In this paper, we present a QoS-adaptive framework for screen sharing over heterogeneous networks. Basic requirements and important issues of a screen sharing system are described. For determining optimal video coding parameters, adaptation trajectory is used as the hints in making decisions. Further, experiments are carried out to investigate the trade-off between video bitrate and the buffering...
This paper assesses the drawbacks in reconfigura-bility and resource consumption of the conventional baseband signal processing circuitry for modern Global Navigation Satellite Systems (GNSSs) signals. The involvement of new GNSSs leads to the requirement of designing a programmable multi-GNSS baseband receiver that can be reconfigured across GNSS signals. Paralleling baseband circuits is the easiest...
We investigate the achievable throughput regions for scenarios involving prioritized transmissions. Prioritized transmissions are useful in many multimedia networking applications where the transmitted data have an inherent hierarchy such that a piece of data at one level is only useful if all the pieces of data at all the lower levels are present. Formally, the prioritized transmission refers to...
We investigate the power consumption and bandwidth usage for information exchange between two terminal nodes in a linear wireless ad hoc network. Specifically, we propose a joint network coding and adaptive power control (NCPC) scheme which regulates the transmission power to reduce the overall energy usage and to increase the bandwidth efficiency. Analysis and numerical results show that our proposed...
In this paper, we investigate a hybrid network coding technique to be used at a wireless base station (BS) or access point (AP) to increase the throughput efficiency of single-hop wireless networks. Traditionally, to provide reliability, lost packets from different flows (applications) are retransmitted separately, leading to inefficient use of wireless bandwidth. Using the proposed hybrid network...
