Analysis of Cellular Wireless Networks with Non-Classical Traffic and Channel Reservation

Abstract

This paper describes a traffic model for cellular wireless network with non-classical traffic (i.e., gamma inter-arrivals and general service times). Empirical studies have shown that electromagnetic propagation condition, irregular users’ behaviours, management policies, equipment failures, charging capacity of battery and so on have significant influence in call drops. Hence, the exponential assumption for both the inter-arrival and service times does not always hold true, as it does not represent the real dynamics involved in an operational network. The proposed Ek/G/C model takes into account the non-exponential inter-arrival time and service time distributions and gives a more pragmatic model for future cellular wireless networks. The performance of the proposed model of the cellular wireless network has been re-evaluated with channel reservation using both classical and non-classical traffic. The results show that non-classical model gives better approximation of the system performance in terms of the blocking probabilities.
