We consider a multi-user mobile cloud computingsystem with a computing access point (CAP) where eachmobile user has multiple dependent tasks to be processedusing a round-by-round schedule. The CAP can either processthe received tasks from mobile users or offload them tothe cloud. In each round, we aim to jointly optimize theoffloading decisions of all users and the CAP, together withcommunication...
We consider a mobile cloud computing system consisting of multiple users, one computing access point (CAP), and one remote cloud server. The CAP can either process the received tasks from mobile users or offload them to the cloud. We aim to jointly optimize the offloading decisions of all users and the CAP, together with communication and processing resource allocation, to minimize the overall cost...
In this paper, we study power allocation (PA) in a single-relay OFDM system with limited feedback. We propose a PA scheme that uses a codebook of quantized PA vectors designed offline and known to the source, relay, and destination. The destination, which has full knowledge of channel side information (CSI), chooses one of the codebook vectors and conveys back to the source and relay. With the limited...
E-learning has been an important way, method, target and criterion of modern teaching. E-assessment is an important component of e-learning and e-qualification. Item Banks using Item Response Theory are the basis of e-assessment. With the application of WEB technology, how to share item bank resources becomes one of the problems to be solved imperatively in e-assessment. This paper proposes a grid-based...
As the band of networks increases, the process speed of network-based intrusion detection system (NIDS) hardly keeps up with the speed of networks. By arranging several sensors to deal with the traffic in parallel, the intrusion detection system's speed can be significantly increased. How to split the traffic to the sensors is the key problem of a parallel intrusion detection system. To resolve the...
