In this thesis, we explore new techniques for robust, efficient, loop-free on-demand routing in Mobile Ad hoc Networks (MANETs) using the same information (i.e., topology information, sequence numbers, etc.,) used in prior on-demand routing protocol proposals. We provide new insights into the robustness of protocols based on destination-sequence numbers when operating with node failures and loss of routing information, and present a new destination-sequence number framework that works correctly even with failure conditions. We also show how destination-sequence numbers can be manipulated as routing labels for improving performance, rather than being strictly treated as time-stamps. We present two different routing approaches that exploit the topology information that can be collected on-demand during the route request ood search. The first approach translates topology information into labels that are then stored at nodes in strict lexicographic ordering along any successor path to a destination. Loop-freedom is maintained by allowing nodes to only pick "smaller" labels. The second approach maintains a list of topology information that should not be trusted in-addition to the known path to a destination. Using the notion of trusted topology, nodes can always make routingWe conclude our research with a new on-demand routing technique that exploits the route request search process, which is an integral part of any on-demand routing protocol. Without requiring any additional mechanisms or information, we use the uniqueness of route requests to realize a on-demand routing framework. We, then, present extensions to the basic framework to improve performance using more information that can be collected during the flood search process.

Welcome to Zhangjiajie for the 3rd International Conference on Computer Network and Mobile Computing (ICCNMC 2005). We are currently witnessing a proliferation in mobile/wireless technologies and applications. However, these new technologies have ushered in unprecedented challenges for the research community across the range of networking, mobile computing, network security and wireless web applications, and optical network topics. ICCNMC 2005 was sponsored by the China Computer Federation, in cooperation with the Institute for Electrical and Electronics Engineers (IEEE) Computer Society. The objective of this conference was to address and capture highly innovative and stateof-the-art research and work in the networks and mobile computing industries. ICCNMC 2005 allowed sharing of the underlying theories and applications, and the establishment of new and long-term collaborative channels aimed at developing innovative concepts and solutions geared to future markets. The highly positive response to ICCNMC 2001 and ICCNMC 2003, held in Beijing and Shanghai, respectively, encouraged us to continue this international event. In its third year, ICCNMC 2005 continued to provide a forum for researchers, professionals, and industrial practitioners from around the world to report on new advances in computer network and mobile computing, as well as to identify issues and directions for research and development in the new era of evolving technologies.

The structure that anchors Chicago Every day Chicagoans rely on the loop of elevated train tracks to get to their jobs, classrooms, or homes in the city’s downtown. But how much do they know about the single most important structure in the history of the Windy City? In engagingly brisk prose, Patrick T. Reardon unfolds the fascinating story about how Chicago’s elevated Loop was built, gave its name to the downtown, helped unify the city, saved the city’s economy, and was itself saved from destruction in the 1970s. This unique volume combines urban history, biography, engineering, architecture, transportation, culture, and politics to explore the elevated Loop’s impact on the city’s development and economy and on the way Chicagoans see themselves. The Loop rooted Chicago’s downtown in a way unknown in other cities, and it protected that area—and the city itself—from the full effects of suburbanization during the second half of the twentieth century. Masses of data underlie new insights into what has made Chicago’s downtown, and the city as a whole, tick. The Loop features a cast of colorful Chicagoans, such as legendary lawyer Clarence Darrow, poet Edgar Lee Masters, mayor Richard J. Daley, and the notorious Gray Wolves of the Chicago City Council. Charles T. Yerkes, an often-demonized figure, is shown as a visionary urban planner, and engineer John Alexander Low Waddell, a world-renowned bridge creator, is introduced to Chicagoans as the designer of their urban railway. This fascinating exploration of how one human-built structure reshaped the social and economic landscape of Chicago is the definitive book on Chicago’s elevated Loop.

The International Conference on Networking (ICN01) is the first conference in its series aimed at stimulating technical exchange in the emerging and important field of networking. On behalf of the International Advisory Committee, it is our great pleasure to welcome you to the International Conference on Networking. Integration of fixed and portable wirele ss access into IP and ATM networks presents a cost effective and eff icient way to provide seamless end to end connectivity and ubiquitous access in a market where demands on Mobile and Cellular Networks have grown rapidly and predicted to generate billions of dollars in revenue. The deployment of broadband IP based technologies over Dense Wavelength Division Multiplexing (DWDM) and integration of IP with broadband wireless access networks (BWANs) are becoming increasingly important. In addition, fixed core IP/ATM networks are constructed with recent move to IP/MPLS over DWDM. More over, mobility introduces further challenges in the area that have neither been fully understood nor resolved in the preceding network generation. This first Conference ICN01 has been very well perceived by the International networking community. A total of 300 papers from 39 countries were submitted, from which 168 have been accepted. Each paper has been reviewed by several members of the scientific Program Committee.

Tuning and Control Loop Performance, Fourth Edition provides the knowledge to eliminate the misunderstandings, realize the difference between theoretical and industrial application of PID control, address practical difficulties, improve field automation system design, use the latest PID features, and ultimately get the best tuning settings that enables the PID to achieve its full potential. The proportional-integral-derivative (PID) controller is the heart of every control system in the process industry. Given the proper setup and tuning, the PID has proven to have the capability and flexibility needed to meet nearly all of industry’s basic control requirements. However, the information to support the best use of these features has fallen behind the progress of improved functionality. Additionally, there is considerable disagreement on the tuning rules that largely stems from a misunderstanding of how tuning rules have evolved and the lack of recognition of the effect of automation system dynamics and the incredible spectrum of process responses, disturbances, and performance objectives.
