| The loss of efficiency and dependability in wireless communications, caused by the increasing spectrum scarcity problem, is particularly critical for battery-powered devices such as sensor nodes. Cognitive Wireless Sensor Networks (CWSNs) arise in order to mitigate this situation by adding cognitive radio capabilities to them. However, the closed architecture and limited resources of traditional nodes represent a major constraint to perform certain required cognitive tasks. On the other hand, Software-Defined Radios (SDRs), which have the flexibility and performance needed to overcome the aforementioned limitations, currently have a power consumption too high for these networks. In this work, we propose a hybrid methodology of operation that consists of exploiting SDR technology only for those actions that strictly require its high flexibility, using traditional fixed hardware transceivers, which demand less node?s resources, for the remaining tasks. Then, we present the architecture and the main electronic components of a platform able to operate according to this methodology. This solution constitutes a significant reduction in power consumption compared with existing low-power SDRs, while maintaining the functionality needed for research in CWSNs. | |
