Description

A kind of wireless aware environment invasion object method based on Nash Equilibrium grade optimizing
Technical field
The invention belongs to the data acquisition and transmission research field under radio sensing network, and in particular to Yi Zhongji Wireless aware environment invasion object method in Nash Equilibrium grade optimizing.
Background technology
In bad environments or the artificial investigation scene of replacement, can realize that environment enters using wireless sensor node The process of subject perceptions and information transfer is invaded, but, how accurate recognition is invaded object and selects detection information Selecting optimized route carries out information transfer, and this process needs to be implemented in radio sensing network, by This, will certainly cause the problems of energy consumption and group of networks stretching frame of wireless vibration detection node and communication node The trend of structure random adaptation sexual disorder.In order to alleviate the problems referred to above, by the adaptive spy of Nash Equilibrium The thought for trusting classification is incorporated into wireless aware environment invasion object domain, while setting up Nash Equilibrium by point Mathematics betting model, from the layer that environment invades object shockproofness and wireless aware information router path optimization Close in face, the mutual suppression that can effectively balance environment invasion object solution identification and the quasi- time performance of information transmission System.
Content of the invention
It is an object of the invention on the one hand strengthen the autonomous selectivity that vibrations node perceived environment invades object, On the other hand the ability of the optimization information transmission of radio sensing network is improved, by providing based on Nash Equilibrium etc. The wireless aware environment invasion object method that level optimizes is achieved.
To achieve these goals, the technical solution used in the present invention is：Comprise the steps：
Step 1, foundation environment invade object shockproofness, divide environment invasion object and detect that vibrations node is closed Connection mapping table；
Step 2, according to environment invade object with detection vibrations node relationship maps table, realize vibrations sensing node Autonomous perception and communication behavior, set up perceive vibration information transmission Nash Equilibrium model；
Step 3, the Nash Equilibrium model transmitted based on perception information, are built and perceive vibrations node reliability rating The matrix analyses process of behavioral strategy；
Step 4, solution grade behavioral strategy matrix equation characteristic solution, obtain environment invasion object optimization and perceive knot Really.
In described step 1 according to environment invade object shockproofness ss, set ss spans (0,1], Spatial information, sensitiveness to shock, ID data according to the prior typing of vibration detection sensor node, realizes inspection Survey the mapping association table of vibrations node and invasion object shockproofness under unknown actual measurement environment.
In described step 2 perceive vibration information transmission Nash Equilibrium model as follows, participate in perceive vibrations with The participation node set of communication game is P={ source sensing node, route transfer end node 1 ... ..., route Transfer end node n, terminal sensing node }, the communication expected value based on each intrusion detection link lower node is most Bigization, chooses the strategy interaction that participant participates in game, and the utility function that tactful game is chosen is designated as The implementation strategy st of stpi (ct), participant pi under certain communication task ct that specifies.
The matrix for perceiving the behavioral strategy of vibrations node reliability rating in described step 3 sets up process as follows, (1) Establish the participant Pi participation cooperative behaviors functional vector set that vibrations are perceived and communicatedΨPMatrix for 1 × n dimensions；(2) establish participant Pi and look on cooperative behaviors Functional vector setΨBMatrix for 1 × n dimensions；(3) participant Pi is established Participate in integrated contributory factor set under the associated trust level of cooperationF is 1 × n The matrix of dimension；(4) participant P is establishediLook on integrated contributory factor set under the associated trust level of cooperationF is the matrix of 1 × n dimensions；(5) participant's Pi action-function squares are established Battle array
The derivation for obtaining environment invasion object optimization perception in described step 4 is as follows, calculates MP eigenvalues Vectorial λ=［ λ1, λ2... λn], then by ss numerical value and λiAssociation, with λiFor judgment criteria, realize that environment invasion is right As perceiving and information transfer optimum solution.
Compared with current wireless sensor technology, wireless aware environment of the present invention based on Nash Equilibrium grade optimizing Invasion object method sets up environment invasion object and detection vibrations node relationship maps table in advance, then sets up sense Know the Nash Equilibrium model of vibration information transmission, finally realize the behavioral strategy for perceiving vibrations node reliability rating Matrix derive, obtain environment invasion process identification and information transmission optimize solution.The inventive method Effectively can balance environment invasion process identification and the quasi- time performance of information transmission mutual suppression relation, one Aspect, realizes environment invasion process identification process inside radio sensing network in advance；On the other hand in identification In the middle of process, by the integrated optimization process of Nash Equilibrium reliability rating division methods, detection vibrations letter is realized Breath route optimal solution.
