Popis: Cognitive Wireless Sensor Networks are envisioned to be utilized by a large number of wireless devices and for a variety of applications. This has prompted the need to research optimal data transmission schemes between the nodes to address these high demand expectations and for achieving higher throughput. Various data transmission schemes have been proposed but were restricted to having those transmissions made across a single spectrum band at any given time. In this paper, we propose having the nodes transmit their data across multiple spectrum bands and simultaneously. We further propose a Markov Decision Process approach for the optimal scheduling of transmissions on different channels in an environment where multiple spectrum bands are available. For ease of presentation and clarity, the analysis in this paper considers the simple case where each node has access to only two spectrum bands. The same method can be applied for the extended case of multiple spectrum bands.
