This book provides a comprehensive introduction to the OMNeT++ simulation environment and an overview of its ecosystem of ever-growing frameworks, which provide simulation models for diverse communication systems, protocols, and standards. The book covers the most recent advances of the three key points in the OMNeT++ environment: (1) The latest features that are being added to OMNeT++ itself, including improvements in the visualization options, in data processing, etc. (2) A comprehensive description of the current state of development and the work in progress of the main simulation frameworks, covering several aspects of communication such as vehicular, cellular, and sensor networks. (3) The latest advances and novel developments coming from a large research community. The presentation is guided through use cases and examples, always keeping in mind the practical and research purposes of the simulation process. Includes an introduction to the OMNeT++ simulation framework and its main features; Gives a comprehensive overview of ongoing research topics that exploits OMNeT++ as the simulation environment; Provides examples and uses cases focusing on the practical aspects of simulation.

***2020 winner of the Christopher Bland Prize*** "Beautifully crafted and written, filled with darkness and light, compelling... She fights addiction with honesty and humour. And, like her, [we] come away changed forever." Yasmin Alibhai-Brown, RSL Christopher Bland Prize When Michele Kirsch's father is killed in a train crash, her mother gets the vapours and Michele gets extremely nervous. By her mid-teens, she has found salvation in valium. Her favourite words on the prescription sheet are "Take As Needed", which she interprets as Take All The Time. Later, as a wife and mother, she adds alcohol into the mix, and before long her life is spinning out of control. Leaving home "for the sake of the family", she takes the scenic route to rehab, redemption and reinvention. But this is no misery memoir. Clean is a darkly comic tale about the difficult choices we have to make as we navigate our lives. While working as a domestic cleaner in her 50s, Michele finds herself living vicariously through other people's messes, tidying her way through early sobriety. As the Duster of Large Things, she taps into her natural nosiness to reveal the absurdities of a seemingly banal job. This is a remarkable, powerful, and often unbearably funny story in which cleaning and getting clean lead to a strange and magical form of redemption.

This is a book about survival. How do companies survive when the basic conditions for their existence change overnight? The question has a newly revived and essential actuality as a result of the recent world economic crisis. The fall of the Berlin Wall on 9 November 1989 and the launch of the German Economic, Monetary and Social Union on 1 July 1990 radically changed economic conditions for more than 8,000 previously state-, municipal- or party-owned companies in the former German Democratic Republic (GDR). Overnight, most East German manufacturing plants had been devalued, after having been able to survive for decades thanks to a protected market in the East -- which also collapsed, along with the East German domestic market. For East German companies, the monetary union meant "the introduction of a social market economy without a market", as Birgit Breuel, president of the worlds largest holding company, the Treuhand agency, described it. In a move without historical precedent and under considerable political pressure, Treuhand privatised 15,000 companies and liquidated 4,000 others in less than five years. Many of these 15,000 companies did not survive. But for several hundred medium-sized and small businesses the market economy provided a real upturn, and for about one hundred companies it opened doors to previously unimaginable opportunities. Today, several of these firms are brand or market leaders in Germany or even globally. How did these companies succeed? For an answer, we visited 15 of these companies in about ten industries and evaluated the strategies they used to survive or, more importantly, become dominant players. What did they do differently from the companies that failed?
