Distributed spectrum leasing via cooperation
… of secondary activity to perform effective spectrum sensing and on the stringent constraints on protocols and architectures. To address the problems highlighted above, the framework of distributed spectrum leasing via cross-layer cooperation (DiSC) has been recently proposed as a basic …

Optimal resource sharing and spectrum leasing in energy efficient relay-assisted networks
… the two aforementioned methods to materialize spectrum leasing and sharing for the case when the primary network is active with a certain probability. Then we investigate two different design approaches to the multi-carrier scenario. The first approach relies on maximizing the secondary network …

Cooperative retransmission protocols in fading channels : issues, solutions and applications
… for a practical implementation of dynamic spectrum access paradigm are also recognized and investigated. Detailed contributions follow. While conventionally regarded as energy efficient communications paradigms, both cooperative and retransmission concepts increase circuitry energy and may …
