Modern map services and other spatial systems must support a wide range of applications. Besides computing optimal (with respect to a cost function such as travel times or time in traffic) point-to-point routes, advanced queries like “find the closest Thai restaurant to my current location” or “what is the best place to stop for groceries […]
Cloud Gaming Experience Towards Placing Virtual Machines Optimizing
This paper tackles the challenge and study an optimization problem to maximize the cloud gaming provider’s total profit while achieving just-good-enough QoE. We conduct measurement studies to derive the QoE and performance models. We formulate and optimally solve the problem. We conduct extensive measurement studies using an open-source cloud gaming platform, GamingAny-where (GA) on two […]
A NOVEL DISTRIBUTED FAULT-TOLERANT TOPOLOGY CONTROL ALGORITHM FOR HETEROGENEOUS WIRELESS SENSOR NETWORKS
In this abstract, we focus on a proactive fault-tolerant topology control algorithm in heterogeneous WSNs with a two-layered architecture where the lower layer consists of low-cost ordinary sensor nodes, with limited battery power and short transmission range. The upper layer consists of super nodes, which have more power reserves and better processing and storage capabilities. […]
