Wireless sensor network (WSN) refers to a group of spatially dispersed and dedicated sensors for monitoring and recording the physical conditions of the environment and organizing the collected data at a central location. WSNs measure environmental conditions like temperature, sound, pollution levels, humidity, wind, and so on.

In the present book, twelve typical literatures about wireless sensor network published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on multidimensional scaling, data center monitoring, online collaborative sensor data management platforms, distributed sensor network, In-network processing and secure data aggregation, etc. We hope this book can demonstrate advances in wireless sensor network as well as give references to the researchers, students and other related people.
