Learn how to use messaging technologies to build responsive and resilient applications for mobile devices and web browsers. With this hands-on guide, you’ll use the STOMP and MQTT messaging protocols to write iOS and web applications capable of sending and receiving GPS and device sensor data, text messages, and alerts. Messaging protocols are not only simple to use, but also conserve network bandwidth, device memory, and batteries. Using this book’s step-by-step format, author Jeff Mesnil helps you work with Objective-C and JavaScript libraries, as well as the protocols. All you need to get started are basic programming skills. Understand basic messaging concepts and composition Learn two common messaging models: point-to-point and publish/subscribe Use STOMP to write an iOS application that sends GPS data, and a web app that consumes the data Build an iOS app with MQTT that tracks and broadcasts device motion data, and a web app that displays the data and sends alerts Extend STOMP to filter, prioritize, persist, and expire messages Take a complete tour of STOMP and MQTT, including features not used in the book’s sample apps

Annotation. The rapid increase in the use of the new electronic communications tool of instant messaging (IM)-expected to surpass e-mail in the near future-poses serious workplace challenges. This tool kit answers all the questions about IM, including establishing guidelines for the use of IM, overcoming security risks and productivity challenges, and managing IM as a business asset.

This exciting resource introduces the core technologies that are used for Internet messaging. The book explains how Signal protocol, the cryptographic protocol that currently dominates the field of end to end encryption (E2EE) messaging, is implemented and addresses privacy issues related to E2EE messengers. The Signal protocol and its application in WhatsApp is explored in depth, as well as the different E2EE messengers that have been made available in the last decade are also presented, including SnapChat. It addresses the notion of self-destructing messages (as originally introduced by SnapChat) and the use of metadata to perform traffic analysis. A comprehensive treatment of the underpinnings of E2EE messengers, including Pretty Good Privacy (PGP) and OpenPGP as well as Secure/Multipurpose Internet Mail Extensions (S/MIME) is given to explain the roots and origins of secure messaging, as well as the evolutionary improvements to PGP/OpenPGP and S/MIME that have been proposed in the past. In addition to the conventional approaches to secure messaging, it explains the modern approaches messengers like Signal are based on. The book helps technical professionals to understand secure and E2EE messaging on the Internet, and to put the different approaches and solutions into perspective.

Streamline your exam preparation with this two-in-one guide that covers both of the new MCITP: Enterprise Messaging Administrator exams: Designing Messaging Solutions with Microsoft Exchange Server 2007 (exam 70-237) and Deploying Messaging Solutions with Microsoft Exchange Server 2007 (exam 70-238). If you're planning an upgrade to Exchange Server 2007 or are currently designing and deploying messaging solutions with it, this book is the practical tool you need to prepare for certification and build job skills.

Building on the success of the first edition, Mobile Messaging Technologies and Services offers extensive new and revised material based upon the latest research and industry developments. While early implementations targeted person-to-person messaging, MMS has now evolved to facilitate such requirements as the mass delivery of time-sensitive messages for content-to-person messaging. This Second Edition exploits the technical maturity of MMS as it is poised to generate a wealth of new business opportunities across the mobile communications sector. The author provides the fundamental technical background required for SMS, EMS and MMS, and supports this with industry cutting-edge developments. ● Contains a revised section on the fundamentals of MMS, including an updated section on GPRS to explain current commercial implementations such as GRX applications. ● Presents the latest developments in MMS standardization, including the design of synchronized multimedia integration language (SMIL) presentations, Digital Rights Management (DRM), transcoding techniques, postcard service and support of advanced multimedia formats. ● Describes the processes for standardizing telecommunications services and technologies (3GPP, OMA, GSM Association, IETF and W3C). ● Provides updated sections on SMS, EMS and heavily revised coverage of the developments in MMS, including MMS interworking and the forthcoming MMS version 1.3. This resource will be invaluable for application developers, manufacturers, operators and content providers involved in the design and deployment of messaging services. It will also be of interest to practitioners involved in the process of standardizing telecommunications services and technologies. Postgraduate students and researchers will benefit from having access to state-of-the-art findings backed by numerous illustrative real-world examples. Includes a companion website featuring information on relevant standards, available phones and developers’ resources.
