A Stochastic Spectrum Trading And Resource Allocation Framework For Opportunistic Dynamic Spectrum Access Networks, Mohamed Abdelraheem, Mohammad Mahmoud Abdellatif
Electrical Engineering
In this article, the spectrum trading problem between primary users and secondary networks is investigated. The secondary network requests multiple channels with the targeted availability to satisfy its users’ demands. Due to the uncertainty about the channels availability, stochastic optimization techniques are adopted to find the optimal set of channels for each secondary network for the lowest cost. Two different constraints on the secondary demand are defined. The first one is when the throughput has to be fully satisfied for a certain percentage of time, and the second one is when the expected value of the throughput has to exceed …

As the number of wireless devices is increasing daily, the radio frequency spectrum is becoming more crowded. Moreover, due to the stochastic nature of wireless communications technologies, some frequency bands which are allocated to services or users can be underutilized. On the other hand, some users may not be able to access the medium as all the frequency bands have been already allocated to different users. Cognitive radio has gained a lot of interest in the past few years as it tackles the problem of spectrum scarcity by taking advantage of spectrum holes that are available in the frequency spectrum. …

Underwater communication (UWC) has become an attractive research field over the past few decades. This is mainly due to the increase in underwater applications such as exploration, monitoring, and warning systems. Traditional communications techniques face many obstacles when used underwater. Optical communications require line of sight which is not always maintained underwater due to turbulence. Acoustic communication does not suffer from that, however, it can only operate with very low rates. While radio frequency (RF) communication can only operate over short distances due to the attenuation from the water, it can deliver relatively high data rates and does not require …
