	abstract = {802.15.4 is a recent low-rate/low-power standard for wireless personal area and sensor networks. Its simple infrastructure, intermediate range and good power performance make it a candidate for applications that require a reasonably low throughput but a very high device lifetime and power efficiency. An experimental power analysis of an 802.15.4 implementation is carried out, providing a detailed power model of the protocol based on concurrent state machines; resulting power model is then used to generate a customized simulator. The model has been validated through a set of experiments and provides good accuracy; results are discussed, considering in particular use of the model as a basis for subsequent optimizations on 802.15.4 networks.},

	abstract = {In this paper we present a tool that converts specifications written with a subset of StateCharts into SystemC behavioral models. The main advantages of such an approachare rapidity of use, simplicity and reusability. Various systems can be modeled at different levels of abstraction and accuracy through StateCharts and different peculiar aspects (e.g. energy, performances) can be taken into consideration. Moreover different parts of the design can be identified at different detail levels. The kernel of the simulator is fully discussed together with its mapping to the semantics of our StateCharts diagrams. As a case study we present here a model of the IBM PowerPC 750 Cache system and the respective SystemC simulator automatically generated by our tool.},

	abstract = {Low power consumption is a critical issue in wireless sensor networks. Over the past few years, a considerable number of ad-hoc architectures and communication protocols have been proposed for sensor network nodes. If on one hand custom solutions carry the greatest power optimization potential, widespread communication standards guarantee interoperability and ease of connection with existing devices. In this paper we present a variable-granularity power model of Bluetooth, and apply it to variable-complexity optimization scenarios, to devise optimal power management policies. These policies, if backed by hardware implementations that are more power-aggressive than those available, could make the protocol fit for a wider range of sensor networks than it is today.},

	abstract = {A large number of embedded multimedia applications are characterized by high instruction-level parallelism (ILP) expecially in the most critical internal loop bodies. Very Large Instruction Word (VLIW) architectures Application Specific Instruction Set Processors (ASIP) are best suited to exploit such parallelism. Fast design space exploration and optimization of VLIW architecture to a specific application target is increasingly becoming the crucial factor to achieve higher efficiency designs in a relatively small amount of time. In this paper we propose an example of VLIW architecture application driven optimization using the VEX (VLIW Example) system. A typical image processing application, the Imaging Pipeline, has been chosen as an example.},

ANTITESYS is a EU project involving some of the major academic and industrial institutions in Europe; its aim is to foster academic-industrial collaboration in the field of embedded systems whilst forming selected students by means of a one-year master program, held at the ALaRI institute sited in Lugano, Switzerland. What makes this scenario very unique lies in the roles played by the industrial and academic partners of ANTITESYS. The two sides contribute to the training of the master students in different ways, but both share the problem of integrating remote and face-to-face meetings with the students and with the other stakeholders. In this paper, we present the requirements gathering process and the design phase of the ALaRI Intranet, plus some details about its actual implementation and some initial usage figures.},

While node-level models and approaches have been widely discussed, a problem requiring even greater attention is that of power associated with the communication protocols. We propose a high-level modeling methodology based on Finite State Machines useful to predict the energy consumption of given communication tasks with very low computational cost, which can be applied to any protocol. We use this methodology to create a power model of Bluetooth that we characterize and validate experimentally on a real implementation.},
