Abstract

The invention discloses a position-based uniform clustering hierarchical routing algorithm for a wireless sensor network, which comprises the following steps of: 1, carrying out regular hexagonal uniform clustering on a detection region, and carrying out layering on regular hexagonal clusters according to distances with a Sink node from a first layer to an mth layer until covering all sensor nodes; 2, in consideration of residual energy and network load factors, establishing a reasonable cluster head electing mechanism; 3, carrying out fusion on data in the clusters and carrying out pre-codingprocessing; 4, establishing a layer-by-layer route; and 5, carrying out data transmission and decryption. The position-based uniform clustering hierarchical routing algorithm disclosed by the invention has the beneficial effects that (1) the position-based uniform clustering hierarchical routing algorithm has high query directivity; (2) the position-based uniform clustering hierarchical routing algorithm is greatly improved in the aspect of prolonging the life cycle; (3) an more efficient, optimal and energy-saving routing link is established to transmit data; and (4) security of the data isensured.

Description

technical field [0001] The invention relates to a routing algorithm, in particular to a location-based uniform clustering hierarchical routing algorithm of a wireless sensor network, which belongs to the technical field of communication. Background technique [0002] Wireless sensor network (Wireless Sensor Network, WSN) is a multi-hop wireless sensor network formed by a large number of sensor nodes randomly distributed in the monitoring area in a self-organizing manner. Sensor nodes can perceive the surrounding environment, and have the functions of collecting data, information processing and fusion, and transmitting data over short distances. How to use limited resources to achieve efficient data collection and transmission is an important responsibility of WSN routing algorithms. [0003] There are various WSN routing algorithms. Studies have shown that, compared with flat routing algorithms, cluster head strategy and fusion technology in hierarchical routing algorithms ...
