    Smart healthcare

    With the advent of the aging age of humanity, wearable medical sensors and their related smart medical networks have been widely applied. At present, there are more and more manufacturers producing wearable medical sensors. Due to the lack of adherence to unified standards, most sensor providers adopt their own standards. This system does not have plug and play medical functions at the bedside, which is a bottleneck in the development of wearable medical sensor networks.

    IoT services

    This system is an important component of future wireless ubiquitous networks (UCWW), mainly responsible for broadcasting, discovering, and using wireless business services (Advertisement, Delivery, Association). According to the standards of Next Generation Networks (NGNs), future wireless network services can be divided into wireless access services and wireless application services. With the significant increase in the number of wireless services, wireless ubiquitous service broadcasting systems need to use an independent channel for targeted delivery.
