Recent developments in low-power microelectronics and downsizing have led to the development and spread of wireless sensor networks. These networks can keep an eye on and adjust the ecosystem all by themselves. This chapter describes how WSNs and sensors fit into the larger picture of network design, and it contrasts WSNs with cellular networks and MANETs. To date, health problem diagnosis has only taken place at the server, not the actuator, for in-hospital or at-home patient monitoring. An effective routing mechanism and channel allocation at the MAC layer is required for data transmission from the sensor to the server. The U-healthcare application's algorithm paradigm and data collection model inform the routing protocol under consideration. This chapter describes the basic building blocks of a sensor network that can be used for virtually any purpose. Continuous monitoring of an environment or a patient's vital health parameters generates massive amounts of data. Since the server is outside of the sensor's 100-meter range and requires the use of the Wifi standard for sending real-time data streams, the use of this technology is a need. The use of WSNs in the U-healthcare sector is analysed and criticised. The chapter also includes discussion of the database management systems and microprocessor database support currently on the market. Complex operations on sensor data in the U-Healthcare domain are analysed in this study. Our research focuses on incorporating an outlier detection technique into a sensor device that routinely monitors blood sugar and blood pressure to ascertain whether or not the two together constitute a critical situation warranting an alert. Our research shows that a UDBMS has been built for deployment at the sensor, allowing for the dynamic creation and storage of databases as well as the execution of ad hoc queries at the sensor.
