Research of medical monitoring system based on WSN

A medical monitoring system based on wireless sensor network (WSN) is proposed in this paper. It designs cluster - tree wireless sensor network nodes, which consist of an acquisition module, a microprocessor unit and wireless communication module. The design makes it possible that the data is transmitted accurately from acquisition nodes to sink nodes through the router nodes, and the collection and transmission of wireless sensor network nodes are accurate and stable. It can greatly expand the capacity of monitor, improve the monitoring management, and increase monitoring efficiency. © Wang and Liu.
