Virtual network resource allocation based on Stackelberg game research

چکیده
-In view of the network resources allocation problem in network virtualization environment, combined with the Stackelberg game model, this paper proposes a resources allocation scheme that can satisfy the maximum utility of the substrate network and virtual network at the same time. Firstly, it designed a utility function of virtual network based on revenue and cost, and proved in the price of the substrate network is determined, the utility function meet the conditions of concave function, which guarantee the Nash equilibrium point of non-cooperative game between the virtual network. In order to obtain the optimal bandwidth strategy in virtual network and the optimal pricing strategy in substrate network, the paper proposed a distributed iterative algorithm. Finally verified the effectiveness of the algorithm by numerical simulation experiments, and obtained the optimal strategy of players and the sub-game perfect Nash equilibrium.

A Stackelberg game-based spectrum allocation scheme in macro/femtocell hierarchical networks
Femtocells widely deployed in a macrocell form hierarchical cell networks, which can improve indoor coverage and network capacity, and have been regarded as one of the most promising approaches. However owing to the absence of coordination between the macro and femtocells, and among femtocells, decentralized spectrum allocation between macro and femtocell users become technically challenging. I...
متن کاملGame Theoretic Analysis of Security and Sustainability
Computational game theory has become a powerful tool to address critical issues in security and sustainability. Casting the security resource allocation problem as a Stackelberg game, novel algorithms have been developed to provide randomized security resource allocations. These algorithms have led to deployed security-game based decision aids for many real-world security domains including infr...

Abstract— This paper, considers a marketed small-cell caching system comprising of a Network Service Provider (NSP), a number of Video Retailers (VR), and Mobile Users (MU). The NSP rents its SBSs to the VRs intending benefits. Stackelberg game framework is used for addressing the SBSs as a particular type of resources. The MUs and SBSs as autonomous Poisson Point Processes (PPP) are used to de...
متن کاملOptimal Power Allocation for Multichannel Cognitive Radio Systems Using Stackelberg Game
We consider a non-orthogonal multiple access scheme e.g. CDMA based cellular multi-channel cognitive radio network (CRN). Here multiple secondary users share a common set of channels simultaneously. For such an environment, we develop a distributed power allocation approach based on a game theoretic formulation among secondary users to satisfy their rate requirement. We model the problem using ...
متن کاملGame-Theoretic Security Patrolling with Dynamic Execution Uncertainty and a Case Study on a Real Transit System
Attacker-Defender Stackelberg security games (SSGs) have emerged as an important research area in multi-agent systems. However, existing SSGs models yield fixed, static, schedules which fail in dynamic domains where defenders face execution uncertainty, i.e., in domains where defenders may face unanticipated disruptions of their schedules. A concrete example is an application involving checking...
