Embodiment Construction

[0020] It is easy to understand that, according to the technical solution of the present invention, those skilled in the art can imagine various implementations of the present invention for transmitting information in a wireless sensor network without changing the essence of the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the entirety of the present invention or as a limitation or limitation on the technical solution of the present invention.

[0021] combine figure 1 , the wireless sensor network includes wireless sensors represented by dots. Assume that the sensing area of ​​the wireless sensor network is a rectangular area, and three mobile aggregation nodes S1, S2, and S3 represented by triangles are deployed in the sensing area. The mobile aggregation node is regarded as a cluster head node, thus forming three clusters centere...

Abstract

The invention proposes an energy-efficient routing protocol based on multiple mobile convergence nodes. Deploy multiple mobile aggregation nodes in the sensing area of ​​the wireless sensor network, and use each mobile aggregation node as a cluster head to form multiple clusters; each mobile aggregation node can move autonomously and communicate with each other; The current sensor node first determines the distance between itself and the mobile sink node, if the distance is less than its transmission radius, then the current sensor node communicates directly with the mobile sink node; otherwise, calculates the distance from the current sensor node to the mobile sink node The maximum optimal hop number and the maximum distance to the next-hop sensor node are used to find the best next-hop sensor node. The invention avoids the defects of energy void phenomenon and uneven distribution of cluster heads, reduces network traffic load, and greatly prolongs the life cycle of the wireless sensor network.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and in particular relates to a method for transmitting data in a wireless sensor network. Background technique [0002] A wireless sensor network is usually composed of a large number of small and low-cost sensors, and the sensor nodes send the collected information to the sink node through a single-hop or multi-hop mode. These sensor nodes themselves have computing power, storage capacity and communication capacity. Since WSN does not need the support of fixed network infrastructure, it has the advantages of easy rapid deployment, easy expansion, strong resistance to destruction, and suitable for harsh environments. Many fields have important research significance and broad application prospects. [0003] Due to the small size of the sensor nodes, the calculation, storage and communication capabilities of the nodes are limited; in particular, the sensor nodes are generally pow...
