Abstract

We propose a method to manage transmission power in nodes belonging to a wireless sensor network (WSN). The scenario contem- plates uncoordinated communications using impulse radio ultra wide- band (IR-UWB). Transmission power is controlled according to the sta- tistical nature of the multiple access interference (MAI) produced by the nodes in the close vicinity of the communicating nodes. The statistical nature of the MAI is a function of the node population density within the area of coverage of the WSN. We show that when the node population density is high enough transmission power savings are possible.
