Cloud Entropy Management System Involving a Fractional Power

Abstract: Cloud computing (CC) capacities deliver high quality, connected with demand services and service-oriented construction. Nevertheless, a cloud service (CS) is normally derived from numerous stages of facilities and concert features, which determine the value of the cloud service. Therefore, it is problematic for the users to estimate these cloud services and select them to appropriate their requirements. In this study, a new algorithm is carried out for a multi-agent system (MAS) based on fractional power. The study depends on a fractional difference equation of type two point boundary value problem (BVP) based on the fractional entropy. We discuss the existence of solutions for the system as well as the stability, utilizing the Hadamard well-posed problem. Experimental results show that the proposed method demonstrates stability and performance.


Introduction
Recently, numerous huge groups such as Google, Amazon, etc., have capitalized on massive data centers (DC).These funds have still not achieved rising client supplies.Nevertheless, the process and conservation budget of such data centers is significant.Therefore, to reduce the DC overall budget, these groups have started moving to cloud computing (CC), as service benefactors.
The aim of CC is to optimize the tradition of software resources, physical, develops suppleness and mechanizes organization, which is consequently realized as a method to reduce costs and to increase income for cloud service sources.The achievement of CC will be contingent on how successfully it: drives skilled to instantiate and dynamically working computing platforms, is constructed out of cloud service (CS), and encompasses the arbitrarily varying service requirements of cloud costumers.Usually, these services will be described by the quality of CS requirements, such as capability, timeliness, high availability, security, trust, etc.Moreover, the assistance of CC comes from new experiments such as security, consistency, etc., that must be suitably addressed.Consequently, corresponding and defining the best cloud for a modified request is significant and often controls the achievement of the fundamental business of the cloud users.
Multi-agent system (MAS) are significant classification schemes because of their trade and armed requests.Saber et al. [1] introduced multi-agent systems, with a stress on the attractiveness of the fixed data flow, strength to variations in network topology due to link/node failures, performance guarantees and time-delays.Xie and Wang [2] imposed the consensus of second order discrete time MAS with fixed topology.Ma et al. [3] reflected the group consensus problem of second-order nonlinear multi-agent systems through leader-following approach and pinning control.Recently, Meng et al. [4] studied finite time multi-agent consensus problems under networks based on signed graphs whose edge weights can be not only positive but also negative.Chu et al. [5] investigated the agreement tracking problem for MAS with direct graph applying the Lyapunov function.The fractional integral system in the economy was suggested for the first time by Baillie [6].Studies of the multi-agent systems focus fundamentally on integer calculus, whose dynamical equations are ordinary differential equations.However, various MAS cannot be deliberated with the integer cases in the complex physical situation, although they only are selected with fractional order (non-integer) differential equations.Recently, fractional economic systems have been investigated by Machado and Mata [7,8].
The distributed work is based on three factors; database, platform and service node.Moreover, cloud computing depends on a large number of users and in the normal structure the load is not equal.The changing of the load casues the usage of various classes of difference equations.In addition, this class provides a good comparison and improves the quality of the cloud service.The applications show the simplicity and validity of our system, which has perfect usability, reliability and stability.We shall consider a special type of fractional power operator.This operator allows us to make sure that there is a connection between the users in the cloud system.This connection can be controlled by employing a sufficient fractional power.Another reason to utilize the difference equation is that the database is distributed and shared between different computers.The database system involves one logical database, which is divided into various segments.Each segment is stored in one or more computers which are connected by a communication network.
In 1974, Diaz and Osler [9] carried out a discrete fractional difference operator founded by infinite power series.In 1988, Gray and Zhang [10] offered a group of fractional difference operators and presented the Leibniz formal.In 2009, Atici and Eloe [11] announced the approaches for composing fractional differences and sums.Mathematicians, physicists, and engineers have lately been employing fractional calculus to explain and model changes of applied problems in diverse areas.Recently, Ibrahim and Jalab [12,13] investigated a positive solution of discrete fractional boundary value problems for continuous Gâteaux differentiable functions.A generalized Gâteaux derivative is introduced by employing a fractional discrete operator.
In this study, a new algorithm is carried out for an entropy MAS based on fractional power.The study depends on a fractional difference equation of type two point boundary value problem (fractional boundary value problem (BVP)).We discuss the existence of solutions for the system as well as the stability, utilizing the Hadamard well-posed problem.Experimental outcomes show that the proposed method is furnished with stability and performance.

Formal Algorithm
The formal emphasis is upon the influence of the overall trend of choices of technology transition times.In this setting, a continuum of agents having non homogenous preferences, pay a cost to transfer from one point to another point in the state space.Assume that there are n agents whose communication network is a directed graph.The agent i has the cost function Φ i pt, χ, u, µq ; χ : " pχ 1 , . . ., χ n q J , u : " pu 1 , . . ., u n q J and µ : " pµ 1 , . . ., µ n q J ; representing what an agent pays to have the features χ i ptq (i.e., the level of cloud computing at time t) under the controller input u i ptq and the density µ i ptq of the population for a given level of χ i ptq .It has been shown that the integer linear system is a distributed agreement algorithm [14] such that α ij ą 0 is the pi, jq (agent i can receive information from agent j, otherwise α ij " 0) element of the adjacency matrix Λ.The contract is asymptotically touched when the mutual conclusion is equivalent to the average of the initial state of all agents.
A consensus algorithm with this specific invariance property is called an average-agreement algorithm and has wide implications on distributed computing in networks h " In this study, we deal with a multi-agent system of fractional difference equations of type two points BVP, taking the formal where p, q, r are constants, 0 ă α ă 1, 0 ă 5 " N{n ă N, t i " i5, i " 0, . . ., n ´1 and α is defined by It is clear that the extended binomial coefficients satisfies 0 ă β pn ´1, α; iq ď 1 for all α P r0, 1s (see [14,15]).
Recently, fractional entropy has played an important role in improving many results in various applications in science engineering.In [16], Tsallis imposed a fractional entropy, which is a modification of Shannon entropy.In [17], Mathai and Haubold generalized the Tsallis formula.Machado recently considered a novel formula for entropy by applying fractional calculus [18].Ibrahim and Jalab employed the fractional entropy in image processing and dynamical systems [19][20][21].The arrangement of multiple managers on a particular physical machine increases various security concerns.Many of these concerns are associated with problems that multi-agent systems had to address when they went from the single agent to MAS.Of chief concern is keeping one user's data, programs, activity and resources separate from all others.Usually, to avoid these weaknesses, a modified cloud entropy management system is considered and employed [22][23][24][25].
By employing the fractional Tsallis entropy, given by T γ pβq pxq " or in a discreet form and by using the coefficients β pm, α; iq ď 1, we have the following modify entropy: for a suitable α and a large value of m, we suggest a new difference operator of the formal ˆ α γ χ n " βγ pn ´1, α; iq χ i ´β0 χ 0 where βγ pn ´1, α; iq " Our aim is to study the multi-agent system of fractional difference equations of type two points BVP, taking the formal Subjected to the following boundary condition (BC): where Φ i pt, χ, u, µq is the cost function for all agents in the cloud system.

Findings
The mathematical concept well-posed problem (or Hadamard well-posed) is defined as the mathematical platforms of physical phenomena that should have properties such that: (i) A solution exists; (ii) The solution is unique; (iii) The solution's behavior changes continuously with the initial conditions.Otherwise, it is called ill-posed.It is well known that, if the problem is well-posed, then it can be viewed as a good algorithm of outcome on a computer employing a stable algorithm.Since the system Equation ( 1) is formulated for multi users, it is enough to show that Equation (1) has multi-solutions.In this case, we satisfy part (i) of the well-posed problem.

Uniqueness
The main result can be formulated as follows: Theorem 3.1.Let Φ i : r0, Ns ˆR3 Ñ R be continuous and p `q ‰ 0.
Suppose that there exist constants κ P p0, Nq , ℘ ą 1, and a positive function : r0, Ns Ñ R `.If |Φ i pt, χ, u pt, χq , µ pt, χqq ´Φi pt, r χ, u pt, r χq , µ pt, r χqq| ď ptq p|χ ´r χ|q , `@ t P r0, Ns , pu, µq P R 2 , ˘ Proof.Consider the complete metric space `Ξ : " R n`1 , d ℘ ˘and for all µ, ν P Ξ System (1) can be viewed as the following summation equation: where We aim to show that Equation (1) has a unique solution.Define the following operator: So that pΛµq " ppΛχq p0q , . . ., pΛχq pn ´1qq Evidently, Λ pχq is bounded φ pi, jq βγ pn ´1, α; jq rΦ i pt, χ, u, µq `Φi pt, 0, 0, 0q ´Φi pt, 0, 0, 0qs where 0 is the zero element in R n .. We proceed to demonstrate that pΛχq " χ for a unique χ P Ξ.Since Φ i is well-defined on r0, Ns ˆR3 , it implies that Λ : Ξ Ñ Ξ.We display that Λ is a contraction mapping on Ξ with respect d ℘ , i.e., there is a constant 0 ă σ ă 1 such that Consequently, we obtain d ℘ ppΛχq , pΛ r χqq ď σd ℘ pχ, r χq where 0 ă σ : " nκ α Lφβ ă 1.Thus, Λ is a contraction mapping on R n with respect to the d ℘ metric and thus, all of the conditions of Banach's fixed point theorem valid.Therefore, there exists a unique solution χ P R n such that Λχ " χ.This completes the proof.˝ Proof.Consider the metric space pΞ : " R n , Bq and for all χ, r χ P Ξ B pχ, r χq " max i |χ i ´r χ i |, χ " pχ 1 , . . ., χ n q , r χ " p r χ 1 , . . ., r χ n q It is easy to show that pΞ, Bq is a complete metric space.By the assumption, we conclude that 0 ă βγ pn ´1, α; jq ă 1, for all j, then operator Equation ( 4 Hence, Λ is a contraction mapping on R n with respect to the B metric and so, all of the conditions of the Banach fixed point theorem archived.Therefore, there is a unique χ P R n such that Λ χ = χ, implying the existence of a unique solution to the problem Equation (1).
There are various well-known cloud computing service suppliers, such as, Google, Amazon, IBM and Microsoft, etc.How should one select the furthermost proper cloud service for owners from the suppliers?It has been shown that information-entropy is the best method for the selection of cloud computing services.We believe that system Equation ( 1) can be used for this purpose, because it calculates the entropy of the cost function of the multi-agent system.Consequently, affording the difference equation involving the entropy, and the evaluation values given by experts for each case, we may conclude that the cloud tends to be a more objective and reasonable one.
