Spatial localization is an important building block for wireless sensor networks. Beacons that know their position and serve as reference are a vital aspect of nearly every localization system. In this paper, we look at dense beacon placement, which has a significant impact on the overall quality of localization. Based on the premise that uniformly dense beacon placement is not practical, we motivate the need for adaptive beacon activation in dense sensor networks. In this paper, we consider STROBE, a previously proposed beacon activation algorithm, and modify it to be energy aware. Our simulation results show that the addition of residual energy as a parameter in the STROBE algorithm results in a longer network lifetime and better coverage on the periphery of the network.
