Quantitative Analysis of the Effect of Transmitting Power on the Capacity of Wireless Ad Hoc Networks

This paper presents a fundamental understanding regarding the effect that transmitting power has on the capacity of wireless ad hoc networks. Under the assumption that all interference is essentially regarded as noise, the authors carry out a quantitative analysis from the perspective of information theory. First, the authors answer the question "How much information can be carried per unit bandwidth over a wireless ad hoc network under a certain power assignment and nodal distribution?" they then prove that the maximum network capacity, whether in bps (bits per second) or in bmps (bitmeters per second), strictly increases with respect to the total transmitting power under a fixed-proportion assignment, and that there is a limit as the total transmitting power goes to infinity.
