Abstract
Global assignment techniques - comprising the various forms of the dynamic channel allocation algorithms -, and local assignment techniques characterised by the algorithms taking advantage of the traffic available at the overlapping service areas -, are combined into a common algorithm for mobile radio applications. The performance analysis is carried out by means of the Monte Carlo simulation having a real cellular network as the system under study. The results show a remarkable traffic performance, substantially better than that attained by the individual techniques. An increase in the complexity due to the combination is certainly expected, but, because the local techniques are reasonably simple to implement, it is believed that the overall complexity is mostly dictated by that inherent to the global technique.
Highlights
A great many channel assignment techniques, aiming at mobile radio systems applications, have been proposed and extensively investigated in the literature [1,2,3,4,5,6,7,8,9,10], as an alternative to the Fixed Channel Allocation (FCA)
The Global Assignment Techniques (GAT) group contains the various forms of Dynamic Channel Allocation (DCA), in which an arbitrary proportion of the channels available within the spectrum are assigned on a demand basis, according to the instantaneous or mean traffic behaviour
This paper proposes the conciliation of the two distinct factions by combining Global Assignment Techniques and Local Assignment Techniques into a common algorithm
Summary
A great many channel assignment techniques, aiming at mobile radio systems applications, have been proposed and extensively investigated in the literature [1,2,3,4,5,6,7,8,9,10], as an alternative to the Fixed Channel Allocation (FCA). The researches in this area seem to have been intensified lately with the advent of the Personal Communications Systems. This paper proposes the conciliation of the two distinct factions by combining Global Assignment Techniques and Local Assignment Techniques into a common algorithm
