Embodiment Construction

[0043] see figure 1 and figure 2 , in an embodiment of the present invention, when a certain node in the wireless sensor network needs to perform task negotiation with other nodes, the steps are as follows:

[0044] Step 1. Before the task negotiation starts, the respective requirements and resources of the nodes in the wireless sensor network participating in the task negotiation are converted into value vectors of the Agent in the multi-issue space:

[0045] V → = v i k 1 , v i k 2 , Λ , v i k n > ;

[0046] In the above formula, Indicates the topic i k a valu...

Abstract

The invention relates to a task negotiation method of an HGA (hybrid genetic algorithm)-based wireless sensor network node. The method sequentially comprises the following steps of: 1, before the task negotiation begins, representing requests of a tenderer in the negotiation as an issue of ZA, and representing the resources of a bidder as an issue of TA; 2, after the task negotiation begins, generating a strategy generation offer according to the HGA by the TA, and then sending the strategy generation offer to the ZA; and 3, when sending and receiving processes finish, evaluating the received offer by the ZA according to an evaluation strategy and performing corresponding treatment according to the evaluation result. The method has the advantages that the task negotiation problem of the wireless sensor network node is converted into the negotiation problem of an Agent issue, and independent negotiation of the task is realized; 2, the negotiation result enables the utility sum of negotiating each node to be similar to the highest social benefits; 3, the negotiation efficiency is improved; and 4, the negotiation flexibility and finishing rate are improved.

Description

technical field [0001] The invention relates to the communication technology of wireless sensor network nodes, in particular to a wireless sensor network node task negotiation method based on HGA (Hybrid Genetic Algorithm). Background technique [0002] With the continuous development of wireless sensor network technology, its application fields are also expanding. It has expanded from the initial military field to other fields, and can accomplish things that traditional systems such as disaster warning and rescue, family health detection, and space exploration cannot accomplish. Task. Since wireless sensor networks generally seldom manage and intervene manually after deployment, this requires wireless sensor networks to be able to carry out autonomous task negotiation. Most of the devices in the wireless sensor network are wireless devices, and their network transmission capabilities, computing power, and power consumption have certain limitations. There is a strict time ...
