The outage analysis of networks with randomly distributed nodes has been mostly restricted to the case of Poisson networks, where the node locations form a homogeneous Poisson point process. In this paper, we show that in great generality, the outage probability, as a function of the density of interfering nodes ??, approaches ?????? as ?? goes to zero, where ?? and ?? are the spatial contention and...
A multiple observations based censored relay scheme has been proposed for a wireless sensor network. The relays in this scheme observe signals transmitted from multiple sensors and transmit decisions to the fusion center only if the likelihood ratios of the observations exceeded a predefined set of thresholds. This scheme has been shown to outperform the single observation based relay scheme in terms...
Cognitive radio networks have the ability to efficiently utilize the radio spectrum by allowing unlicensed users to communicate in the licensed frequency bands. Transmit beamformers can be designed by setting constraints on the interference temperature of the licensed users and signal to interference and noise ratios (SINRs) of the cognitive users. This design is however very sensitive to errors in...
