A Hopfield Neural Network for Channel Assignment Problem in Cellular Radio Networks
In wireless mobile communication system, radio spectrum is limited resource. However, efficient use of available channels has been shown to improve the system capacity. The role of a channel assignment scheme is to allocate channels to calls or mobiles in such a way as to minimize call blocking or call dropping probabilities, and also to maximize the quality of service. Channel assignment is kn...
متن کاملFixed Channel Assignment and Neural Network Algorithm for Channel Assignment Problem in Cellular Radio Networks
The channel-assignment problem is important in mobile telephone communication. Since the usable range of the frequency spectrum is limited, the optimal channel-assignment problem has become increasingly important. The goal of this problem is to find a channel assignment to requested calls with the minimum number of channels subject to interference constraints between channels. This algorithm co...
متن کاملFuzzy Hopfield Neural Network Approach to the Channel Assignment Problem
This paper presents a novel approach to solve channel assignment problems by using clustering technique with Fuzzy Hopfield neural network (FHNN). Channels are regarded as data sample and cells are taken as clusters. Channels are adequately distributed to the dedicated cells while satisfying the interference constraints. The goal is to avoid the interference and serve the expected traffic with ...
متن کاملA Modiied Hoppeld Network Approach for Cellular Radio Channel Assignment
A new channel assignment algorithm using a modiied Hoppeld neural network is proposed. The channel assignment problem is formulated as an energy minimization problem that is implemented by a modiied discrete Hoppeld network. Also a new technique to escape local minima is introduced. The interconnection weights between the neu-rons are designed in such a way that each neuron receives inhibitory ...
متن کاملChannel Assignment in Cellular Radio
Kumar N . Sivarajan and Robert J . McEliece, California Institute of Technology,’ and John W. Ketchum, GTE Laboratories Incorporated. In this paper, we describe some heuristic channel assignment algorithms for cellular systems, that we have recently developed. These algorithms have yielded optimal, or near-optimal assignments, in many cases. The channel assignment problem can be viewed as a gen...
