Fixed 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 کاملA 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...

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...
متن کاملFixed Channel Assignment in Cellular Radio Networks Using a Modified Genetic Algorithm
With the limited frequency spectrum and an increasing demand for cellular communication services, the problem of channel assignment becomes increasingly important. However, finding a conflict-free channel assignment with the minimum channel span is NP hard. Therefore, we formulate the problem by assuming a given channel span. Our objective is to obtain a conflict-free channel assignment among t...
متن کاملFixed channel assignment algorithm for multi-radio multi-channel MESH networks
Recently, multi-radio mesh technology in wireless networks has been under extensive research. This is because of its potential of overcoming the inherent wireless multi-hop throughput, scalability and latency problems caused by the half-duplex nature of the IEEE 802.11. The concept of deploying multiple radios in wireless network access points (APs) has shown a promising way to enhance the chan...
