Wireless sensor network data acquisition method based on multi-hop routing and mobile elements

Abstract

The invention provides a wireless sensor network data acquisition method based on multi-hop routing and mobile elements. The method includes obtaining a network through wireless sensor nodes and a base station, by means of sensor node position determination and identifier determination, planing the mobile element walking routes, completing the information transmission between the wireless sensor nodes and the mobile elements, and allowing the mobile elements to transmit the information acquired during walking to the base station until the network dies. The method is adaptive to large scale, self organization, random arrangement, environment complexity and other characteristics of the wireless sensor network and can be arranged and used in a large amount in the field which is populated sparsely, the mobile elements and the traditional clustering algorithm are combined, the data can be transmitted effectively and accurately, the energy consumption of the sensor nodes is reduced, the topology structure changes while the nodes die, the cluster head node and the second level cluster head are re-selected, the energy consumption of the cluster head node is reduced to the utmost extent, and the total survive time of the network is prolonged.

Description

technical field [0001] The invention relates to the communication field, in particular to a routing method for a wireless sensor network. Background technique [0002] Wireless sensor network is a new generation of sensor network, which has a very broad application prospect. Its development and application will have a profound impact on various fields of human life and production. As early as the 1970s, the prototype of sensor network formed by using point-to-point transmission of traditional sensors and connecting sensor controllers appeared. We attribute it to the first generation sensor network. With the continuous development and progress of related disciplines, the sensor network also has the comprehensive processing ability to obtain a variety of information signals, and through the connection with the sensor controller, a sensor network with information synthesis and processing capabilities is formed. It is the second generation sensor network. Since the end of the ...

AI Technical Summary

Problems solved by technology

The traditional data collection method is completed through wireless communication between sensor nodes and network base stations, but it will lead to high energy consumption of sensor nodes and unbalanced energy consumption of nodes in the network, thereby reducing the normal working time of the network

In addition, traditional data collection methods require that the network must have connectivity

In order to ensure connectivity, a large number of sensor nodes need to be deployed in the network, which inevitably leads to node redundancy and increases network costs
