| Abstract: | A new channel assignment (CA) model named optimum channel assignment (OCA) model is presented.First,the difference equations for the general CA problem is established from the features of channel assignment practice,then the OCA model is formulated and its solution is derived by using the Pontryagin minimum principle,these analytically derived results are then further validated by our computer simulations.The new model provides a fast,efficient CA algorithm,and remedies the current shortage of the overall performance evaluation for channel assignment schemes. |
