The Long Term Evolution (LTE) network is recognized as the next generation wireless network, which provides high bandwidth and low latency for emerging mobile applications. The issue of power saving is very crucial for the success of service deployment. This paper presents a novel downlink scheduling approach to reduce power consumption while maintaining the receiving quality of video streaming in...
Service delivery in a heterogeneous wireless network environment requires the selection of an optimal access network. Indeed, the selection of a non-optimal network can result in undesirable effects such as higher costs in terms of new call blocking and handoff call dropping rates or poor service experience. Network selection in such an environment is influenced by several factors related to network...
In this paper, we discuss resource management in modern wireless communications with the objective of minimizing power consumption, and carry out an analysis of simultaneous transmission and orthogonal transmission schemes in an FDMA (Frequency Division Multiple Access) framework. Based on a two-link line model with path-loss only, the performance of these two schemes for network power minimization...
In this paper, we propose a cognitive radio-based multi-user resource allocation framework for mobile ad hoc networks using multi-carrier DS CDMA modulation over a frequency-selective fading channel. In particular, given pre-existing communications in the spectrum where the system is operating, in addition to potential narrow-band interference, a channel sensing and estimation mechanism is provided...
