Cognitive Radio Network for Smart Grid
Recently, Cognitive radio and Smart Grid are two areas which have received considerable research impetus. Cognitive radios are fully programmable wireless devices that can sense their environment, and dynamically adapt their transmission waveform, channel access method, spectrum use, and networking protocols. It is widely anticipated that cognitive radio technology will become a general-purpose...
متن کاملSpectrum Management in Cellular Network using Cognitive ROF
-Radio-over-Fibre (RoF) is an optical communication technique based on the transmission of standard wireless radio signals though optical Fibre in their native format. The optical Fibre provides a huge bandwidth that can support a variety of wireless systems, regardless of their frequency bands, being protocol-transparent which is reflected in great network flexibility. Radio-overFibre techniqu...
متن کاملCognitive WMNs: A Distributed Mechanism for Leasing Cellular Network Bandwidth
We study flow optimization in cognitive Wireless Mesh Networks (WMN) that do not possess any bandwidth of their own, but rather judiciously lease bandwidth from a collocated cellular network (CN). We develop a distributed mechanism that such WMNs can use to optimize their traffic given their own traffic needs and the cost that the CN is charging for the use of its bandwidth. We evaluate the mec...
متن کاملAn Approach to Cognitive Network Cooperation of TV Station based Green Cellular Network
Energy efficiency (EE) is very crucial for future wireless communication systems, especially for cellular devices. Cellular network can cooperate with other wireless infrastructure for exploiting the detected spectrum holes to support energy-efficient cellular communication. TV white space (TVWS) can be used for Base station (BS) to User terminal (UT) communication with the aid of the existing ...
متن کاملSmart Antenna Beamforming Network
Smart Antenna with RF beamforming capability can greatly improve the performance of the vehicle communication system by providing better link quality and high immunity to interference. Butler Matrix is a well-known beamforming network. It can be used for multibeam antennas. The Butler Matrix increases the system capacity and provides higher signal to interference ratio, consequently enhancing t...
