Embodiment Construction

[0031] In order to explain the technical solution of the present application more clearly and verify its effect through experiments, the specific methods and test results are described below: Step (1) Start from the original (source) node, and establish a decision-making solution for the communicable nodes around the current node. Decision-making options are the content of the decision-making process. In the decision-making process, if a certain plan can be realized, or the plan meets the requirements of the decision-maker, then such a plan is a decision-making plan. Generally speaking, the number of decision-making plans is not unlimited. The target value and result of the traditional decision-making scheme are definite, but they can be uncertain numbers in the technical scheme. In the technical scheme corresponding to the present application, it is possible to realize a routing mode from the origin through any node around, and this mode is a decision-making scheme; step (2) ...

Abstract

The invention discloses a wireless sensor routing algorithm based on the fuzzy multi-attribute decision. The method comprises the following steps that (1) communicable nodes around the current node are created as decision schemes by starting from a source node; (2) the fuzzy attributes of the decision schemes in the step (1) are determined, and a fuzzy evaluation matrix X is established; (3) standardized processing is performed according to the fuzzy evaluation matrix so that a standardized fuzzy decision matrix H is obtained and the objective weight is determined by using the H; and the subjective weight is determined according to the preference in the fuzzy evaluation matrix; (4) the combination weight is determined by using the objective weight and the subjective weight of the previous step; (5) the combination weight is combined with the fuzzy decision matrix so as to calculate a comprehensive evaluation value, the optimal point is selected to act as a next jump node and set as the current node; and (6) whether the node belongs to a sink node is judged, and the algorithm is ended if the node belongs to the sink node; or the process returns to the step (1) for repetition if the node does not belong to the sink node. According to the technical scheme, the more stable, reliable, scientific and objective fuzzy multi-attribute wireless sensor routing algorithm can be obtained.
