A Prediction-Based Flexible Channel Assignment in Wireless Networks Using Road Topology Information

AbstrAct In this paper, a novel prediction technique is proposed, which uses road topology information for prediction. The proposed scheme uses real time positioning information and road topology information, which matches with the real environment. The scheme uses flexible channel assignment to maintain a better tradeoff between forced termination and call blocking probabilities. For reservation of resources in advance, the information about future handoffs is obtained from the road topology prediction technique. To show the effectiveness of the prediction scheme and flexible channel assignment scheme, this work aims at simulation of other channel assignment strategies viz., fixed and dynamic channel assignment strategy with and without incorporating the prediction based on road topology information. It gives accurate prediction results which helps to maintain a better QoS and resource management.
