Popis: Cognitive wireless sensor networks exploit the spectrum heterogeneity and dynamically accesses the different spectrum bands based on the wireless medium conditions and permissions. The various spectrum access schemes proposed in the previous work have limited such access to a single spectrum band at any given time. This limitation may be insufficient for networks with a large number of nodes that are exchanging high volumes of data. In this paper, we propose a probabilistic transmission scheduling policy that allow the sensor nodes to transmit their data simultaneously across a multiple number of spectrum bands. We further present a mathematical model to analyze the performance of the sensor nodes that employ the proposed scheduling policy. The model can also be utilized for determining the optimal decision policies and parameters.
