specific Embodiment

[0087] The present invention proposes a fast and secure wake-up association mechanism based on body area network, so as to realize that the wireless body area network sensor nodes start to associate when they are safely awakened, shortening the time required from wake-up to MK establishment, and reducing the number of nodes During the waiting time, the association mode between the Hub and multiple nodes is designed; the nodes of the body area network in the present invention are all in a non-connected state.

[0088] When the Hub starts to establish a WBAN network or needs to communicate with nodes that are not in the Connected state, it will need to wake up the nodes. The wake-up operation is realized through the control type frame Wakeup and T-Poll, and the combination of the two methods can be used, or the T-Poll method can be used alone. It is stipulated in IEEE802.15.6 that nodes are awakened by Wakeup frames, and time slots are allocated by T-Poll for the exchange of Ass...

Abstract

The invention discloses a fast association wakeup method of a wireless body area network. The fast association wakeup method of the wireless body area network includes the steps that the frame head, the frame body and the frame tail of a wakeup frame are determined; a unicast wakeup association is adopted and comprises a brand new unicast wakeup frame and a unicast wakeup association mechanism; a multicast wakeup association comprises a multicast wakeup frame, an address index number comparison table and a multicast wakeup association mechanism. Through the method, the needed time from wakeup to MK establishment is shortened, the node awaiting time is shortened, and therefore the node energy loss is reduced to a certain extent, and the method can be used for the association wakeup process of sensing nodes in the wireless body area network.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for quickly waking up an association of a wireless body area network. Background technique [0002] Wireless Body Area Network (WBAN), that is, Wireless Body Area Network, can be regarded as a special application of Wireless Sensor Network (WSN), which refers to a wireless network composed of a series of wearable wireless sensor devices. WBAN will turn the human body into a part of the communication network, making people more and more dependent on wireless networks in daily life, thus realizing the ubiquity of the network in a true sense. [0003] The human body sensor network is mainly used for patient monitoring and physiological parameter measurement. The data measured by various sensors are transmitted to dedicated monitoring instruments or various communication devices through wireless network transmission. The important application of WBAN in m...
