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.
