Optical wireless communication in sensor networks: data harvesting for disaster recovery operations - art. no. 67090C

Networks of sensors are an emerging technology for real-time data gathering in applications such as pollution monitoring, home security, surveillance, industrial control, etc. Many miniature nodes with sensing, computing and wireless communication capabilities are randomly deployed in an area or volume to be probed. One of the possible communication modalities for sensor networks is optical wireless communication (OWC). Initially, the sensor population must be mapped prior to interrogation by the base station and data communication from the sensor node. In this paper we review some theoretical and experimental work in this area and underline some of the challenges and possible solutions. The specific scenario of wireless sensor networks in a disaster recovery operation is modeled.
