Abstract

The invention discloses a QoS-guaranteed MAC layer time slot allocation method in a body area network. The invention considers the delay cost and energy cost in the process of node transmission data, combines the node priority and the delivery probability of transmission to carry out an innovative design on the node utility function, and performs mathematical modeling on the optimization problem according to the definition of the utility function , give a time slot allocation scheme with lower complexity and better performance. Therefore, the time slot allocation scheme proposed by the present invention can improve the comprehensive utility of the network.

Description

technical field [0001] The invention relates to the technical field of wireless body area networks, in particular to a method for allocating time slots at the MAC layer for ensuring QoS in the body area network. Background technique [0002] Wireless body area network refers to a wireless sensor network that is centered on the human body and consists of local processing units (smart terminals such as mobile phones and bracelets) and wireless sensors distributed on the surface of the human body or in the human body. Usually, the local processing unit and common sensor nodes perform data transmission directly through single-hop communication, forming a star network. The sensor nodes collect the information of various parts of the human body, and then transmit it to the local processing unit for processing and display or further transmit it to the remote processing center. [0003] Due to the particularity of WBAN itself, the research on its communication protocol is facing so...
