基于云边协同和用户偏好的无线体域网通信与计算资源分配研究

The popularity of Wireless Body Area Networks (WBANs) is restricted by the limited network resources and the storage and computing capability of intelligent devices. Cloud computing and edge computing are urgently needed to meet the needs of mass health data with low-latency, low-power consumption, high-reliability and user personalized service requirements. The proposal integrates network communication and computing resources, studies the cloud-edge collaborative WBAN resource scheduling problem, aiming to reduce network overhead, improve resource utilization and improve user satisfaction. The research is carried out from the following three aspects: (1) Design a multi-attribute decision making based computation offloading strategy, facilitating load balancing and resource allocation; (2) Propose a communication and computing collaborative resource allocation scheme, and further perform multi-objective optimization to minimize delay and energy consumption; (3) Establish a resource demand prediction model based on mobile users' temporal behavior, and design a cross-layer handoff management pattern to enhance service continuity and user experience. The research results can not only promote the reliability, availability and flexibility of WBAN, but also provide strong theoretical support and technical support for the development of intelligent healthcare.
