Abstract

The invention discloses a wireless body area network inter-interference mitigation method based on moving trajectory similarity, which comprises the following steps: modeling individual moving trajectories into a moving trajectory sequence to analyze the similarity of the moving trajectories among different wireless body area networks so as to obtain the probability of meeting and mutual interference among the wireless body area networks; and allocating a frequency hopping sequence to each wireless body area network according to the probability of meeting and mutual interference among the wireless body area networks so as to minimize interference conflicts in the network. According to the method, the socialized movement rule of individuals is fully analyzed, a corresponding solution is provided for the multi-WBAN coexistence interference problem in a centerless control scene, and the reliability of data transmission is greatly improved.

Description

technical field [0001] The invention relates to the field of electronic health, in particular to a method for mitigating interference between wireless body area networks based on similarity of moving trajectories. Background technique [0002] Wireless Body Area Network (WBAN) is a network composed of multiple wireless sensors, which has a wide range of applications in various fields of people's lives, such as electronic health, entertainment and sports. As a low-cost, convenient and efficient supporting technology for the health monitoring system for the elderly, wireless body area network can effectively alleviate the current situation of the shortage of social public medical resources. Nowadays, most of the wireless body area network technologies generally work in the Industrial Scientific Medical (ISM) frequency band commonly used in various countries. However, the number of mutually orthogonal channels in this frequency band is very limited, and different WBANs will hav...
