Congestion affects the performance of a wireless sensor network in two aspects: increased data loss and reduced lifetime. All data generated in wireless sensor networks may not be alike; some data may be more important than others and hence may have different delivery requirements. As deployment sizes and data rates grow, congestion arises as a major problem in these networks. This congestion leads to indiscriminate dropping of data, i.e. data of high importance might be dropped while others of less importance are delivered. In this Book, I take a look at data delivery issues in the presence of Congestion Aware Routing Protocol designed earlier for wireless sensor networks. I propose a new data prioritization and a priority aware routing protocol - Advanced Congestion Aware Routing (ACAR) which slacking the packet dropping rate of data packets.
После успеха двух синглов ("Djon maya ma?" (feat. Victor D?m?) и "All in You" (feat. Anna Kova)) дуэт французских электронных диджеев и продюссеров Synapson выпускают свой дебютный альбом под названием Convergence. Оба сингла входили в топ-10 французского чарта и альбом обещает стать заметным событием для всех любителей европейской электронно-танцевальной музыки.
In real world wireless sensor network applications, data gathering is an major issue,by means of data gathering increase the network life time.This means minimum energy should be consumed and transmission should occur with minimum delay which are conflicting requirements. Energy and delay are the major parameter for lifetime of any wireless sensor network.Efficient data gathering reduces the number of data transmission and consume less power.
There is today a pronounced and accelerated convergence in architecture. This convergence is occurring by doers not thinkers; in practice not academia; in building design, fabrication, and construction. It is about solution-centric individuals engaged in real time problem solving, not in abstractions. The nature of this convergence, where things are converging and what that means for architecture, is the subject of this book. – from the Introduction Those working in architecture and engineering feel pressure to work faster, at lower cost, while maintaining a high level of innovation and quality. At the same time, emergent tools and processes make this possible. Convergence is about the firms, teams and people who thrive in this environment as a result of their ability to creatively combine and innovate. It seeks to answer several timely questions: What are the tools and work processes that are converging? How are individuals and organizations converging their tools and work processes? What challenges and benefits are they seeing? What is the ultimate endgame of this convergence? What skillsets and mindsets would someone need to develop to work effectively in this changing environment? What are the implications of convergence on the role of the designer, and on design? On how we design, build, fabricate, and construct? On how we work? The book explains how convergence relates to, but ultimately differs from integration, consolidation, multi-tasking, automation, and other forms of optimization. The practice-based research builds upon the author's research in BIM and in the collaborative leveraging of data in design and fabrication. As an investigation and meditation on the impact of technology on the education and making of design professionals Convergence explains what is happening in the world of design, and discusses the implications for the future of education, training and practice.

This book deals with the issue of convergence in efficiency levels among Indian public sector banks (PSBs) during the post-reforms. To accomplish the task of measuring technical efficiency for individual PSBs, we have used the increasing popular methodology of Data Envelopment Analysis. Further, we have utilized the traditional cross-sectional regression approach for investigating the presence of sigma- and beta-convergence in efficiency levels of PSBs. The empirical results indicate that the majority of PSBs have observed an ascent in technical efficiency during the post-reforms years. Further, the study confirms a presence of convergence phenomenon in the Indian public sector banking industry. This book will be useful for the research scholars intending to work on the efficiency and productivity analysis.
