Embodiment Construction

[0055] Such as figure 1 As shown, a computing task assignment method based on three-node cooperation in a wireless sensor network, the method includes the following sequential steps:

[0056] (1) Parameter setting for three-node collaborative computing;

[0057] (2) Determine the optimal task allocation of computing task bits among the three sensor nodes;

[0058] (3) Transmit computing tasks according to task assignment results, and execute computing tasks.

[0059] Described step (1) specifically refers to: as figure 2 As shown, in a wireless sensor network, there are multiple sensor nodes randomly distributed, and each sensor node is equipped with an antenna and has global channel state information. At a certain moment, a sensor node needs to perform an assignable computing task, and the The sensor node is named as the task node USER, the input bit size of the calculation task is L, and the delay constraint is T; the task node USER selects two nodes with the best surrou...

Abstract

The invention relates to a calculation task allocation method based on three-node cooperation in a wireless sensor network, comprising: setting parameters for three-node cooperation calculation; determining the optimal task allocation of the number of calculation task bits among three sensor nodes; according to the task allocation results Transfer computing tasks and execute computing tasks. Compared with the prior art, the present invention can complete calculation tasks with lower energy consumption under the premise of satisfying time delay constraints, and takes into account the channel conditions, calculation task size and time delay constraints in the sensor network; the present invention Encourage individual sensor nodes to share resources through collaborative computing to build a virtual resource pool, give full play to the computing power of sensor nodes, mobilize redundant resources in the network, and regard sensor nodes in the sensor network as a unified whole, considering the overall computing energy consumption and Communication energy consumption to design and optimize collaborative computing.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a calculation task allocation method based on three-node cooperation in a wireless sensor network. Background technique [0002] With mobile edge computing, mobile devices can transfer computing tasks to network edge devices equipped with computing capabilities, such as base stations and wireless access points, instead of completing computing tasks in the core network. This avoids delay fluctuations caused by remote transmission from mobile devices to cloud servers and reduces additional transmission energy. [0003] Advances in wireless transmission technology and embedded processors have enabled mobile edge computing to be applied to wireless sensor networks. It supports the execution of computing tasks on sensor nodes, which increases the response speed to user requests. A wireless sensor network is composed of a large number of small sensor nodes, which col...
