Route equalization method of multi-jump cooperative energy of body area network under condition of ensuring service quality

Abstract

The invention discloses a route equalization method of multi-jump cooperative energy of a body area network under the condition of ensuring service quality, comprising the following steps of: arranging a plurality of nodes on a human body; dividing the energy conditions of the nodes into a full grade, a fuller grade, a medium grade, a lower grade and an empty grade; dividing businesses generated by the nodes into a business grade with a high real-time requirement and a business grade with a low real-time requirement; when establishing a route, calculating the sum of energy consumed by other nodes in each path except for a source node and a target node and introducing energy factors in the calculating process; selecting a path with minimum sum of the consumed energy as a route for the businesses with lower real-time requirement, and selecting a path with least jumping number as a route for the businesses with higher real-time requirement; and also adopting a cooperative transmission method in a transmission process after establishing the route. The measures finally ensure that the energy of each node in the network is equally consumed, thereby ensuring the communication of the network and prolonging the survival period of the network.

Description

technical field [0001] The invention relates to the field of wireless body area networks, in particular to a body area network multi-hop cooperative energy balance routing method that guarantees service quality. Background technique [0002] In recent years, various portable wireless devices have emerged one after another, and people have shifted their attention to small human-centered networks, such as Personal Area Network, Home Area Network, and Vehicle Area Network. Network) and Body Area Network (BodyAreaNetwork) and other new network terms also appear. The miniaturization and intelligence of portable wireless personal devices have led to increasing research interest in wireless body area networks within the human body. [0003] Wireless Body Area Networks (WBAN) is an emerging technology developed in the medical and health field in recent years. It is mainly used in emergency rescue, telemedicine, home care and other occasions. Medical sensors are worn on the human b...
