An efficient reservation-based dynamic channel assignment strategy

First International Conference on 3G Mobile Communication Technologies, 2000
The guard channel scheme for radio channel allocation in cellular networks gives resource access priority to handoff calls over new calls in admission control. This reduces handoff call blocking probability significantly at the expense of a small increase in new calls blocking probability.

Mitigating Control Channel Saturation in the Dynamic Channel Assignment Protocol

Journal of Convergence Information Technology, 2011
Multi-channel MAC protocols that rely on a dedicated control channel (CC) for data channel reservation face the problem of control channel saturation. When the control channel becomes the bottleneck, data channels are not fully utilized and the spectrum allocated for the network is not used efficiently.

A fast dynamic channel assignment algorithm for packet services in DECT

ACM SIGMOBILE Mobile Computing and Communications Review, 1997
In this paper we consider the use of DECT access for packet data services. DECT systems are characterized by a dynamic channel selection algorithm which allows to reuse the available radio resources in a flexible way. The standard channel allocation procedure results inefficient for packet data applications characterized by short and frequent messages,

Distributed dynamic channel assignment for in-building microsystems

IEEE Transactions on Vehicular Technology, 1998
Several fully distributed measurement-based dynamic channel assignment (DCA) schemes are compared for the large-scale uncoordinated deployment of in-building microsystems: DCA based on the first quality of service (DCA-FQZOS) channel selection, DCA based on best QOS channel selection (DCA-BQOS), DCA-WO (channel) (DCA with weighted channel orderings ...

Multi-user detection with dynamic channel assignment

IEEE VTS 53rd Vehicular Technology Conference, Spring 2001. Proceedings (Cat. No.01CH37202), 2002
We apply multi-user detection (MUD) techniques to a TDMA system with dynamic channel assignment (DCA). With help of the DCA, the channel covariance matrix in the MUD is avoid being ill-conditioning. On the other hand, the MUD can help the DCA to improve the orthogonality between channels of co-channel users by decorrelation.

Fuzzy effect based dynamic channel assignment

Proceedings of ICCS '94, 2002
A class of dynamic channel assignment (DCA) algorithms referred to as the fuzzy distributed DCA (FDDCA) is presented. From decision point of view, conventional DCA algorithms are global and crisp decision makers. The decision of to or not to assign a channel for an incoming call is a crisp logic evaluation over a set of crisp system constraints ...

Dynamic channel assignment strategy for microcell systems

1997 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing, PACRIM. 10 Years Networking the Pacific Rim, 1987-1997, 2002
We propose a new cochannel information based dynamic channel assignment (CDCA) strategy for small and microcell systems. We also propose a new group dynamic channel assignment (GDCA) strategy which handles multichannel traffic in wireless network.

Dynamic channel assignment in shotgun cellular systems

RAWCON 99. 1999 IEEE Radio and Wireless Conference (Cat. No.99EX292), 2003
This paper analyzes dynamic channel assignment in cellular systems where the base stations are placed at random. Using a simple dynamic channel assignment algorithm, random systems are compared to an ideal hexagonal system. Under log-normal shadow fading the random system has capacity within 1 dB of the hexagonal system.
