A Comparison of Channel Assignment Techniques with Power Control in Ad Hoc Networks
(2009)Multi-channel operation in an ad hoc network can improve robustness and reliability by ef?ciently managing interference and reducing contention. In this paper, we model four dynamic channel assignment techniques under the ... -
On Selfish and Altruistic Coalition Formation in Cognitive Radio Networks
(IEEE, 2010)We formulate the sensing-throughput tradeoff problem for distributed cognitive radio (CR) networks as a coalition formation game. Formation of coalitions enables the CRs to increase their achievable throughput, under the ... -
The Price of Ignorance: Distributed Topology Control in Cognitive Networks
(2010)In a cognitive network, autonomous and adaptive radios select their operating parameters to achieve individual and network-wide goals. The effectiveness of these adaptations depends on the amount of knowledge about the ...
