Traffic Modeling and Analysis of Wireless and Mobile Cellular Systems Using Smart Antennas

As an efficient capacity enhancement technique, smart an-tenna has been introduced into wireless and mobile cellular systems. Since the traffic models for a wireless and mobile cellular system using smart antennas closely relate to users’ space locations and the parameters of smart antennas, the con-ventional traffic models for a wireless and mobile cellular sys-tem using omnidirectional antennas are not suitable for the systems using smart antennas. In this paper, we propose and analyze two novel traffic models for two wireless and mobile cellular systems using smart antennas, which are switched-beam and adaptive beamforming systems, respectively. The handoff rates of a wireless and mobile cellular system us-ing smart antennas are obtained and verified by simulations. Based on the obtained handoff rates, the performances of om-nidirectional antenna systems, switched-beam systems, and adaptive beamforming systems are compared in terms of the blocking probabilities of originating calls and handoff calls
