Dedicated to the rapidly developing area of telecommunications systems (wireless communication), this book explains the essence of the standards joined together under the name WAP. It describes the main properties and distinguishing features of WAP applications, and contains a detailed description of the architecture and key elements of WAP technology: WAP browsers, WAP gateways, WAP clients, and the WAP-content server, which consists of an http server, an application server, and a database serv...

It's an increasingly wired world, but many people are finding that the best way to get connected is to do away with wires entirely. From cable replacement to universal Internet connectivity, wireless technology is changing the way we connect to our machines and to each other. As with any new technology, buying your gear is only the first step. Understanding how to make the best use of it is another story. "Wireless Hacks" offers 100 industrial-strength tips about wireless networking, contributed...

In The Embedded Internet Sergio Scaglia examines the techniques that programmers will need to learn to obtain internet connectivity for their embedded systems. Sometimes this will be relatively straight-forward, using TCP/IP stack implementations which already exist. Sometimes, this will be much more difficult, requiring whole new implementations to be developed. Either way, The Embedded Internet will be the ideal starting place for programmers to learn and develop these skills.The book is stru...

Public and private networks will eventually be configured in such a way that all voice calls are routed using Internet protocols. This book reviews existing and emerging standards for voice over IP; provides detailed guidance on how to engineer an efficient VoIP network; discusses quality of service (QoS) enforcement techniques; and shows how to prototype and test a network's performance.

Wireless connectivity is now a reality in most businesses. Yet by its nature, wireless networks are the most difficult to secure and are often the favorite target of intruders. This book provides the busy network administrator with best-practice solutions to securing the wireless network With the increased demand for mobile connectivity and the decrease in cost and in the time required for installation, wireless network connections will make up 20% of all corporate network connections by the en...

This book constitutes the thoroughly refereed post-proceedings of the First International Service Availability Symposium, ISAS 2004, held in Munich, Germany in May 2004. The 15 revised full papers presented were carefully selected from 28 submissions during two rounds of reviewing and improvement. Among the topics addressed are high availability database architectures, data persistence, dependable mobile Internet services, System Availability Forum standards, QoS control, middleware, service-lev...

The Internet of Things (IoT) usually refers to a world-wide network of interconnected heterogeneous objects (sensors, actuators, smart devices, smart objects, RFID, embedded computers, etc) uniquely addressable, based on standard communication protocols. Beyond such a definition, it is emerging a new definition of IoT seen as a loosely coupled, decentralized system of cooperating smart objects (SOs). A SO is an autonomous, physical digital object augmented with sensing/actuating, processing, sto...

Revised to reflect the rapid changes in the field of networking, Computer Networking provides a top-down approach to this study by beginning with applications-level protocols and then working down the protocol stack. An early emphasis is placed on application-layer paradigms and application programming interfaces to allow readers to get their "hands-dirty" with protocols and networking concepts in the context of applications they will use in the industry.   Networking today is much more (and f...

The first complete guide to planning, evaluating, and implementing high-value SIP trunking solutions   Most large enterprises have switched to IP telephony, and service provider backbone networks have largely converted to VoIP transport. But there’s a key missing link: most businesses still connect to their service providers via old-fashioned, inflexible TDM trunks. Now, three Cisco® experts show how to use Session Initiation Protocol (SIP) trunking to eliminate legacy interconnects and gain...

Internetworking with TCP/IP, Volume III describes the fundamental concepts of client-server computing used to build all distributed computing systems, and presents an in-depth guide to the Posix sockets standard utilized by Linux and other operating systems. Dr. Douglas E. Comer compares leading server designs, and describes the key tools and techniques used to build clients and servers, including Remote Procedure Call (RPC). The book contains examples of running programs that illustrate each ap...
