\n
Dynamic spectrum sharing aims to provide secondary access to under-utilized spectrum in cellular networks. The main aim of the talk is twofold. Firstly, the secondary operator aims to borrow spectrum bandwidths under the assumption that more spectrum resources exist considering a merchant mode. Two optimization models are proposed using stochastic and optimization models in which the secondary operator (i) spends the minimal cost to achieve the target grade of service assuming unrestricted budget or (ii) gains the maximal profit to achieve the target grade of service assuming restricted budget. Results obtained from each model are then compared with results derived from algorithms in which spectrum borrowings are random. Comparisons showed that the gain in the results obtained from our proposed stochastic-optimization framework is significantly higher than heuristic counterparts. Secondly, post-optimization performance analysis of the operators in the form of blocking probability in various scenarios is investigated to determine the probable performance gain and degradation of the secondary and primary operators respectively. We mathematically modelled the sharing agreement scenario and derive the closed form solution of blocking probabilities for each operator. Results showed how the secondary operator perform in terms of blocking probability under various offered loads and sharing capacity.\u00a0<\/span><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
