Highlights
In this content, wireless sensor network (WSN) is a hot issue and new trend of ubiquitous computing technologies to implement the ubiquitous society
WSNs are expected to be applied in many long-term applications such as scientific exploration, preventive maintenance, disaster management, emergency management, security and surveillance, environmental monitoring, monitoring in domestic situations, civil, biological, a wide range of military, and health-care applications, and infrastructure protection
WSNs are composed of a collection of many sensor nodes that are deployed in a sensor field, each of which collects data and relays them to the base station where data can be analyzed, applied, and used efficiently
Summary
Wireless sensor network (WSN) is a hot issue and new trend of ubiquitous computing technologies to implement the ubiquitous society. These applications require efficient and flexible sensor networks [4]. WSNs are composed of a collection of many sensor nodes that are deployed in a sensor field, each of which collects data and relays them to the base station (called a sink node) where data can be analyzed, applied, and used efficiently. A sensor node is made of a sensing device, a processing unit, a transceiver, and a power unit.
