Weizheng Wang · Computing Technology and Automation · 2013
The performance of traditional wireless sensor network is limited with co-channel interference.With recent advances in multi-radio wireless technology,it is possible to apply the multi-channel in wireless sensor network to get better throughput.But Dynamic Spectrum Access is an important link for massive deployment of multi-radio wireless sensor network.Cognitive radio is the essential technique basis of Dynamic Spectrum Access.With the introduction of cognitive radio,wireless sensor network can get better transportation characteristics even in congested spectrum.This paper presents a novel architecture for multi-radio cognitive wireless sensor network which consists of connected dominating set.Analysis shows that proposed network architecture provides easy extensibility and fault-tolerance ability.
