Energy Efficient Architecture to Cognitive Radio Wireless Sensor Networks

Cognitive radio has been considered as a key technology for future wireless communications and mobile computing. In this cognitive radio technology spectrum play an important role. Effective utilization of frequency spectrum improves the quality of the communication. In this paper the authors attempt to improve the radio spectrum utilization by proposing cognitive radio based wireless sensor networks. Network architecture of a sensor network plays a key factor in improving the efficiency in cognitive radio environment. Specifically they propose new spectrum aware network architecture. This paper includes also the novel hierarchical protocols along with heterogeneous and fault tolerant architecture for data dissemination networks.
