The wireless medium is a shared resource. If nearby devices transmit at the same time, their signals interfere, resulting in a collision. In traditional networks, collisions cause the loss of the transmitted information. For this reason, wireless networks have been designed with the assumption that interference is intrinsically harmful and must be avoided. This book, a revised version of the author's award-winning Ph.D. dissertation, takes an alternate approach: Instead of viewing interference as an inherently counterproductive phenomenon that should to be avoided, we design practical systems that transform interference into a harmless, and even a beneficial phenomenon. To achieve this goal, we consider how wireless signals interact when they interfere, and use this understanding in our system designs. Specifically, when interference occurs, the signals get mixed on the wireless medium. By understanding the parameters of this mixing, we can invert the mixing and decode the interfered packets; thus, making interference harmless. Furthermore, we can control this mixing process to create strategic interference that allow decodability at a particular receiver of interest, but prevent decodability at unintended receivers and adversaries. Hence, we can transform interference into a beneficial phenomenon that provides security. Building on this approach, we make four main contributions: We present the first WiFi receiver that can successfully reconstruct the transmitted information in the presence of packet collisions. Next, we introduce a WiFi receiver design that can decode in the presence of high-power cross-technology interference from devices like baby monitors, cordless phones, microwave ovens, or even unknown technologies. We then show how we can harness interference to improve security. In particular, we develop the first system that secures an insecure medical implant without any modification to the implant itself. Finally, we present a solution that establishes secure connections between any two WiFi devices, without having users enter passwords or use pre-shared secret keys.

Voice over Internet Protocol (VoIP) networks have freed users from the tyranny of big telecom, allowing people to make phone calls over the Internet at very low or no cost. But while VoIP is easy and cheap, it's notoriously lacking in security. With minimal effort, hackers can eavesdrop on conversations, disrupt phone calls, change caller IDs, insert unwanted audio into existing phone calls, and access sensitive information. Hacking VoIP takes a dual approach to VoIP security, explaining its many security holes to hackers and administrators. If you're serious about security, and you either use or administer VoIP, you should know where VoIP's biggest weaknesses lie and how to shore up your security. And if your intellectual curiosity is leading you to explore the boundaries of VoIP, Hacking VoIP is your map and guidebook. Hacking VoIP will introduce you to every aspect of VoIP security, both in home and enterprise implementations. You'll learn about popular security assessment tools, t

Sensor motes are small devices with sensing, computing and wireless communication capabilities. Such devices form a Wireless Sensor Network (WSN) which can be used for many applications like gathering of environmental data and even monitoring enemy activity on a battlefield. In order to achieve this efficient ad-hoc routing protocols must be used. Such routing protocols are of prime research interest. There exist many different approaches most of which are studied through simulation only. At the same time real hardware platforms for this research become widely available and affordable. In this book a real world environmental monitoring task is taken and a complete WSN application for this task is developed. As hardware platform Crossbow Technology's Cricket motes are used. They are programmed using TinyOS operating system and the NesC language. The usability of various state-of-the-art routing mechanisms for the specific application is discussed. Finally some of these are selected and implemented for use in the developed WSN application. The performance of the different available routing protocols is then measured and compared through actual deployment of the WSN.

MPLS is many things to many people. If you’re moving IP voice traffic, it may mean performance gains for you.

Daniel Minoli’s Voice Over MPLS gives you the technical and business lowdown on innovative new solutions for packet-based voice. What does it take to build flexible, high-performance networks with enhanced quality of service? Maybe not as much as you think.

RELIABLE VOICE SERVICES THAT CUSTOMERS CAN AFFORD

With VoMPLS, you can deliver the quality associated with VoIP over ATM links without the cost in either bandwidth or equipment. Based on label-switching standards from the IETF and the work of a number of leading companies, Voice over MPLS lets you packetize voice without the added overhead of IP encapsulation. It also suppresses periods of silence, freeing up bandwidth for other uses.

From one of the most experienced names in telecom technology, Voice Over MPLS shows you how to—
* Provide multiple, high-quality services without costly leased lines
* Deliver low-bandwidth voice over ATM, Frame Relay, or IP
* Add phone “lines” without adding equipment
* Solve scaling issues for small- and medium-sized users
* Obtain consistent call quality without crunching bandwidth
* Discover ways to protect revenues during deployment
* Evaluate the potential role of VoMPLS in big-picture convergence
* Evaluate VoMPLS’s impact on public networks

Find the engineering details you need for Label Switched Paths (LSPs), layers, signaling, CoS (Classes of Service), QoS (Quality of Service), VoMPLS in VPNs (Virtual Private Networks), implementation options, deployment, and more.

Bypassing the old circuit-switched hardware, softswitches streamline message traffic and provide a much more efficient service development environment. Along with SIP, this technology leverages Internet technologies to replace plain-old-telephone service. Developers who are freed up by softswitch technology to build cost-effective 3G serives will learn how it works and what applications it can support. Network managers making hard decisions about whether to deploy VoIP will learn pros and cons, costs and benefits, and most importantly how to separate myth from reality.

OSI IN THE VOICE ENVIRONMENT

HERE’S STRAIGHTFORWARD EXPLANATIONS OF THE OSI LAYERS AND THEIR RELATIONSHIP TO TELECOM SERVICE AND EQUIPMENT. WHETHER YOU NEED ANWERS ON HARDWARE, SOFTWARE, ERROR CONTROL OR INTERFACES, LOOK INSIDE FOR BASIC FACTS AND HOW TO MANAGE THOSE CRITICAL “SPECIAL CIRCUMSTANCES”

The OSI (Open System Interconnection) Reference Model is a cornerstone of modern network design. Although the OSI model has become almost synonymous with data communications, it serves the public switched telephone network (PSTN) as well and is a productive way to organize and teach the building blocks of telecom systems.

In OSI Reference Model for Telecommunications, hands-on expert Debbra Wetteroth provides telecom staffers the information they need to gain a working knowledge of this essential telecom service architecture and equipment. Her style that breaks down the barriers between data and voice vocabularies. This quick reference to the OSI model puts the data you need everyday at your fingertips.

Look inside for an understandable schematics of:

* Mapping PSTN functions to OSI

* The basics of successful data transmissions

* What OSI is and does

* The components that make up OSI

* OSI “common knowledge” (the kind that’s not always so common), such as numbering system, signaling rates, and noise distortion data

* A detailed description of Layers 1 to 3 and a thorough review of the Transport Layer. For each layer, you’ll learn roles, functions, definitions, and more

This unique volume will prove invaluable to telecommunications technicians, field supervisors, switch managers, network analysts, network designers, and anyone else who needs detailed explanation of the many components of OSI.

Service and Device Discovery is a complete survey of the state-of-the-art in an emerging field. Client/server architectures may not be new, but the world has changed around them. Increasingly complex networked environments and the proliferation of mobile devices create many instances where highly dynamic client/service behavior is the norm and not the exception. Service discovery protocols enable plug and play architectures, where services may be introduced into a network and removed at will, without configuration hassles. In addition, service discovery is an important step toward eliminating manually installed drivers, relying instead on standard interfaces to put devices in touch.

WHY SERVICE DISCOVERY?

Service discovery will make networked devices significantly less tedious to deploy and use than they are today. As a way to standardize the environments in which client/server applications are developed and used, service discovery technologies have the potential to:
* make interactions between clients and services much more dynamic
* provide software tools for developing machine-to-machine communications
* automate discovery of required services and peripherals
* reduce administrative overhead for deploying or interfacing services
* minimize re-configuration and encourage more device mobility
* build more interesting applications for networked environments

INSIDE THE SERVICE DISCOVERY FRAMEWORK, designers and programmers will learn how clients can discover needed services. How services advertise their presence. How catalogs track available services and garbage collection facilities rid the system of outdated information. How multicast is used to support discovery and advertisement. How to enable clients to browse and subtype services. And how to anticipate interoperability issues.

In this book, researcher and developer Golden G. Richard III:
* Condenses thousands of pages of protocol specifications to their essentials and helps you interpret predictably terse material
* Investigates all four leading protocols for service discovery
* Provides complete client and service examples in Java and C

Service and Device Discovery: Protocols and Programming contains fully documented source code for representative clients and services, for all four technologies, examined and explained in detail.
