- Throughput and Transmission Capacity of Ad Hoc Networks With Channel State Information
- This paper develops a general framework for deriving the spatial throughput and transmission capacity of spatially Poisson distributed ad hoc networks for random (e.g., fading) channels, and random transmission distances. In both of these scenarios the randomness of the channels and ranges invariably lowers both throughput and transmission capacity assuming...

- Transmission Capacity of Wireless Ad Hoc Networks With Successive Interference Cancellation
- The transmission capacity of a wireless ad hoc network can be defined as the maximum allowable area spectral efficiency such that the outage probability does not exceed some specified threshold. This paper studies the improvement in transmission capacity obtainable with successive interference cancellation SIC, an important receiver technique that has...

- Transmission Capacity of Wireless Ad Hoc Networks With Outage Constraints
- In this paper, upper and lower bounds on the transmission capacity of spread spectrum wireless ad hoc networks are derived. The paper defines transmission capacity as the product of the maximum density of successful transmissions multiplied by their data rate, given an outage constraint. Assuming that the nodes are randomly...

- Really fascinating news: Virus is passed from parent to child in the DNA. Researchers found that roseola, an infection that everyone apparently gets but only 20 percent of children develop the characteristic rash that gives it its name, is actually in our DNA. It co-evolved into us, which raises some...
