This book provides the basics needed to develop sensor network software and supplements it with many case studies covering network applications. It also examines how to develop onboard applications on individual sensors, how to interconnect these sensors, and how to form networks of sensors. Included is actual code tested in a laboratory environment, as well as structured examples that allow demonstration of material with only a small network of four (or more) sensor nodes and a laptop. Professionals working in industry, graduate students, computer science professionals, and academic researchers will benefit from this resource.
