Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] refer to Figure 1 ~ Figure 3 , a method for optimally deploying a radio frequency energy source for powering a body area network node, comprising the following steps:

[0039]Step 1. The body area network node is located on the user's body surface or in the body, and collects and communicates data by capturing the wireless signal energy sent by the surrounding radio frequency energy source. When a user moves in a certain area, there are generally several staying points with a long staying time and some relatively fixed moving trajectories. Therefore, based on the above characteristics, the user's mobility pattern is firstly modeled. According to the location information of multiple mobile users in a certain area within a certain period of time, the mobile model of group users is used as a set of frequent stay points V={v 1 ,v 2 ,...,v N} and the clustering...

Abstract

The invention discloses a radiofrequency energy source optimal deployment method for supplying energy to a body area network node. The method comprises the following steps: modeling a mobility pattern of a user into a graph constructed by residence points and track edges; and iteratively calculating the position of a new energy source in stages according to different target functions, wherein charging power of the body area network node on all residence points is higher than energy consumption power under the action of the new energy source in a first stage, maximum energy accumulated net consumption values of all track edges do not exceed an energy storage element capacity of the node under the action of the new energy source in a second stage, and an actual energy non-interruption probability of the body area network node meets a system requirement under the action of the new energy source in a third stage. The method is suitable for scenes in which the body area network node can be charged through capture of radiofrequency energy; the energy source can be deployed reasonably according to the mobility pattern of the user; an energy non-interruption requirement of a system is met; and the deployment cost is lowered.

Description

technical field [0001] The invention relates to a method for optimal deployment of a radio frequency energy source for supplying energy to nodes of a body area network, and the method is suitable for a body area network that captures radio frequency energy. Background technique [0002] With the development of wearable technology and wireless communication technology, smart sensing devices are increasingly used for human body monitoring. These devices capture various user data and upload them to the Internet cloud anytime and anywhere, becoming a new entrance to the Internet of Things. This kind of wireless network composed of body wearable sensors or biosensors implanted in the human body is called "body area network". Continuous physiological monitoring and early warning of diabetes and other patients. With the increasing popularity of implantable smart devices, the body area network will integrate with people and become an integral part of daily life. [0003] Tradition...
