The cellular data traffic has been dramatically increased, a typical approach is considering the operation of the Long Term Evolution (LTE) system in the unlicensed spectrum. Although there are a large number of theoretical researches on LTE-U, field trial results are still lacking. In this paper, we build a real time field trial in 5.8GHz unlicensed bands. The typical indoor scenario is deployed...
In response to ever-increasing of mobile broadband data traffic demands, integrating unlicensed carrier into the traditional LTE system on licensed spectrum, namely Unlicensed LTE (U-LTE), is an effective solution. Considering that the unlicensed spectrum is shared by a variety of communication systems such as the Wi-Fi system, one essential target of U-LTE design is to guarantee fair co-existence...
Video delivery performance is the main factor that affects Internet video quality. Characterizing the video delivery performance, especially the delivery throughput, can help content providers as well as Internet service providers (ISPs) in system optimization and network planning. Based on a unique dataset consisting of 20 million video download speed measurements , this paper comprehensively studies...
This article presents SOFIA, a service-oriented information-centric networking architecture. SOFIA is designed by exploring the design space between host abstraction and content abstraction. It can facilitate ICN to easily support various applications beyond content retrieval. SOFIA decouples flexible service processing and efficient data transmission into two stack layers: the service and network...
