—Power aware sensor networks has been an active area of research in the last decade and a lot of solutions have been proposed for maximizing the lifetime of a sensor network. However, an underlying assumption in most of the existing work is that the performance of a sensor remains the same throughout its lifetime, which is not always true. In this paper, we(More)
— This paper concerns the problem of minimizing the sum of motion energy and communication energy in a network of mobile robots. The robotic network is charged with the task of transmitting sensor information from a given object to a remote station, and it has to arrange itself in a serial (tandem) configuration for point-to-point transmission, where each(More)
In this paper we investigate how power consumption affects mobility-based coordination algorithms for multi-robot systems by explicitly coupling the control laws to the available power levels. In particular, we will consider a sensor network comprising of mobile sensors which use omni directional RF or radar based antennas for communication, with a(More)
— In this paper we connect the power consumed by agents in a network to how much they move. In other words, by moving around, the agents' power levels decrease, which in turn impacts the range at which they can sense/communicate with neighboring agents. This work constitutes the first, explicit connection between mobility and power consumption from the(More)
— In this paper, we address the issue of activity scheduling of sensors in heterogeneous wireless sensor and actor networks (WSANs), thereby proposing an energy-efficient data collection scheme in such networks. In order to extend the lifetime of heterogeneous WSANs, sensors are activated and deactivated under certain constraints throughout the network(More)
— In this paper, we propose a power-aware sleep scheduling scheme for a randomly deployed wireless sensor network comprising of sensors with varying footprints, akin to those of RF-or radar-based sensors. For this scheme, we first relate the performance of a sensor to its available power and then extend this relationship to the performance of the entire(More)
