In this article we propose a new simulation module for NS-2 able to reproduce the performance of fixed terminals operating in a wireless network with one or more antennas at the receive end, based on empirical models validated on the literature. This is relevant to perform accurate cross layer analyses of fixed wireless systems as Wireless Local Loop, relay networks, WiMax for fixed or repositionable...
Security in wireless networks has traditionally been considered to be an issue to be addressed at the higher layers of the network. However, with the emergence of ad hoc and other less centralized networking architectures, there has been an increase in interest in the potential of the wireless physical layer to provide communications security. Information theory provides a natural framework for the...
