Embodiment Construction

[0022] Such as figure 1 As shown, the wireless body area network resource allocation and task offloading algorithm for maximizing system revenue in the present invention includes:

[0023] Step 1: The wireless body area network generates multiple tasks with different priorities and data volumes at a certain moment, and each task calculates its value according to its own priority and data volume; the step 1 is specifically:

[0024] WBAN generates N tasks with different priorities and data volumes at a certain moment The value of the task, i.e. the reward for delivering benefits, can be expressed as follows:

[0025] R n =r×(1+K n ) 2 × log 2 (1+D n )

[0026] Among them, R n Indicates the value of the task, r indicates the unit task value constant, D n Indicates the data volume of the task, K n Indicates its priority and follows the wireless body area network priority specification of IEEE802.15.6.

[0027] Step 2: If the task can be processed locally, it will be d...

Abstract

The invention discloses a wireless body area network resource allocation and task unloading algorithm with maximum system revenue. The algorithm is based on a classic bargaining game model in the gametheory. An edge server for providing computing resources is used as a resource seller in the model; and the wireless body area network distributed in the service range of the server is used as a resource buyer, the two parties perform bargaining by taking maximization of own benefits as a target according to a selfish behavior mode in allusion to CPU resources and wireless channel resources, andfinally, an optimal resource allocation scheme and an optimal task unloading scheme of the whole system are obtained. The timeliness and reliability of wireless body area network data processing can be improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a wireless body area network resource allocation and task unloading algorithm for maximizing system revenue. Background technique [0002] Wireless Body Area Network (WBAN) is a human-centered wireless network composed of a central node and several sensor nodes attached to or implanted in the human body, used to monitor various physiological functions of the human body in real time. Data can effectively alleviate the medical problems caused by the shortage of medical resources and the unbalanced medical situation, and promote the development of electronic medical care. However, limited by the limited battery capacity and data processing capability of WBAN, how to provide users with services with long battery life, high data reliability and support for personalized customization is a challenge for WBAN-related research. [0003] At the same time, Mobile / Multi-access ...
