Proactive channel access in dynamic spectrum networks
Open Spectrum systems allow fast deployment of wireless technologies by reusing under-utilized pre-allocated spectrum channels, all with minimal impact on existing primary users. However, existing proposals take a reactive sense-andavoid approach to impulsively reconfigure spectrum usage based solely on the latest observations. This can result in frequent disruptions to operations of both prima...
متن کاملDistributed Opportunistic Channel Acquisition Mechanism in Dynamic Spectrum Access Networks
We present a distributed opportunistic channel acquisition mechanism in dynamic spectrum access (DSA) networks. A novel graph-multicoloring algorithm is proposed for secondary networks, in which, each network makes use only of the local topology information (i.e., information about itself and its one-hop neighbors) to resolve contentions during channel access. We show that the proposed algorith...
متن کاملModeling of Channel Jamming in Dynamic Spectrum Access Networks
Dynamic Spectrum Access (DSA) network is envisioned as a promising candidate to significantly improve the spectrum utilization. Due to its specific features of the DSA, however, this network is more vulnerable to security attacks than the traditional wireless networks. And channel jamming is a one of main threats to DSA networks. So far, limited works have been done in mathematical and formal m...
متن کاملSpectrum Sharing In Dynamic Spectrum Access Networks
A study by Federal Communication Commission shows that most of the spectrum in current wireless networks is unused most of the time, while some spectrum is heavily used. Recently dynamic spectrum access (DSA) has been proposed to solve this spectrum inefficiency problem, by allowing users to opportunistically access to unused spectrum. One important question in DSA is how to efficiently share s...
متن کاملDynamic Spectrum Access Strategy for Multi-Channel Cognitive Radio Networks
In this paper, we present a dynamic spectrum access strategy to reduce the average overall system time of secondary users (SUs) in multi-channel cognitive radio networks. Before transmitting a packet, SU senses the spectrum environment. If there are free channels in the system, SU randomly selects one for transmitting. If all the channels are busy, we consider a probability-based spectrum selec...
