Navigation of autonomous mobile robots in connected groups
(IEEE, 2008)
The navigation of autonomous mobile robots as a group is considered in this paper. Definitions adopted from the graph theory are given to characterize the robot group. A local steering strategy is proposed such that when ...
Outage Diversity for Distributed Estimation over Parallel Fading Channels
(IEEE, 2008)
In this paper we study the outage diversity in distributed estimation over parallel fading channels. We find tight upper and lower bounds on the diversity order and show that they are arbitrarily close under certain ...
Distributed estimation over parallel fading channels with channel estimation error
(IEEE, 2008)
We consider distributed estimation of a source observed by sensors in additive Gaussian noise where the sensors are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. We adopt a ...
Effect of the Channel Estimation Error on the Performance of the Source Estimator in a Wireless Sensor Network with Orthogonal Channels
(IEEE, 2008)
In this work effect of the channel estimation error on the MSE performance of the source estimator in a wireless sensor network with orthogonal flat fading channels is studied. A two-phase approach was employed where in ...
A Software Component Architecture for Adaptive and Predictive Rate Control of Video Streaming
(Springer, 2008)
Quality of Service and Transmission Rate Optimization in live and on-demand video streaming is a very important issue in lossy IP networks. Infrastructure of the Internet exhibits variable bandwidths delays congestions and ...
An Integrated Software Architecture for Bandwidth Adaptive Video Streaming
(World Acad Sci Eng & Tech-Waset, 2008)
Video streaming over lossy IP networks is very important issues due to the heterogeneous structure of networks. Infrastructure of the Internet exhibits variable bandwidths delays congestions and time-varying packet losses. ...
Fast multi-view face trackingwith pose estimation
(2008)
In this paper a fast and an effective multi-view face tracking algorithm with head pose estimation is introduced. For modeling the face pose we employ a tree of boosted classifiers built using either Haar-like filters or ...
