Abstract

The invention discloses a wireless sensor network routing method based on a dynamic reachable domain. According to the wireless sensor network routing method based on the dynamic reachable domain, through utilization of the feature that nodes have a plurality of neighbor nodes, and the energy consumption is reduced by employing the farthest hop distance. Moreover, the residual energy of the nodes is taken into consideration, the priorities of the neighbor nodes are sorted according to the distance and the energy consumption, and the optimum nodes are selected for transmission. The nodes are in monitoring states, when the nodes are selected as relay nodes, transmission work is carried out. For the data relay problem in a one-dimensional (1-D) queue network, a routing algorithm based on the dynamic reachable domain is provided, thereby minimizing the energy consumption and maximizing the network service life. The distance among the nodes and the residual energy of the nodes are taken into consideration at the same time, and the nodes with relatively low energy are protected. A simulation result indicates that according to the algorithm based on the dynamic reachable domain provided by the invention, the network service life is prolonged well, and the network performance is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, in particular to a wireless sensor network routing method based on a dynamic reachable domain. Background technique [0002] At present, wireless sensor networks formed by a large number of sensor nodes through self-organization have been widely used in military perception, physical security, air traffic control, traffic monitoring, environmental monitoring and building structure monitoring and other fields. And with the continuous development of WSNs, low-energy, low-cost, multi-functional wireless sensor nodes have been gradually applied to high-efficiency wireless communication and electronics industries. In WSNs, the main task of the sensor nodes is to cooperatively monitor the environmental information in the area, collect and transmit data, and a large amount of energy will be consumed in the process of collecting and transmitting data. But thousands of physically embedded...
