Evaluation of Dynamic Channel and Power Assignment for Cognitive Networks
Wireless Personal Communications, 2010In this paper, we develop a unifying optimization formulation to describe the Dynamic Channel and Power Assignment (DCPA) problem and an evaluation method for comparing DCPA algorithms. DCPA refers to the allocation of transmit power and frequency channels to links in a cognitive network so as to maximize the total number of feasible links while ...

Dynamic game with perfect and complete information based dynamic channel assignment
Applied Intelligence, 2012The nodes in Ad Hoc networks compete for channels when communicating, with the features of no center and self-organization. In traditional channel assignment strategy of MAC layer, nodes do not consider the demands to channel resources of other nodes, which hinders improving the network performance.

A packet channel sharing protocol for dynamic channel assignment systems
Proceedings of GLOBECOM '95, 2002A major trend in mobile communications is the development of digital cordless telephone systems such as PHS and DECT for personal communications. These systems offer higher channel speeds than existing cellular systems, and should support data transmission as well as voice.

Mitigating Control Channel Saturation in the Dynamic Channel Assignment Protocol
Journal of Convergence Information Technology, 2011Multi-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, 1997In 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,

Multi-user detection with dynamic channel assignment
IEEE VTS 53rd Vehicular Technology Conference, Spring 2001. Proceedings (Cat. No.01CH37202), 2002We 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.

An efficient reservation-based dynamic channel assignment strategy
First International Conference on 3G Mobile Communication Technologies, 2000The 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.

Distributed dynamic channel assignment for in-building microsystems
IEEE Transactions on Vehicular Technology, 1998Several 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 ...

Fuzzy effect based dynamic channel assignment
Proceedings of ICCS '94, 2002A 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, 2002We 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.
