Advances in wireless communications have motivated the development of Wireless Sensor Networks (WSNs) for low-cost and easy-deployable physical and environmental monitoring. At the same time, the evolution of portable mobile devices is enabling novel fully integrated internetwork computing scenarios by making viable to opportunistically exploit Mobile Ad-hoc NETwork (MANET) devices traversing the...
Deployment of wireless sensors in real world environments is often a frustrating experience. The quality of radio links is highly coupled to unpredictable physical environments, leading to intermittent connectivity and frequent outages. Because link qualities are not predictable prior to deployment, current deterministic solutions to unreliable links, such as increasing network density or transmission...
Cognitive radio is a well motivated concept for improving the inefficient spectrum utilization and apparent scarcity that result from traditional spectral regulations. So far, most efforts in the cognitive radio research field focus on techniques for the enhancement of the amount of available spectrum under the stringent constraint of causing no harmful interference to legacy users. But communication...
