A method and apparatus for determining a position of a routing node and terminal equipment. Where the method includes: generating a 0-th generation routing node deployment scheme set according to a link connection relationship among sensor nodes, a gateway node and deployable routing nodes in a network; calculating a fitness of each routing node deployment scheme in a j-th generation routing node deployment scheme set; processing the j-th generation routing node deployment scheme set according to the fitness; and selecting a routing node deployment scheme from the routing node deployment scheme set satisfying the predetermined condition. In determining a position of a routing node, optimizing the number of routing nodes and optimizing routing paths are both taken into account, thereby obtaining a routing node deployment scheme with minimum routing nodes and which can also ensure data transmission performance of the network.
