Cognitive radios can utilise the idle spectrum holes that arenot occupied by the Primary Users (PUs) (i.e. licensed users) fortemporary wireless communication tasks. A challenging issue is toefficiently reach global/regional views among the Secondary Users(SUs) on channel availability. The SUs need to exchange controlmessages on their spectrum sensing results. A traditional way is tosend out 'raw' channel information from each individual node. Itconsumes much wireless communication bandwidth. This researchproposes a new cognitive radio spectrum sensing scheme based on ourproposed Spatially-Decaying, Time-Incremental (SDTI) updatingalgorithm. Our SDTI algorithm is based on the extension ofGossiping Updates for Efficient Spectrum Sensing (GUESS) schemethat adopts Flajolet-Martin (FM) aggregation to reduce data amount.Our SDTI automatically assigns weights to channel information basedon the distance between a source node and an observing node.Further, distance nodes have less important information to theobserving node.
