Embodiment Construction

[0027] The present invention will be further described in detail in conjunction with the accompanying drawings, theoretical analysis and simulation tests.

[0028] The present invention provides a mobile scale-free self-organizing network model. The method first makes the following assumptions: assume that the entire simulation area of ​​the network is [X, Y], and the signal transmission radius of the node is γ 0 , signal transmission radius γ 0 0 Uniform ;Ignore the boundary effect of nodes; assume that the network initially has no nodes and edges; t is a time step, and a new node is added at each time step, and the network is generated after a total of N time steps. The value range of t is: 0<t≤N , and t is a natural number. The number of nodes after the entire network is generated is N; at the beginning t=1.

[0029] Follow the steps below to establish the mobile scale-free self-organizing network model:

Abstract

The invention discloses a method for constructing a mobile scale-free self-organized network model. The method is characterized by assuming that the whole emulated local area of a network is [X,Y], that the signal transmission radius of nodes is r0, r0 is far less than X and r0 is far less than Y, and that the node spatial distribution probability density function is the uniformly distributed pdfUniform, neglecting the border effect of the nodes, assuming the network does not have the nodes and edges at the very beginning; increasing a new node at each time step t, and assuming that t is morethan 0 and less than or equal to N and that t is a natural number. The network is constructed in N time steps, and the number of nodes is N after the whole network is constructed. The process for constructing the network model comprises the following steps of: increasing a node At for the network according to the probability PAddNode=1; establishing a connection of the node At in the local area world; and increasing eAddLong long-range connection for the node At according to the probability Paddlong. The scale-free network topology, provided by the invention, is more close to the real world. When the method is applied to the mobile self-organized network / wireless sensor network, the method has the advantages of optimizing network connectivity, prolonging the life cycle of the network, improving efficiency of the network search protocol, along with high scalability.

Description

technical field [0001] The invention belongs to the communication field and relates to a network model, in particular to a method for establishing a mobile scale-free self-organizing network model. Background technique [0002] In addition to the small-world effect of a large number of real networks, the node degree of the network may also obey the power law distribution. The node degree obeys the power law distribution, which means that the relationship between the number of nodes with a specific degree and the specific degree can be expressed approximately by a power function. The power function curve is a relatively slow descending curve, which allows nodes with a large degree to exist in the network. For random networks and regular networks, the degree distribution interval is very narrow, and it is almost impossible to find points that deviate from the mean value of the node degree, so the average degree can be regarded as a characteristic scale of the node degree. In...
