Existing spectrum management policies have led to significant overallocation and underutilization of the licensed spectrum. To address this issue, cognitive radio (CR) has been proposed as a promising new technology. In particular, it can be utilized to enable secondary users (SUs) to share the licensed spectrum if they do not cause harmful interference to primary users. As such, the transmission...
We consider the resource allocation problem in a structured sensor network. While new technologies are making sensors smarter, smaller, and cheaper, an emerging problem is how to allocate limited energy, radio bandwidth, and other resources to achieve efficient global behavior for high performance, QoS, and long network lifetime. Conventionally, resource allocation is treated as an optimization problem...
