7360 results about "Wireless sensor networking" patented technology

A wireless sensor network is a group of specialized transducer s with a communications infrastructure for monitoring and recording conditions at diverse locations. Commonly monitored parameters are temperature, humidity, pressure, wind direction and speed, illumination intensity, vibration intensity, sound intensity, power-line voltage, chemical concentrations, pollutant levels and vital body functions.

Energy efficient wireless sensor network routing method

The invention discloses a routing method for the wireless sensor network with efficient energy, which is suitable for the layered sensor network structure. The routing method is composed of initialization, cluster building, adjacent clusters routing and routing maintenance, wherein, an initialization process of the protocol makes a Sink node obtain a topology and network average energy of the sensor network, and each node obtains hop counts from the node to the Sink node; in the stage of the cluster building, a repeated division method is used to divide sensor network clusters, the divided clusters are even, and a leader cluster node is undertaken by nodes with higher residual energy; the adjacent clusters routing uses an ant colony algorithm to determine the probability of using a link to send information according to the link pheromone concentration, and the link pheromone concentration is increased with the information transmission on the link and is reduced with the time going; and the routing maintenance stage is responsible for updating link pheromone concentration, and makes the nodes inside the cluster with higher residual energy undertake the leader cluster in turn. The routing method can reduce the consumption of the network total energy, can balance the consumption of the node energy and can prolong the network life cycle.

Method for realizing medical and healthy care system based on Internet of things

The invention discloses a method for realizing a medical and healthy care system based on the Internet of things, which consists of five parts, namely a medical sensing node, a wireless sensor network gateway, mobile terminal equipment, system software and terminal software. The medical sensing node acquires pathological information of a human body, such as blood oxygen, sphygmus, pulse and body temperature, by various probes, such as a blood oxygen probe, a pulse probe and a body temperature probe and then transmits data to wireless sensor network gateway equipment through a wireless sensing module; and the gateway equipment transmits pathological data to terminal equipment through an infrastructure network by implementing seamless switching among the wireless sensing network, an Ethernet and a wireless local area network to get rid of the restrict of wireline equipment and use related mobile equipment, such as a PDA and a smart phone, to monitor the pathological information of a patient conveniently and fast, in a hospital or a wireless network coverage. The system can be applied to daily life and work of people actually so that a medical personnel and a patient family member can conveniently and fast monitor the pathological information of the wirelessly and remotely.
