Embodiment Construction

[0069] During the monitoring of large-scale earthen sites in the field, the applicant established a multi-gateway wireless sensor network in order to understand the influence and law of natural differentiation and fission of large-scale sites in the field, and to grasp the situation of man-made ruins in a timely manner. Since the gateway cannot adopt wired power supply measures in the wild, the applicant uses solar and wind power to charge the gateway, thereby ensuring the power supply of the gateway. However, the amount of solar energy and wind energy charging is random, which causes the gateway to stop working due to insufficient power supply, which will cause large-scale data loss and retransmission of a large amount of data, thereby reducing the life cycle of the entire network. Aiming at the dynamic changes of network topology caused by gateways not being able to provide continuous power supply and random dormancy of sensing nodes, a wireless sensor network routing method ...

Abstract

The invention discloses a wireless sensing network route method based on multi-gateway data transmission. The method involves, through calculating work states of gateways, selecting a final target gateway and determining a final flow direction of a data flow, realizes data transmission from a current sending node to the final target gateway through opportunity transmission, reduces data packet concentration and vast packet loss which are caused by work failure of the gateways, and improves the correction transmission rate of data packets. Besides, the maintenance is stable, the cost is effectively reduced and controlled, and the network life cycle is prolonged.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a wireless sensor network routing method based on multi-gateway data transmission, and the method is applicable to a wireless sensor network for monitoring large-scale earthen sites in the field based on multi-gateway. Background technique [0002] Large-scale earthen sites are precious cultural heritages in my country. Due to human-made destruction and natural damage, their living conditions are worrying. It is urgent to carry out preventive protection by monitoring the living status of earthen sites, monitoring and regulating their living environment. However, due to the wide range of monitoring required for large-scale soil relics in the field, the complex environment, and the lack of basic network facilities, it poses new challenges to the design of the monitoring system. Wireless sensor network (WSN) meets the monitoring and protection needs of large-scale ...
