Computational challenges of dynamic channel assignment for military MANET
MILCOM 2015 - 2015 IEEE Military Communications Conference, 2015The 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), 2012With 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, 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 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.

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.

Asymptotic bounds on the performance of a class of dynamic channel assignment algorithms
IEEE Journal on Selected Areas in Communications, 1993Dynamic channel assignment, adapting both to traffic variations as well as to changing mobile locations, is investigated. Several ad hoc schemes of this type have been described in the literature and found to yield interesting performance improvements. However, very little is known about the performance of the optimum assignment schemes. Both upper and

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.
