Abstract Test card for color TV is a widely used method to evaluate the quality of a TV set directly. We have made a test signal generator (which can also generate synchronizing (abbreviated to sync hereafter) signals) mainly based on microprocessor Z-80. Taking the advantage of microprocessor programming, combining with the technique of microprocessor, digital circuits and analogue devices, we use software as far as possible to generate signals directly or to simplify the controlling circuits. Those signals, such as composite sync signal, bla ....etc

Abstract Broadcast is an essential and widely used operation in multihop wireless networks. Minimum latency broadcast scheduling (MLBS) aims to find a collision-free scheduling for broadcast with the minimum latency. Previous work on MLBS mostly assumes that nodes are always active, and, thus, is not suitable for duty-cycled scenarios. In this paper, we investigate the MLBS problem in duty-cycled multihop wireless networks (MLBSDC problem). We prove both the one-to-all and the all-to-all MLBSDC problems to be NP-hard. We propose a novel approx ....etc

Abstract In recent years, there has been a significant amount of work done in developing low-complexity scheduling schemes to achieve high performance in multihop wireless networks. A centralized suboptimal scheduling policy, called Greedy Maximal Scheduling ( GMS) is a good candidate because its empirically observed performance is close to optimal in a variety of network settings. However, its distributed realization requires high complexity, which becomes a major obstacle for practical implementation. In this paper, we develop simple distrib ....etc

Abstract

In this thesis, the impact of packet losses on the quality of received videos sent across a network that exhibit normal network perturbations such as jitters, delays, packet drops etc has been examined. Dynamic behavior of a normal network has been simulated using Linux and the Network Emulator (NetEm). Peoples perceptions on the quality of the received video were used in rating the qualities of several videos with differing speeds. In accordance with ITU s guideline of using Mean Opinion Scores (MOS), the effects of packet drops we ....etc

An Efficient and Fair Scheduling Scheme for
Multiuser OFDM Wireless Networks



Abstract

This paper proposes a new MAC scheduling scheme
for efficient support of multimedia services in multiuser OFDM
wireless networks, both in the uplink and in the downlink. This
scheme is based on a system of weights that dynamically accounts
for the experienced QoS and the transmission conditions in
an extended higher layers/MAC/PHY cross layer design.

Abstract
As the Internet takes an increasingly central role in our communications infrastructure, the slow convergence of routing protocols after a network failure becomes a growing problem. To assure fast recovery from page link and node failures in IP networks, we present a new recovery scheme ....etc

Delay Analysis for Maximal Scheduling With Flow Control in Wireless Networks With Bursty Traffic

We consider the delay properties of one-hop networks with general interference constraints and multiple traffic streams with time-correlated arrivals. We first treat the case when arrivals are modulated by independent finite state Markov chains. We show that the well known maximal scheduling algorithm achieves average delay that grows at most logarithmically in the largest number of interferers at any link. Furth ....etc
