Embodiment 1
[0047] Embodiment 1: as figure 1 As shown, a DV-Hop positioning algorithm based on sine-cosine optimization and segment-hopping optimization, first defines the concept of optimal anchor nodes, and selects the anchor node with the smallest average hop distance among all the anchor nodes around each unknown node as the optimal anchor node Then select any other anchor node and unknown node to form a triangle, and take the edge from the optimal anchor node to the unknown node as the optimal edge in the triangle; secondly, use the law of cosines to calculate the distance from the other anchor nodes to the unknown node to achieve the optimal jump distance The purpose; finally use the sine-cosine optimization algorithm (SCA) to improve the least squares method, and use the volatility of the sine-cosine function to find the optimal position of the unknown node.
