The application of mathematical analysis to the study of wireless ad hoc networks has met with limited success due to the complexity of mobility and traffic models, the dynamic topology, and the unpredictability of link quality that characterize such networks. The ability to model individual, independent decision makers whose actions potentially affect all(More)
Direct extensions of distributed greedy interference avoidance (IA) techniques developed for centralized networks to networks with multiple distributed receivers (as in ad hoc networks) are not guaranteed to converge. Motivated by this fact, we develop a waveform adaptation (WA) algorithm framework for IA based on potential game theory. The potential game(More)
In wireless ad hoc network medium access control (MAC) protocol design, it is important to incorporate an exclusion region around a receiver, such that nodes inside the exclusion region are not allowed to transmit, to limit the interference caused to the receiver. In this paper, we investigate the performance trends of a spread-spectrum-based network with(More)
Cognitive radio (CR) is an enabling technology for numerous new capabilities such as dynamic spectrum access, spectrum markets, and self-organizing networks. To realize this diverse set of applications, CR researchers leverage a variety of artificial intelligence (AI) techniques. To help researchers better understand the practical implications of AI to(More)
A framework to construct convergent interference avoidance (IA) algorithms in networks with multiple distributed receivers (as in ad hoc networks) based on potential game theory is developed in this paper. This is motivated by the fact that direct extensions of distributed greedy IA techniques for centralized networks to these de-centralized networks do not(More)
The Software-Defined Radio (SDR) research community currently needs an implementation of the SCA core framework (CF) that is open to modifications, free, simple, and in C++. Recognizing this need Virginia Tech has developed and released OSSIE (Open Source SCA Implementation::Embedded). This paper describes the underlying philosophy for the development of(More)
BACKGROUND In 2004, the Moldovan government introduced mandatory (social) health insurance (MHI) with the goals of sustainable health financing and improved access to services for poorer sections of the population. The government pays contributions for non-employed groups but the self-employed, which in Moldova include many agricultural workers, must(More)
It is shown in this paper that direct extensions of distributed greedy Interference Avoidance (IA) techniques for networks with centralized receivers to networks with multiple uncoordinated receivers (as in ad-hoc networks) do not always lead to convergence and some channel conditions that lead to non-convergence are identified. A framework based on(More)
