Quality of Service in Communication Systems

Abstract

The number of mobile broadband users and the volume of the traffic generated by them incessantly escalate every year. Infonetics Research [1, 45, 46, 47 ] has shown that the number of the mobile subscribers has undergone a growth from 5.1 billion in 2010 to 6.5 billion by the end of 2014, while the number of the mobile broadband subscriptions escalated from 548.9 million in 2010 to 1.5 billion by late 2014, while the quantity of the fixed broadband subscribers do not observe any dramatic growth. The results from this research are briefly depicted in Fig. 1.1. Such a disproportional incremental trend in the mobile broadband subscriptions versus fixed and mobile subscriptions stems from the prevalence of mobile broadband smart devices, that are indeed bandwidth killers and cause grave concerns for Mobile Network Operators (MNOs) and infrastructure vendors. As such, there has been a perpetual demand for assigning more bandwidth to the mobile broadband services.
