A Routing Method for Wireless Sensor Networks Based on Dynamic Reachable Domains

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.
