In this article, a novel model of OFDM system in the frequency domain based on network calculus is introduced. The proposed model employs modular concatenation of selected network calculus components to represent the effect of subcarriers of OFDM system on the QoS performance. By the formulas of the proposed model, the minimum transmit power and the total number of error bits can be calculated and...
A modeling method for wireless packet networks based on network calculus (NC) theory, employing the concatenation of NC components to represent the effects of the modules constituting wireless packet networks model, is proposed in this paper. Three well-known scheduling algorithms are modified to agree with the proposed NC model. A new scheduling algorithm for packet networks is proposed in the context...
Coexistence of heterogeneous networks such as cellular, wireless local area network (WLAN), ultra-wideband (UWB) etc. brings new challenges. It is perceived that current radio resource management mechanism cannot meet the requirements of multi-radio access technologies (multi-RATs). This paper proposes a novel intelligent multi-agent radio resource management system, which is self-organized and distributed...
