Blocking probability of handoff calls and carried traffic in wireless networks with antenna arrays
In this paper we consider a wireless network with beamforming capabilities at the receiver. We derive the blocking probabilities of the calls in the system under different traffic policies for such a network. For a set of co-channel transmitters, their success probabilities for being captured by separate antenna beams are computed. These success probabilities are taken into account in the queueing model of the system. Our analytical and also numerical results show that adaptive beamforming at the receiver indeed reduces the blocking probability of the calls and increases the total carried traffic in the system.
