Recent advancements in Micro-Electro-Mechanical Systems have augmented research in Wireless Sensor Networks (WSN) capable of providing unprecedented high precision and high fidelity sensory data. Success of a deployed WSN largely depends on whether the network can provide desired sensory area coverage with acceptable network lifetime. This task becomes even more challenging if we consider the constraints of wireless sensor networks such as low processing power and bandwidth, limited memory and battery life, and short radio ranges. This book addresses the problem of area coverage...
