Distributed dynamic channel assignment schemes

IEEE 43rd Vehicular Technology Conference, 2002
Some distributed channel schemes for a one-dimensional cellular radio system are described. The channel assignment in the schemes proposed is based on signal strength measurements and therefore gives an improvement in capacity over schemes using reuse distance criterion for channel assignment. The proposed schemes are evaluated by simulations and their

Channel quality dynamics for wireless packet data with dynamic channel assignment

GLOBECOM 97. IEEE Global Telecommunications Conference. Conference Record, 2002
We investigate how the interference/signal quality varies over time and the effect of channel setup delay on the signal quality for wireless packet data traffic with dynamic channel assignment (DCA). It is found that the SIR/interference conditions under packet data traffic becomes uncorrelated much more rapidly than that under conventional circuit ...

A Dynamic Channel Assignment Scheme for Distributed Antenna Networks

2012 IEEE 75th Vehicular Technology Conference (VTC Spring), 2012
In this paper, we propose a dynamic channel assignment (DCA) scheme for distributed antenna networks (DANs). DANs, in which many antennas are distributed in each cell, significantly reduce the transmit power compared to conventional cellular networks (CNs).

Performance issues and algorithms for dynamic channel assignment

[Conference Record] GLOBECOM '92 - Communications for Global Users: IEEE, 1993
Performance issues and algorithms for dynamic channel assignment (DCA) in a time division multiple access (TDMA) portable radio system are considered. With DCA, a radio port can use any carrier frequency in any available time-slot to set up a radio link with a portable. The portable selects a radio port prior to channel assignment for initial access or

Computational challenges of dynamic channel assignment for military MANET

MILCOM 2015 - 2015 IEEE Military Communications Conference, 2015
The electromagnetic spectrum available for military use is increasingly crowded and scarce. The military must efficiently allocate spectrum by reusing channels to the maximum extent possible, while also limiting the number of channel changes over time for systems that require manual channel configuration. The classic channel assignment problem is often

Dynamic channel assignment and routing for cognitive sensor networks

2012 International Symposium on Wireless Communication Systems (ISWCS), 2012
With the increase of the number of wireless sensing or metering devices, the collection of sensing data using wireless communication becomes an important part of many applications. Cognitive radio technology can be used to facilitate the deployment of a bandwidth efficient sensor system.

Multibeam cellular mobile communications with dynamic channel assignment

IEEE Transactions on Vehicular Technology, 2002
We 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, 1997
We 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 Single-Row Routing Technique for Channel Assignments

2009 Sixth International Conference on Information Technology: New Generations, 2009
Channel 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.

Dynamic channel assignment in integrated-services cable networks

IEEE Transactions on Communications, 1994
Cable 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.
