چکیده
This paper presents a c omparison of channel allocation schemes for mobile c ellular networks. Three schemes have been evaluated: Fixed Channel Allocation (FCA), Dynamic Channel Allocation (DCA) and Channel Allocation with Space a nd Time Variations (CA STV). The third scheme uses information about mobile users profiles for getting adaptability to traffic fluctuations. Results were obtained u sing a simulation environment for mobile c ellular networks called CELSA, which implements a user mobility model based on personal, space a nd time characteristics. The results provide insight into the e fficiency of taking into account the mobile users personal profiles, the c urrent cell characteristics and the time of the day in the channel allocation algorithm.

Mobile operators are witnessing a dramatic increase in traffic spurred by a combination of popularity of smartphones, innovative applications and diverse services. As mobile traffic transitions from being voice dominated to video and data dominated, the revenue per byte for the mobile operators is declining at an unhealthy rate. To counter the traffic growth and build cost-effective networks, m...
