Routing Methods for Wireless Sensor Networks

Abstract

The invention relates to a wireless sensor network routing method comprising the steps that multiple forward nodes and aggregation nodes of a current node are acquired; first distance, second distance and third distance are acquired; a contour curve is generated according to the first distance, the second distance and the third distance; the expansion and contraction rate, the contour length and the contour curvature of the contour curve are calculated; internal force parameters based on the expansion and contraction rate and the contour curvature are calculated according to the contour length, and external force parameters based on the network performance parameters between the current node and the forward nodes are acquired; resultant force parameters are calculated according to the internal force parameters and the external force parameters; and the next hop node is determined according to the resultant force parameters. Selection of the next hop node is enabled to be more reasonable, unnecessary energy loss can be avoided, network congestion can be effectively avoided and the network performance is enabled to be better.

Description

technical field [0001] The invention relates to the technical field of wireless sensor network routing, in particular to a wireless sensor network routing method. Background technique [0002] The wireless sensor network is composed of sensor nodes with perceptual computing and communication capabilities. The nodes form a many-to-one communication network in a self-organizing manner, and send the collected data to the aggregation point through multi-hop. Since sensor nodes are mainly powered by batteries, the energy is limited and difficult to replenish. Therefore, saving and balancing the energy consumption of nodes and prolonging the network lifetime to the greatest extent are one of the main design goals of routing methods for wireless sensor networks. [0003] However, in some scenarios, such as electricity consumption information collection, transmission line detection, etc., nodes can be continuously powered by the line, and the energy is continuous. The previous rout...
