Method for controlling hierarchical type route suitable for wireless sensor network

Abstract

The invention discloses a method for controlling a hierarchical type route suitable for a wireless sensor network. The method comprises the following steps of: 1) sensing and storing a distance of a network topology formed from wireless sensor nodes in a random arrangement; 2) based on an order N neighbor theory, when the position of the sensor nodes and the network topology are changed dynamically, determining the number of current optimal clusters kopt by analyzing the distribution dispersion and the curved transition of the nodes; 3) computing an occupation ratio of optimal cluster heads popt according to the number of the optimal clusters kopt, and selecting cluster aggregation by combining node residual energy; 4) introducing Hausdorff distance to adjust a cluster structure formed initially and quickly; and 5) transmitting data: transmitting data information acquired by each of the sensor nodes to a base station by using the cluster heads. The method has the advantages of providing correct computation for the optimal clusters, saving energy consumption of each of the nodes, realizing load balancing of the wireless sensor network, along with uniformly distributed cluster headsand reasonable cluster structure.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a layered routing control method suitable for wireless sensor networks. Background technique [0002] Wireless sensor networks are an emerging scientific field and an important part of today's Internet of Things. The wireless sensor network itself is a multi-hop self-organizing network composed of large-scale low-cost, low-power multifunctional micro-sensor nodes wirelessly, and belongs to the category of wireless networks. But different from the general wireless network, the wireless sensor network usually remains in a static state after the node is deployed, and the network topology will not change unless the node is damaged or dead; the network itself only cares about the sending and receiving of data, and the sender and receiver are not The focus of network concern. Therefore, the traditional routing mechanism based on IP protocol and the multi-hop routing for mobili...
