This book provides detailed descriptions of ZigBee® network protocols and supplies step-by-step instructions on how to set up and develop ZigBee-based customized applications. Starting with a brief introduction to near-field communications, low-power communications, and related protocols, it discusses ZigBee architectures, standards, and protocols. It also addresses potential issues such as power management, security, reliability, quality of service, topology control, MAC routing, and transport protocols. Emphasizing development tools based on readily available commercial kits, the book illustrates ZigBee applications across a range of fields.
