Offloading computation to a mobile cloud is a promising approach for enabling the use of computationally intensive applications by mobile devices. In this paper we consider autonomous devices that maximize their own performance by choosing one of many wireless access points for computation offloading. We develop a game theoretic model of the problem, prove the existence of pure strategy Nash equilibria,...
This work studies the social-aware joint issue of mode selection and link allocation over mobile device-to-device (D2D) communications underlaying cellular networks. We first model this joint problem as a hedonic coalition formation game, which considers the tradeoff between the benefits in terms of achievable rate and the costs in terms of the mutual interference. Importantly, we introduce the local...
Selecting and prioritizing major device models are critical for mobile app developers to select testbeds and optimize resources such as marketing and quality-assurance resources. The heavily fragmented distribution of Android devices makes it challenging to select a few major device models out of thousands of models available on the market. Currently app developers usually rely on some reported or...
In this work, we study the problem of green uplink resource sharing over mobile device-to-device (D2D) communications underlaying cellular network. We first construct a analysis model of energy efficiency, which takes into account different sharing modes, as well as QoS requirement and spectrum utilization of each user. Then, we formulate the sharing problem as a non-transferable coalition formation...
Advanced mobile devices such as smartphones have become a part of daily lives for digital native students today. We believe that the integration of mobile computing into computer science (CS) curricula with smart mobile devices based learning tools will connect the education to leading-edge information technologies, motivate and engage students in CS learning, innovate CS education, fill in the gap...
This paper proposes a service management method for P2P MMOG, which adopts the ideas of Web service, all the computing functions are encapsulated in services, and several service nodes provide services for P2P MMOG collaboratively. In order to balance the load of system, at first judge migration opportunity according to the load capacity of service nodes, then target service is selected in terms of...
Cooperative forwarding in wireless networks has shown to yield benefits of rate and diversity gains, but it needs to be incentivized due to the energy and delay costs incurred by individual nodes in such cooperation. In this paper we consider an incentive mechanism called Bandwidth Exchange (BE) where the cooperating nodes flexibly exchange the transmission bandwidth (spectrum) as a means of providing...
