other web servers that are obtained free of charge. To measure the quality of a mobile web server in this study using Apache JMeter tools and Web Application Performance Testing (WAPT). Based on the results of testing, it was found that the quality of paid mobile web servers was better compared to the quality of free mobile web servers based on values obtained using Apache JMeter, paid mobile web server is faster looking from sample times, latency and connect time result. When tested using WAPT, paid mobile servers also have better results based on the value of successful hits and average response time. The results of this assessment will depend on the type of smartphone that uses in the implementation hardware, so the value of the test results can be different if implemented on a different smartphone.

Since many service providers are providing similar web services, finding an accurate web service based on user preferences is becoming a challenging task. Therefore, enhancing web service discovery (WSD) method will improve the searching performance. In this paper, we firstly discuss and review some existing web service discovery approaches and identify their limitations. Subsequently, we propose a web service discovery method for cloud-based mobile application by using multi-level clustering technique to improve performance by reducing the searching scope. Our web service discovery architecture is able to increase the discoverability of more accurate web services based on user's preferences. Meanwhile, user preference Quality of Services (QoS) attributes are also used for ranking procedure to allow user to decide the quality of the mobile application. The experimental results show that our approach is able to increase the searching performance and provide a reliable list of selection for users.

Mobile data services in combination with profluent Web services are seemingly the path breaking domain in current information systems research. In mobile Web services sphere, resource constrained mobile terminals are used as both Web services clients and providers. While service delivery and management from Mobile Host are technically feasible, the ability to provide proper quality of service (QoS) and discovery mechanisms for the huge number of services possible with Mobile Hosts is observed to be very critical. We have studied the security, scalability and discovery aspects of the mobile Web services and the analysis has identified the necessity of a mediation framework. This paper summarizes our QoS and discovery research and discusses the realization details and features of our enterprise service bus technology based integration framework for mobile Web service provisioning.

Security issues have become a major issue on the Internet. One of the security methods that are widely used today is to implement a digital certificate. Digital certificates have evolved over time, one of which is the X.509 digital certificate. Digital certificates have been widely used as authentication applications, web network authentication and other authentication systems that require digital certificates. This research is carried out by implementing an X.509 digital certificate technology as a mobile web service with its client. Secure Hash Algorithm (SHA), Diffie-Hellman, and Advanced Encryption Standard (AES) are used to secure the data exchange transaction between the web service and mobile phone. SHA algorithm will be used for user authentication, Diffie-Hellman algorithm will be used for public key exchange and AES algorithms will be used for symmetric cryptography data. The results of the application of digital certificates, the SHA algorithm, Diffie-Hellman, and AES in mobile phone applications, provide security application running on web service.

Nowadays Personalized Service Collaboration (PSC) becomes more feasible due to the increasing availability of mobile application and web service. The semantic user model comprised of Resource Description Framework (RDF) plays a significant role in PSC. In practice, preferences within (personal data/model) often change with different time, context and dimension, which are dynamic information and contribute to PSC. Therefore, personal data model which represents time, context and dimension is increasingly required to provide a more complete user model view and more value-added user information to all relevant applications and services for PSC. In this paper, a novel personal data model based on RDF is proposed, which takes into account how to represent implicated and varied preference that corresponding to different time, context and dimension. The presented model aims to solve the issues that store, organize and represent unified personal data formally in service collaboration environment which harbors different kinds of personal date from various mobile applications and web services. Finally, the comparison and analysis between proposed personal data model and conventional user model are presented. The experiment result on real data set demonstrate the feasibility and effectiveness of proposed personal data model.

In today`s world of science & technology mobile device especially Smartphones plays the role of “"Jinn" who fulfill demand of the user. Smartphone through its Internet facility allows users to access various internet based web services ubiquitously to fulfill his/her demand. Web Services can be of two types SOAP or Restful services. Many researchers have mentioned that SOAP based services are heavy to consume on mobile device despite the fact that most of the companies still uses SOAP services but answer to this challenge is Restful Web Services. Restful services also surfers from many problems like processing of work or accessing services on device due to mobile phone`s small screen size, low processing power, less memory storage capacity etc. That`s why the heavy processing work is shifted on Cloud and only client part will be on mobile device, this integration is called as Mobile Cloud Computing (MCC). In MCC important point need to consider is to improve the performance of web services in terms of speed, memory usage and reducing latency. To resolve these issues, this paper has proposed MCC architecture. We have divided this paper is into two parts, in the first part; we did comparative analysis of Web Service consumption on mobile devices using cloud and various parameters used. In second part we have proposed architecture for mobile Web Services in Cloud which compress response data using Gzip and use of web caching to reduce overhead of repeated or previously accessed Web Service.

With the integration of mobile and Web applications, the number of services a typical mobile user accesses has grown multi-fold and this forces users to manage multiple user names and passwords daily. The same situation will be extended to ubiquitous service environments. Recently, OMA suggests a new architecture for implementing the Web Services standard for mobile environments, and SAML is recommended for user authentication and authorization on mobile Web Services. SAML is an XML based single sign-on standard, which enables the exchange of authentication, authorization, and profile information between different entities. This provides interoperability between different security services in the distributed environments including mobile and ubiquitous service environments. In this paper, we propose a single sign-on architecture in which a mobile user offers his credential information to the wired service network for obtaining user authentication and accesses to another domain using this authentication, based on the SAML standard. And we verify this architecture by checking the security messages between entities based on a messaging scenario.

A furniture rental service multinational company has a mobile application that is used by the salesperson to make sales transactions. Currently the mobile application gets data from the ERP system by importing and exporting it so that the data used is not real-time. To support the creation of real-time data communication between ERP systems and mobile applications, a replacement method for the export and import process is needed. Therefore, this study makes several web services that can be used to replace the export and import processes through the integration of Enterprise Resource Planning (ERP) with mobile applications using Service Oriented Architecture (SOA). Web services are made using RESTful and have passed several stages of testing using the QOS standard. Based on the results of testing using Jmeter with a simulation of 20 users obtained latency on the web service is 3 seconds and 4 seconds load time with an average data size of 2599 bytes so it can be concluded that this quality is quite good in terms of performance and accessibility. Test results using vooky show no bugs, but there are still shortcomings in security, which are caused by the lack of security in the header. With the results of these tests, the webservice can be used to replace the export and import process that have been used by the salesperson, so the data communication between ERP and mobile applications becomes real-time.
