Optimal coverage in wireless sensor networks This book will serve as a reference presenting state of the art research on theoretical aspects of optimal sensor coverage problems. Readers will find it a useful tool for furthering developments on theory and applications of optimal coverage; much of the content can serve as material for advanced topics courses at the graduate level. The book is well versed with the hottest research topics such as Lifetime of Coverage Weighted Sensor Cover k Coverage Heterogeneous Sensors Barrier Sweep and Partial Coverage Mobile Sensors Camera Sensors and Energy Harvesting Sensors and more. Topics are introduced in a natural order from simple covers to connected covers to the lifetime problem. Later the book begins revisiting earlier problems ranging from the introduction of weights to coverage by k sensors and partial coverage and from sensor heterogeneity to novel problems such as the barrier coverage problem. The book ends with coverage of mobile sensors camera sensors energy harvesting sensors underwater sensors and crowdsensing. Preface 1. Introduction 2. Sensor Cover 3.
