EvalVid - A Framework for Video Transmission and Quality Evaluation
- In Proc. of the 13th International Conference on Modelling Techniques and Tools for Computer Performance Evaluation
, 2003
"... With EvalVid we present a complete framework and tool-set for evaluation of the quality of video transmitted over a real or simulated communication network. Besides measuring QoS parameters of the underlying network, like loss rates, delays, and jitter, we support also a subjective video quali ..."

Atpc: Adaptive transmission power control for wireless sensor networks
- In Proceedings of the Fourth International Conference on Embedded Networked Sensor Systems (SenSys
, 2006
"... Extensive empirical studies presented in this paper confirm that the quality of radio communication between low power sensor devices varies significantly with time and environment. This phenomenon indicates that the previous topology control solutions, which use static transmission power, transmissi ..."

of this work lies in a novel pairwise transmission power control, which is significantly different from existing node-level or network-level power control methods. Also different from most existing simulation work, the ATPC design is guided by extensive field experiments of link quality dynamics at various
Video transport over ad hoc networks: Multistream coding with multipath transport
- IEEE J. Sel. Areas Commun
, 2003
"... Abstract—Enabling video transport over ad hoc networks is more challenging than over other wireless networks. The wireless links in an ad hoc network are highly error prone and can go down frequently because of node mobility, interference, channel fading, and the lack of infrastructure. However, the ..."

Realistic and Efficient Multi-Channel Communications in Wireless Sensor Networks
"... Abstract—This paper demonstrates how to use multiple channels to improve communication performance in Wireless Sensor Networks (WSNs). We first investigate multi-channel realities in WSNs through intensive empirical experiments with Micaz motes. Our study shows that current multi-channel protocols a ..."

are not suitable for WSNs, because of the small number of available channels and unavoidable time errors found in real networks. With these observations, we propose a novel tree-based multichannel scheme for data collection applications, which allocates channels to disjoint trees and exploits parallel
Simulation Studies on Zigbee Communication for Video Transmission and Networking
"... Abstract — ZigBee is a new wireless communication technique based on the radio frequency electromagnetic waves. ZigBee is based on the IEEE 802.15.4 Standard and 128bit key and AES-128 block encryption tool with Flexible protocol design which make it suitable for many applications. It is most popula ..."

of the automation process within chemical plants, refineries, and commercial buildings. In this paper we have performed various simulations on Network Simulator version 2.29 and compared results for the three traffic types-ie. ftp, cbr, poisson. Video transmission over such networks is considered an issue since
Transmission Protocols for Streaming Video over Wireless
- in IEEE International Conference on Image Processing (ICIP
, 2004
"... for both wired and wireless networks. A widely accepted rate control method in wired networks is TCP friendly equation based rate control [1], i.e. TFRC. However, it assumes that packet loss in wired networks is primarily due to congestion, and as such is not applicable to wireless networks in which ..."

Multiple tree video multicast over wireless ad hoc networks
- IEEE Trans. on Circuits, Systems and Video Technology
, 2007
