A Two-Threshold Guard Channel Scheme for Minimizing Blocking Probability in Communication Networks
In this paper, we consider the call admission problem in cellular network with two classes of voice users. In the first part of paper, we introduce a two-threshold guard channel policy and study its limiting behavior under the stationary traffic. Then we give an algorithm for finding the optimal number of guard channels. In the second part of this paper, we give an algorithm, which minimizes th...
متن کاملFixed Channel Assignment Optimization for Cellular Mobile Networks
The optimization of channel assignment in cellular mobile networks is an NP-complete combinatorial optimization problem. For any reasonable size network, only sub-optimal solutions can be obtained by heuristic algorithms. In this paper, six channel assignment heuristic algorithms are proposed and evaluated. They are the combinations of three channel assignment strategies and two cell ordering m...
متن کاملA dynamic channel assignment policy through Q-learning
One of the fundamental issues in the operation of a mobile communication system is the assignment of channels to cells and to calls. Since the number of channels allocated to a mobile communication system is limited, efficient utilization of these communication channels by using efficient channel assignment strategies is not only desirable but also imperative. This paper presents a novel approa...
متن کاملAn efficient evolutionary algorithm for channel resource management in cellular mobile systems
Modern cellular mobile communications systems are characterized by a high degree of capacity. Consequently, they have to serve the maximum possible number of calls while the number of channels per cell is limited. The objective of channel allocation is to assign a required number of channels to each cell such that both efficient frequency spectrum utilization is provided and interference effect...
متن کاملComparison of Two Optimization Techniques for Channel Assignment in Cellular Radio Network
The channel assignment problem has become increasingly important in mobile telephone communication. Since the usable range of the frequency spectrum is limited, the optimal assignment problem of channels has become increasingly important. Two optimization methods, the neu-ral networks and the genetic algorithms are applied for the channel assignment problem. To avoid falling into the local mini...
