Most experts believe that WiMAX technology is a preliminary step to develop Fourth Generation networks known as 4G technologies. It has not only succeeded in the utilization of several of the latest telecommunication techniques in the form of unique practical standards, but also paved the way for the quantitative and qualitative developments of high-speed broadband access. IEEE 802.16 Standard introduces several advantages, and one of them is the support for Quality of Services (QoS) at the Media Access Control (MAC) level. For these purposes, the standard defines several scheduling classes at MAC layer to treat service flow in a different way, depending on QoS requirements. In this thesis, we have proposed a new QoS framework for Point-to-Multi Point (PMP) 802.16 systems operating in Time Division Duplexing (TDD) mode over a WirelessMAN-OFDM physical layer. The proposed framework consists of a Call Admission Control (CAC) module and a scheduling scheme for the uplink traffic as well as a simple frame allocation scheme.
This is a tour de force analysis of the forces that drive populism by the renowned political theorist. In this highly original work, Ernesto Laclau continues the philosophical and political exploration initiated in Hegemony and Socialist Strategy. Here, he focuses on the construction of popular identities and how 'the people' emerges as a collective actor. Skilfully combining theoretical analysis with a myriad of empirical Performance Analysis and Enhancement of Qos for Fixed Wimax Networks download ebook pdf references from numerous historical and geographical contexts, he offers a critical reading of the existing literature on populism, demonstrating its dependency on the theorists of 'mass psychology' such as Taine and Freud. He, then focuses on the construction of popular identities and how 'the people' emerges as a collective actor with a political and social force, demonstrating the relation of populism to democracy and to the logic of representation and differentiating his approach from the work of Zizek, Hardt and Negri and Ranciere. This book is essential reading for all those interested in the question of political identities in present-day societies.
