In this paper, we have investigated several aspects of multiplicative spread spectrum (MSS) embedding for Data Hiding. First, we analyze the probability of error of the maximum lik...
Abstract-- In this paper, we propose an evolutionary gametheoretic framework for hybrid additive white Gaussian noise multiple access channels. We consider a communication system c...
We study the joint allocation of three types of resources, namely, power, subcarriers and relay nodes, in cooperative two-hop multi-relay OFDM systems. Each relay adopts the amplif...
This paper presents a novel mechanism for dynamic rate control of prioritised Voice Over IP (VoIP) traffic in real time. The system uses our proposed variable bit rate speech codec...
Abstract--Current multibeam satellite systems perform centralized power and carrier allocation assuming a Multi-Frequency Time Division Multiple Access (MF-TDMA) scheme with fixed ...
We consider the design and performance analysis of adaptive modulation and coding (AMC) applied to regenerative dual-hop transmission systems, where a source node communicates with...
Abstract--Node mobility has a direct impact on the performance evaluation of various network mobility protocols. Unfortunately, most of the analysis on mobility protocols used Rand...
In this paper we discuss the design of optimization algorithms for cognitive wireless networks (CWNs). Maximizing the perceived network performance towards applications by selectin...
A challenging research issue of analyzing networks where packets are served probabilistically, such as multi-access networks and wireless networks, is to characterize the stochasti...
A large number of network applications today allow several users to interact together using the many-to-many service mode. A many-to-many session consists of group of users (we ref...
