Energy efficiency is a critical issue of wireless devices. As the packets are broadcast to the devices in the wireless transmission media, all active neighboring devices have to spend their energy receiving the packets though the packets are not addressed to them, which is called as the packet overhearing problem. The real-world traffic trace analysis reveals that the energy cost on the packet overhearing...
Wireless sensors are key to machine-to-machine communications and serve as the basis for realizing the Internet of Things. Spectral and energy efficiencies are key parameters that determine the usefulness of a sensor. In this paper, we consider the scenario where both information and power are sent through the same wireless medium to sensors. Each sensor independently decides to switch between information...
Advancing technology has made it possible to integrate millions of transistors on a very small die and to clock these transistors at very high speeds. Power consumption has become the limiting factor for portable high-performance wireless applications. In this paper, we propose a system level technique to improve the power efficiency of the wireless receiver design. The proposed clock gating scheme...
In this paper, we evaluate network performance of non-acknowledged packet transfer in relatively large IEEE 802.15.4 network. Network under consideration contains six interconnected IEEE 802.15.4 beacon enabled network clusters in triangular topology using slave-slave (SS) bridges with CSMA-CA access. We investigate the interactions among local nodes, local bridges and remote bridges. Simulation results...
