In this paper we consider the problem of binary hypothesis detection in wireless sensor networks under power constraint. The objective is to solve the resource allocation problem for this distributed detection problem and find a suitable operating point for the network. We consider the Neyman-Pearson (NP) criteria and design suitable transmission schemes and a fusion center (FC) detector, so that...
This work analyzes the throughput of Go-Back-N (GBN) in block fading, a model frequently used for slow fading wireless channels. We devise hidden Markov models and block transition probabilities for the block fading channel, allowing us to calculate the throughput of GBN with reliable feedback, as well as unreliable feedback. The advantages of this approach include generality: it applies to two-state...
In this paper we investigate the effect of asymmetric side information in discrete memoryless relay channels. The capacity of the degraded relay channel is known when side information at both the source and relay is identical. However, in many naturally interesting cases the source and relay may not have, or may not be able to exploit, exactly the same side information. This may occur either when...
