Energy efficiency in wireless networks

[6] The recent increase in the use of wireless networks for video transmission has led to the increase in the use of rate-adaptive protocols to maximize the resource utilization and increase the efficiency in the transmission. However, a number of these protocols lead to interactions among the users that are subjective in nature and affect the overall performance. In [6], we analyzed the interplay between the wireless network and video transmission dynamics in the light of subjective perceptions of the end users in their interactions – specifically, the trade-off between maximizing the quality of service (QoS) or quality of experience (QoE) and minimizing the transmission cost. By using methods from game theory, we derived an optimized transmission scheme that allows the efficient use of traditional protocols by taking into account the subjective interactions that occur in practical scenarios.
