In order to solve the problem that the existing resource allocation strategies cannot give
integrative consideration to QoS, spectrum efficiency for mixed traffic, this paper proposes a …

By supporting advanced multimedia applications and multitasking, recent Smartphone
operation systems offer great flexibility to the users but make these devices even more …

The problem of maximizing a utility function while limiting the outage probability below an
appropriate threshold is investigated. A coded-division multi access wireless network under …

This paper proposes a joint routing and spectrum partitioning algorithm for cellular network
enhanced with two-hop fixed relay nodes (RNs) in 3GPP LTE-Advanced. To better improve …

Utility functions are widely used to model user perceived service quality. For elastic traffic,
the utility function is often increasing and strictly concave. An elastic allocation (EA) …

With the rapidly growing deployment of high performance mobile terminals, such as smart
phones, multitasking becomes one of the popular uses of mobile services. As the user …

A promising approach to alleviate ISM band congestion problems in highly dense WLAN
scenarios consists of exploiting opportunistic spectrum access (OSA) to underutilized bands …

Traffic density in wireless networks is time-and space-varying as users move from one area
to another. For example, the majority of traffic stays in residential areas in the early morning …

The radio interface of cellular mobile communication systems is normally considered as the
only capacity limiting factor in the radio access network. However, as enhanced radio …

To meet rapidly increasing traffic demands caused by the popularization of Internet and the
spouting of bandwidth-demanding applications, Passive Optical Networks (PONs) exploit …
