Resource allocation is an important issue in wireless communication
networks. In recent decades, cognitive radio-based networks have
garnered increased attention and have been well studied to overcome
the problem of spectrum scarcity in future wireless communications
systems. Many new challenges in resource allocation appear in
cognitive radio-based networks. This book focuses on effective
resource allocation solutions in several important cognitive
radio-based networks, including opportunistic spectrum access
networks, cooperative sensing networks, cellular networks,
high-speed vehicle networks, and smart grids. Cognitive radio
networks are composed of cognitive, spectrum-agile devices capable
of changing their configuration on the fly based on the spectral
environment. This capability makes it possible to design flexible
and dynamic spectrum access strategies with the purpose of
opportunistically reusing portions of the spectrum temporarily
vacated by licensed primary users. Different cognitive radio-based
networks focus on different network resources, such as transmission
slots, sensing nodes, transmission power, white space, and sensing
channels. This book introduces several innovative resource
allocation schemes for different cognitive radio-based networks
according to their network characteristics: Opportunistic spectrum
access networks - Introduces a probabilistic slot allocation scheme
to effectively allocate the transmission slots to secondary users
to maximize throughput Cooperative sensing networks - Introduces a
new adaptive collaboration sensing scheme in which the resources of
secondary users are effectively utilized to sense the channels for
efficient acquisition of spectrum opportunities Cellular networks -
Introduces a framework of cognitive radio-assisted cooperation for
downlink transmissions to allocate transmission modes, relay
stations, and transmission power/sub-channels to secondary users to
maximize throughput High-speed vehicle networks - Introduces
schemes to maximize the utilized TV white space through effective
allocation of white space resources to secondary users Smart grids
- Introduces effective sensing channel allocation strategies for
acquiring enough available spectrum channels for communications
between utility and electricity consumers
