This paper presents a queueing analytical framework for the performance evaluation of the secondary user (SU) packet transmission with service differentiation in a point-to-multipoint underlay cognitive radio network. The transmit power of the SU transmitter is subject to the joint outage constraint imposed by the primary user receivers (PU-Rxs) and the SU maximum transmit power limit. The analysis...
In this paper, we analyze the impact of end-to-end (E2E) delay variation on stripped sessions, whose packets are distributed over multiple links of multi-mode mobile terminal (MMT). The results of this analysis signify the importance of minimized out-of-sequence (OOS) arrival of packets belonging to a stream, while traversing through multiple radio networks to reach their destination. We, then propose...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
