Optimal Channel Exploration for Cognitive Radio Networks
نویسندگان
چکیده
In this paper, the optimal channel exploration is proposed for cognitive radio networks. In the networks, primary users (PUs) utilize the channels with fixed slot structure. Cognitive users (CUs) should sense the channels within each slot. We study the relationship of the channel states between the nearby slots and range channels by the decreasing idle probabilities of all channels. Then we use stop rule to address the channel exploration problem, which makes CUs to access the optimal idle channel. The simulation results show our proposed scheme can obtain higher throughput.

Independent Spectrum Sensing in Cognitive Radio Networks
The spectrum sensing and channel access is a classic exploration vs. exploitation problem for cognitive radio overlay networks, where the secondary users access the idle portion of licensed primary users. We propose a simple architecture to separate the spectrum sensing form the channel access so that optimal sensing can be achieved.

متن کاملA Novel Multicast Tree Construction Algorithm for Multi-Radio Multi-Channel Wireless Mesh Networks
Many appealing multicast services such as on-demand TV, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. When multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. Designing a good multicast tree to route data packets could enhance the...

Multicast routing is one of the most important services in Multi Radio Multi Channel (MRMC) Wireless Mesh Networks (WMN). Multicast routing performance in WMNs could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. In this paper we want to address the multicast routing problem for a given channel assignment in WMNs. The channels...
