Crowdsourcing applications are vulnerable to malicious behaviors, posing serious threats to their adoption and large deployment. Based on the notion that the requestor (i.e., the crowdsourcer) can block malicious behaviors via leveraging the market power through task allocation and pricing, we propose two novel frameworks based on the mechanism design game theory (i.e., the reverse game theory). To...
Massively Multiplayer Online Role-playing Games (MMORPGs) feature a large number of players socially interacting with one another in an immersive gaming environment. A successful MMORPG should engage players and meet their needs to achieve different categories of gratifications. Research on the evolution of player social interaction network and the dynamics of inter-player intimacy could provide insights...
In this paper, we present a novel concept in proxy signature by introducing a trusted proxy agent called mediator together with a proxy signer, which enables an efficient revocation of signing capability within the delegation period, by controlling the signing capability of proxy signer even before/after generating the signature by the designated proxy signer. We describe a secure designated proxy...
An auction-based game is formulated for coordinating the charging of a population of electric vehicles (EVs) over a finite horizon. The proposed auction requires individual EVs to submit bid profiles that have dimension equal to two times the number of time-steps in the horizon. They compete for energy allocation at each time-step. Use of the progressive second price (PSP) auction mechanism ensures...
The paper deals with the concepts of core and Weber set with a priori unions of multi-choice games. As far as we know, the approach to multi-choice games with a priori unions has never been studied from the coalitional point of view. Thus we define the coalitional core and coalitional Weber set and characterize the class of convex multi-choice games with a priori unions by means of the relationships...
The complex transport facilities and conditions lead to the competition among different traffic intersections under the conditions of limited transportation resource. So the traffic intersection coordination is a game problem. Combining the game theory and reinforcement learning method, we propose a traffic intersection coordinating game model and solve the equilibrium of game by using the reinforcement...
