We consider a diffusion-based nano-network with N spatially distributed transmitters and one receiver. While the transmitters are linked in a unified entity to perform one transmission, the receiver is large enough to be viewed as a plane. Messages are encoded into the number of nano-scale molecules. Based on these assumptions, we analyze the signal-to-interference ratio, which is based on the average...
This paper is concerned with distributed estimation in a Gaussian sensor network under the semi-orthogonal multiple access channel (MAC). Under the total transmit power constraint, an improved power allocation scheme among sensors is investigated. In the semi-orthogonal MAC, since sensors are divided into groups, the issue of power allocation can be separated into two tasks: power allocation within...
