Claim 3:
4. The distributed task offloading and computing resources management method based on energy harvesting according to claim 1, wherein it is determined whether the optimal dynamic quotation strategy of the mobile edge computing server for the device meets the Stackelberg equilibrium, that is, in a case that a quotation of the mobile edge computing server is determined and the following equation holds:, U
    
     b
     i
    
   
   (
   
    
     b
     ij
     SE
    
    (
    t
    )
   
   )
  
  =
  
   
    sup
    
     
      
       b
       ij
       min
      
      (
      t
      )
     
     ≤
     
      
       b
       ij
      
      (
      t
      )
     
     ≤
     
      
       b
       ij
       max
      
      (
      t
      )
     
    
   
   ⁢
   
    {
    
     
      U
      
       b
       i
      
     
     (
     
      
       b
       ij
      
      (
      t
      )
     
     )
    
    }
   
  
 

and an offloading task bij(t) is determined and the following equation holds:, U
    
     s
     j
    
   
   (
   
    
     p
     ij
     SE
    
    (
    t
    )
   
   )
  
  =
  
   
    sup
    
     
      
       p
       ij
      
      (
      t
      )
     
     ≥
     
      
       p
       ij
       c
      
      (
      t
      )
     
    
   
   ⁢
   
    {
    
     
      U
      
       s
       j
      
     
     (
     
      
       p
       ij
      
      (
      t
      )
     
     )
    
    }
   
  
 

then it is determined that the optimal dynamic quotation strategy of the mobile edge computing server for the device meets the Stackelberg equilibrium;
where Ubi(bijSE(t)) represents a benefit of an i-th mobile device, where bijSE(t) represents the size of the offloading task; bijSE(t) represents a Stackelberg equilibrium solution of the size of tasks offloaded from the i-th mobile device to the j-th mobile edge computing server; bijmin(t) represents the minimum size of offloading tasks; bijmax(t) represents the maximum size of offloading tasks; Usj(pijSE(t)) represents a benefit of a j-th mobile edge computing server, where pijSE(t) represents a quotation; pijSE(t) represents a Stackelberg equilibrium solution of the quotation of the j-th mobile edge computing server for the i-th mobile device; and pijc(t) represents a cost price of the i-th mobile device performing task offloading to the j-th mobile edge computing server.
