Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, the entire wireless energy communication network includes: a plurality of common sensor nodes, a plurality of hybrid access points, and the common sensor nodes and the hybrid access points are evenly arranged to form the entire wireless energy communication network. Among them, the hybrid access point obtains renewable resources and is equipped with a wireless energy transmitter to control the transmission of energy packets by adjusting the antenna angle and transmission time. At the same time, the hybrid access point also has the function of a base station node. It collects information collected by each node in the network, summarizes it and then reports it to the user. It is a terminal for information release and aggregation.

[0030] A large number of ordinary sensor nodes are randomly arranged in the network area. These nodes are ...

Abstract

The invention discloses a sleep scheduling method under a wireless power communication network. Common sensor nodes have two states of sleep and activation and the two states can switch between each other in order. When a sum of the obtained power and the remaining battery power is not sufficient to supply the upcoming of the power consumption, the nodes will enter the sleep state, and in the period, there is no need to collect and upload data; the remaining power is provided for the nodes and a CKN algorithm will be carried out, a suitable K value is set, part of the node sleep part is activated, the activated nodes will carry out work of data monitoring and transmission, and finally the data is uploaded to a base station. In the process, when the power received by all the nodes is surplus, the surplus power can be converted and stored in batteries to be provided for node consumption the next time. According to the sleep scheduling method under the wireless power communication network, renewable energy is used as a power acquirement source, the network operation is maintained by modes of wireless power emitting and storage, the time distribution rates of wireless power transmission and data transmission are regulated, and the best power utilization ratio is determined.

Description

technical field [0001] The invention relates to a sleep scheduling method under a wireless energy communication network, and belongs to the technical field of sleep scheduling of communication equipment. Background technique [0002] Industrial wireless sensor networks (IWSNs) are gradually being applied to all walks of life. Due to the low price, small size and convenience of sensor nodes, it is difficult to deploy conventional wired sensor networks in industrial environments due to too many hidden places in buildings and environmental obstacles. It is undoubtedly the best choice. Use wireless devices to self-organize to form a network to detect the status of complex environments. The emergence of wireless sensing technology has attracted worldwide attention and is known as one of the most influential technologies in the 21st century. [0003] However, the insufficient energy of wireless devices has become an important factor limiting its development. Wireless sensor node...
