Problems solved by technology

[0004] At present, the inter-network interference avoidance schemes based on the physical layer mainly include power control and frequency hopping schemes, while the schemes based on the MAC layer mainly include distributed or centralized inter-network networking schemes. Most of these schemes have interference avoidance mechanisms and the effect is not ideal. , limited number of wireless body area networks, heavy load, etc.

Abstract

The embodiment of the invention discloses an internetwork interference avoiding method based on a nested composite superframe structure. The method comprises the nested composite superframe structure, improved frame structures and a communication mechanism under the composite superframe. In adoption of the embodiment of the invention, the internetwork interference can be effectively avoided; and performances such as the packet loss probability and the throughput capacity can be improved.

Description

technical field [0001] The invention relates to the communication field, in particular to an inter-network interference avoidance method based on a nested composite superframe structure. Background technique [0002] In China, which has a large population base and increasingly serious aging, the human and material resources used for medical care are increasingly in short supply, and there is an urgent need to study new methods to solve the health monitoring problem of the elderly. The human body-centered wireless body area network monitors the physiological indicators of the human body in real time by the sensors deployed in the body and on the body surface, and wirelessly transmits them to the remote terminal for processing through the coordinator in the network, avoiding the impact of the connection between the devices on the patient's activities. It is the best solution for geriatric diseases such as hypertension and diabetes. In addition, it can also meet people's needs...
