Abstract: Abstract In this paper, we propose a spectrum sharing protocol wherein the sharing is performed in a situation without introducing a secondary transmitter in assisting the primary system. Specifically, in the primary system, the primary receiver after achieving its target rate helps a secondary receiver to achieve its target using the remaining power left with it. We study the optimization of power with increased QoS and Experience for both the primary systems and the secondary receivers while the former has a higher priority. Additionally Hidden Markov Model has been used for resource allocation in the proposed model to achieve high spectrum efficiency and energy efficiency. The main emphasis of the model is in an urban deployment scenario as we are heading towards ultra-dense network for next generation networks. Extensive simulations have been carried out and the results demonstrate the performance of the proposed spectrum sharing protocol in comparison to some other power allocation techniques and opportunistic spectrum sharing model. The proposed model achieves high power optimization, increased throughput and access rate along with better QoE. The results confirm the efficiency of the proposed protocol for both the primary and the secondary system.
