The distributed caching management enabled wireless networking technology can greatly improve the data storage and transmission efficiency of wireless users and correspondingly the users' quality of experience (QoE). How to alleviate the pressure on network access while ensuring the content consistency is still a challenge. In this paper, we investigate the vehicular users oriented caching management...
Resource scheduling is one of the most important problems in cloud computing. However, it is a big challenge for efficient resource scheduling algorithm design and implementation (since general scheduling problem is NP-complete). Most existing resource scheduling methods of cloud computing only consider task resource requirements for CPU and memory, without considering bandwidth requirements. In this...
The dynamic binary translation(DBT) is used to support legacy binary code, provides program instrumentation, improves code performance, and so on. The dynamic nature of the translation usually incurs extra substantial execution overhead in DBT systems. As a result, DBT may be impractically slow if it do not or can not employ optimizations to offset the overhead. This paper investigates a few optimizations...
Multiuser orthogonal frequency division multiplexing (MU-OFDM) is a promising technique for achieving high downlink capacities in future cellular and wireless local area network systems. The capacity of MU-OFDM can be maximized as long as subchannels and power are allocated adaptively, a new method based on genetic algorithm (GA) is proposed for adaptive power allocation in MU-OFDM system. Some proportional...
