[0032] figure 1 The detailed flow of the 3DYAO-based two-dimensional bounded three-dimensional sensor network topology control method described in the present invention is given, and the specific technical implementation plan is as follows:
[0033] Step 1: For any node u in a given wireless sensor network, calculate its neighbor node set N UBG (u). The specific calculation method is as follows:
[0034] Take the node u as the center of the sphere, and take the maximum communication distance R that the wireless sensor node transmit power can reach as the radius to form a sphere. In a given 3D wireless sensor network, if a node v falls within a sphere, then v is a neighbor node of u. All nodes v constitute u's neighbor node set N UBG (u).
[0035] Step 2: Use the 3DYAO algorithm to set the neighbor node set N of node u UBG (u) Process to get the neighbor node set N processed by node u YG (u).
[0036] As a preferred embodiment of the present invention, the 3DYAO algorithm...

The invention relates to a three-dimensional wireless sensor network topology control method with a two-dimensional bounded property. The method comprises the following steps that: step one, with regard to a random node u, a neighboring node set NUBG (u) of the random node u is calculated; step two, a 3DYAO algorithm is utilized to carry out processing on the NUBG (u) to obtain an NYG (u); step three, the NYG (u) is broadcasted for the NUBG (u); step four, an introverted neighboring set of the node u is calculated; step five, the same 3DYAO algorithm used in the step two is used to carry out processing on the introverted neighboring set to obtain a processed neighboring node set of the node u; step six, the processed neighboring node set is broadcasted for all neighbors in the NUBG (u); step seven, for all nodes v in the NYG (u), if the u is also in the processed neighboring node set, the v is added into an NYYG (u); and step eight, a two-dimensional bounded three-dimensional wireless sensor network topology NYYG (u) of the node u is output and a transmitting power is adjusted as being capable of reaching a farthest neighboring position in the NYYG (u). According to the invention, the method has two-dimensional bounded and high efficient energy saving characteristics; an objective of locally distributed realization can be achieved; network life cycle can be extended; a network interference can be reduced; and an objective of improvement of a network throughput rate can also be achieved.
