Experimental studies on Wireless Sensor Networks

A wireless sensor network (WSN) is a computer network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions such as temperature sound vibration pressure motion or pollutants at different locations.[1] The development of wireless sensor networks was originally motivated by military applications such as battlefield surveillance. However wireless sensor networks are now used in many civilian application areas including environment and habitat monitoring healthcare applications home automation and traffic control etc.in this book we mainly focused Health care for elderly people by using multi sensor systems.
