Geometric Dynamic Channel Allocation as a Practical Strategy in Mobile Networks with Bursty User Mobility

The interference-free, timid, not-conditioned class of Dynamic Allocation Channel Allocation strategies are examined to verify if to and what extent strategies belonging to this class can offer better performance compared to Fixed Channel Allocation (FCA). In this framework, a simple but attractive DCA strategy called Geometric DCA (GDCA) is proposed. It is found that the proposed GDCA allows better performance than more sophisticated strategies already proposed. Results obtained also show that DCA strategies in the considered class cope with large and sudden traffic fluctuations remarkably better than the FCA scheme does and that the advantages becomes more evident as the burstiness of the user mobility process increases.
