Dynamic channel assignment in cellular radio [PDF]
40th IEEE Conference on Vehicular Technology, 2002 Dynamic channel assignment algorithms for cellular systems are developed. The algorithms are compared with an easily simulated bound. Using this bound, it is demonstrated that in the case of homogeneous spatial traffic distribution, some of these algorithms are virtually unbeatable by any channel assignment algorithm.

Providing Dynamic TXOP for QoS Support of Video Transmission in IEEE 802.11e WLANs [PDF]
, 2015 The IEEE 802.11e standard introduced by IEEE 802.11 Task Group E (TGe) enhances the Quality of Service (QoS) by means of HCF Controlled Channel Access (HCCA). The scheduler of HCCA allocates Transmission Opportunities (TXOPs) to QoS-enabled Station (QSTA)

Analytical method to compute capacity improvement of dynamic channel assignment with power control [PDF]
, 2003 An analytical method is proposed to compute the capacity improvement of a dynamic channel assignment with power control (DCA/PC). A closed-form expression is derived to calculate the capacity of the DCA/PC, which is improved more than 150% compared with ...

A quasi-static cluster-computing approach for dynamic channelassignment in cellular mobile communication systems [PDF]
, 1999 Efficient management of the radio spectrum can be accomplished by making use of channel assignment techniques, which work by allocating different channels of the spectrum to the cells of the network in a conflict-free manner (i.e., the co-channel ...

A Useful Metaheuristic for Dynamic Channel Assignment in Mobile Cellular Systems
International Journal of Interactive Multimedia and Artificial Intelligence, 2012 The prime objective of a Channel Assignment Problem (CAP) is to assign appropriate number of required channels to each cell in a way to achieve both efficient frequency spectrum utilization and minimization of interference effects (by satisfying a number
