In this paper we study in details the optimized link state routing (OLSR) protocol for ad hoc networks. In particular, we investigate its performance by focusing the attention on its energy efficiency. To have some terms of comparison the performance are compared with those of other routing schemes. Furthermore, to improve the energy efficiency by(More)
— A lot of researches are devoted to energy-save solutions in wireless sensor networks, to face their critical limited energy budget. In this paper we propose four information delivery mechanisms and we compare their relative energy impact, in order to make communications both reliable and energetic efficient. We present a parametric model to choose the(More)
When systems are deployed in environments where change is the rule rather than the exception, adaptability and resilience play a crucial role in order to preserve good quality of service. This work analyses methods that can be adopted for the duty cycle measurement of sensor-originated waveforms. These methods start from the assumption that no regular(More)
Most often more and more citizens need the possibility to exploit free Wi-Fi service available in public area. The reliable broadband network called Lepida, working in Italian Emilia-Romagna region, and the availability of a federated service of authentication have made possible to accomplish this necessity. Furthermore a new walled garden fully(More)
