Abstract: Distributed dynamic channel allocation (DCA) algorithms for wireless cellular networks are considered. Two algorithm extremes are the baseline of the investigation, i.e., an aggressive algorithm, in which channel assignments of ongoing calls may be reconfigured to make room for a new access request, and a timid one, in which reconfiguration is not permitted. It is shown that a light traffic analysis can be tractable. For that realm, performance expressions are derived, showing significant reductions in access blocking probability, when an aggressive, rather than timid, access algorithm is used. The relative efficacy of various algorithms can be analytically probed in this range. Certain aggressive algorithms are observed to attain the best performance possible. >

Local packing-distributed dynamic channel allocation at cellular base station

TL;DR: The local packing (LP) algorithm, a base station distributed dynamic channel allocation (DDCA) adapting to local traffic demands, is presented and shows that, unlike some other DCA algorithms, even when the network has a large number of channel, it maintains a favorable performance over FCA under uniform traffic in the region of interest.

- 29 Nov 1993
TL;DR: A simple but very accurate analytical model for a channel borrowing based dynamic channel assignment strategy in both one-dimensional and two-dimensional microcellular systems and shows that the effect of this decoupling causes the blocking probability so obtained to be an upper bound.

Performance analysis of dynamic channel assignment algorithms in cellular mobile systems with hand-off
TL;DR: The traffic performance bound for DCA strategies with hand-off is derived by extending the maximum packing (MP) scheme to include the hand-offs in DCA by showing that the simulation results of DDCA scheme are comparable with the analytical bounds given by MP.

A new frequency channel assignment algorithm in high capacity mobile communication systems
TL;DR: A new algorithm for frequency channel assignment in mobile radio communication is proposed which enables the calls having all their nominal channels busy to borrow channels from the neighboring cells provided that co-channel interference will not result.

Strategies for handover and dynamic channel allocation in micro-cellular mobile radio systems
TL;DR: It is shown that, based on the capacity improvement achieved by microcells, no relevant further improvement of the capacity can be realized, but that the proposed algorithm is very well suited to cope with the problems of microcells.

TL;DR: Large-scale mobile radio systems using dynamic channel REassignment switch the channels assigned to some of the calls in progress to maintain a nearly optimum separation between coverage areas simultaneously using the same channel.
