Abstract

The invention discloses a multi-path routing method for a wireless sensor network, and belongs to the field of wireless sensor networks. The problems that in an existing routing method of the wireless sensor network, the density of nodes is not considered in the clustering process, consequently, network resource consumption is not uniform, and messages cannot be transmitted more efficiently are solved. According to the method, firstly, the density factor of the nodes is considered in the clustering process, and the phenomena that network resource consumption is not uniform and messages cannot be efficiently transmitted due to the fact that the number of the nodes in a certain cluster is too small are reduced. Secondly, the weights of the nodes in the cluster are ranked, and the number of the selected relay nodes is determined according to the weights of the nodes, so that resources in the network can be effectively utilized, and overflow of cache in the transmission process can be reduced while the submission rate of messages is ensured. The method is mainly used for realizing message transmission of the wireless sensor network.

Description

technical field [0001] The invention belongs to the field of wireless sensor networks. Background technique [0002] In recent years, with the continuous development of communication technology, the transmission mechanism has gradually shifted from wired communication to wireless communication. The emergence of wireless sensor networks has opened up a new dimension of transmission mechanism research. In wireless sensor networks, the interaction between sensor nodes depends on the communication between different types of sensors, such as pressure sensors, humidity sensors, and noise sensors. With the continuous evolution of sensing devices, sensors not only have powerful sensing capabilities and storage capabilities, but also have greatly improved their processing and communication capabilities. In the field of wireless sensor networks, efficient transmission mechanisms can effectively improve network performance. Therefore, how to design an efficient transmission mechanism...
