Problems solved by technology

[0003] For the cluster routing protocol of WSN, although it is better than the performance protocol of flat routing in many aspects, the cluster head in the clustering algorithm not only undertakes the task of data forwarding within the cluster, but also performs the data forwarding work with the base station, which is easy. Cause the energy consumption of the cluster head to die too quickly, thus shortening the life cycle of the network

Abstract

The invention relates to a wireless sensor network clustering routing method based on dual cluster head. The method comprises the following steps: a base station in a wireless sensor network sends an initialization message to the whole network; each node in the wireless sensor network reports a personal position, residual energy and node ID information to the base station; the base station acquires the position, the ID and the residual energy of the node in the wireless sensor network, and counts the total number of the node; the base station horizontally partitions a distribution region according to the counted information; a candidate main cluster head is elected according to the position, the ID and the residual energy of the node; different competitive radiuses are set according to a distance between the candidate main cluster head and the base station, a final main cluster head is elected in the competitive radius, and the final main cluster head is organized into a cluster. An intra-cluster transmission way and an inter-cluster transmission way are provided in data transmission. The technical scheme provided by the invention can solve the problem that the network survival period is short.

Description

technical field [0001] The invention belongs to the technical field of wireless sensors, and relates to a dual-cluster-head-based wireless sensor network cluster routing method. Background technique [0002] Wireless Sensor Networks (WSNs) is an ad hoc network composed of a large number of wireless sensors, which senses, collects and processes object information in the network coverage area in a cooperative manner, and transmits the collected data to target users. Since the energy of sensor nodes is limited, and it is not easy to replace the battery, how to reduce the energy consumption of nodes and prolong the survival time of the network has become a research hotspot in wireless sensor networks. The data transmission mode of the wireless sensor network is a many-to-one model, but due to the small communication distance of the nodes, the data needs to go through multi-hop routing to be transmitted and summarized to the base station. The sensor nodes close to the sink have ...
