  • Wireless ad hoc and sensor networks : theory and applications

    • Authors: Xiangyang Li (2008)

  • If you have to understand and optimize the performance of wireless ad hoc and sensor networks, this explanation provides you with the information and insights you need. It delivers an understanding of the underlying problems, and the techniques to develop efficient solutions and maximize network performance. Taking an algorithmic and theoretical approach, Li dissects key layers of a wireless network, from the physical and MAC layers (covering the IEEE 802.11 and 802.16 protocols, and protocols for wireless sensor networks and Bluetooth) through to the network routing layer. In doing so he reviews the practical protocols, formulates problems mathematically, solves them algorithmically and then analyses the performance. Graduate students, researchers and practitioners needing an overv...

  • UMTS signaling : UMTS interfaces, protocols, message flows and procedures analyzed and explained

    • Authors: Ralf Kreher (2007)

  • This completely revised and updated edition of the highly successful UMTS Signaling provides a deep insight into all aspects of UMTS signalling. The chapter structure has been reworked for improved "usability" for readers, as well as including many new features and updates. The successful trial, deployment, operation and troubleshooting of 3G or UMTS infrastructures and applications is the biggest challenge facing today's mobile communications. Network element instability, network element and multi-vendor interoperability, configuration and network planning faults are just a few of the challenges affecting performance and profitability that need to be addressed. This book is an invaluable guide to resolving such problems.

  • End-to-End Quality of Service Mechanisms in Next Generation Heterogeneous Networks

    • Authors: Abdelhamid Mellouk (2009)

  • This book presents and explains all the techniques in new generation networks which integrate efficient global control mechanisms in two directions: (1) maintain QoS requirements in order to maximize network resources utilization, and minimize operational costs on all the types of wired-wireless-mobile networks used to transport traffic, and (2) mix the QoS associated with home, access, and core networks in order to provide Quality of Service/Quality of Experience expected by users of new services. Communication between various devices makes it possible to provide unique and innovative services. Although ad hoc systems are very powerful mechanisms, they are also quite complex. This masterful resource demystifies these complexities with detailed accounts of the technologies, applicat...

  • Software architecture design patterns in Java

    • Authors: Partha Kuchana. (2004)

  • This book presents a detailed explanation of how to implement design patterns and develop software architectures by using patterns. It provides in-depth examples in Java and guides systems architects through the design process by answering when, why, and how to implement specific patterns. More than 40 examples in Java allow systems architects and developers to get their hands on implementing design patterns.

  • SPSS for intermediate statistics : use and interpretation

    • Authors: Nancy L. Leech (2005)

  • Designed to help students learn to analyze and interpret research data using intermediate statistics, this new edition features SPSS 12.0 for Windows, but can also be used with earlier versions. Each chapter introduces several related statistics and provides instructions on how to run them and interpret the outputs. The authors describe the use and interpretation of these statistics in user-friendly, non-technical language. The authors demonstrate how to choose the appropriate statistic based on the research design, how to use SPSS to answer research questions, and how to interpret and write about SPSS outputs. SPSS for Intermediate Statistics, 2/e provides unique learning tools.

  • User Interface Design for Programmers ‎

    • Authors: Joel Spolsky (2001)

  • Most programmers' fear of user interface (UI) programming comes from their fear of doing UI design. They think that UI design is like graphic designthe mysterious process by which creative, latte-drinking, all-black-wearing people produce cool-looking, artistic pieces. Most programmers see themselves as analytic, logical thinkers insteadstrong at reasoning, weak on artistic judgment, and incapable of doing UI design. In this brilliantly readable book, author Joel Spolsky proposes simple, logical rules that can be applied without any artistic talent to improve any user interface, from traditional GUI applications to websites to consumer electronics. Spolkys primary axiom, the importance of bringing the program model in line with the user model, is both rational and simple. In a fun a...
