Dynamic Single-Row Routing Technique for Channel Assignments
2009 Sixth International Conference on Information Technology: New Generations, 2009Channel assignments in a wireless cellular network is a discrete-time event process involving the correct mapping of the channels to the caller-receiver pairs. The channels are assigned in such a way that they are constantly reused once a particular assignment is completed.

Multibeam cellular mobile communications with dynamic channel assignment
IEEE Transactions on Vehicular Technology, 2002We consider sectorized multibeam cellular mobile communications with dynamic channel assignment to beams. Network performance for space-division multiple access (SDMA) based on channel reuse between beams is investigated. We use a model to calculate theoretical traffic performance characteristics of the proposed system including call-blocking ...

Static and dynamic channel assignment using neural networks
IEEE Journal on Selected Areas in Communications, 1997We examine the problem of assigning calls in a cellular mobile network to channels in the frequency domain. Such assignments must be made so that interference between calls is minimized, while demands for channels are satisfied. A new nonlinear integer programming representation of the static channel assignment (SCA) problem is formulated.

Dynamic channel assignment in integrated-services cable networks
IEEE Transactions on Communications, 1994Cable networks can offer a variety of video services such as video-on-demand, video conferencing, videotex, and real-time monitoring, besides broadcasting TV programs. These services can be extended when optical fibers, equipping tremendous bandwidth, are used to carry the traffic.

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.

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.

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,
