Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of block chain resources configuration optimization sides based on secondary auction
Method and device.
Background technique
When block chain is combined with Internet of Things infrastructure, since internet of things equipment computing resource is limited, and block chain
It is the common recognition mechanism based on proof of work mechanism (PoW, Proof of Power) Lai Shixian decentralization, so Internet of Things
Infrastructure is unable to satisfy demand of the PoW to electric power and the energy.Therefore, it finds a kind of efficient and rational based on block chain technology
Edge calculations resource distribution mode is to construct the distributed edge based on block chain to calculate service architecture, and it is whole to improve internet of things equipment
Body performance ensures reliability and the security critical place of data.
In the prior art, a kind of scheme is: in the condition for guaranteeing to be no more than the calculation power upper limit that edge calculations server provides
Under, the total revenue of system is described as to optimize TRO problem.To solve the problems, such as that TRO is converted to TRO-sub problem first by TRO, this
It is a stringent convex optimization problem, the optimal solution of subproblem can be obtained under the conditions of based on KKT by Lagrangian,
For TRO problem, reasonable step-length is set by the way of linear search, global optimal solution is obtained by way of enumerating,
Then it solves the problems, such as TRO, realizes the resource allocation of edge calculations server.
Another scheme is: the calculating task of block chain node being unloaded to the edge calculations server closed on, at edge
Calculation server there are resource constraint in the case where by VCG (Vickrey-Clarke-Groves auction) auction side
Formula is allocated computing resource, and block chain node sends resource requirement and corresponding quotation to edge calculations servers, so
Server determines auction victor's list to maximize server income as target afterwards, true as target to maximize server income
Surely the real price of victor is auctioned.
For the first above-mentioned scheme, realize edge calculations server to mobile block chain link by solving the problems, such as TRO
The resource allocation of point.But in actual resource allocation process, different blocks chain node has different computational resource requirements,
The method does not account for the decision-making capability of block chain node, and computing resource is not allowed to carry out personalized distribution, computing resource
Flexibility in assigning process is insufficient.In addition to this, the method do not account in mobile block chain network yet peer node it
Between resource interaction scenario, and do not meet the existing edge calculations service architecture based on block chain.
Edge is realized by the method for VCG auction to maximize server income as target for above-mentioned second scheme
The computational resource allocation of calculation server can be realized edge calculations server computing resource and reasonably flexibly distribute.But
There is no the resource allocation methods of design subsequent to the block chain node for still remaining certain computing capability to fail in auction process,
Cause the waste of computing resource.Meanwhile the method does not account for the resource friendship of peer node in mobile block chain network yet
Mutual situation significantly reduces the income of block chain node, is unfavorable for although realizing the maximization of server income
The efficient operation of total system.

Function, giFor the computing capability of node i itself, ∑j∈N(gj+djxj) be entire block chain network entirety computing capability, λ be it is constant
Parameter, τiThe propagation time of block is generated for node i.
Because the generating process of block and the process for the successful cochain of reaching common understanding are two mutually independent processes, save
Point i digs the product that the successful probability of mine is the probability gone on smoothly in two stages.
(5) R is definediMine successfully expected reward is dug for node i:
Wherein, RiMine success expected reward obtained is dug for node i, T is the fixed prize dug after mine success, and η is to be
