Joint beamforming and handoff for traffic improvements in wireless networks
A cellular wireless network with beamforming capabilities at the receiver is considered which allows two or more transmitters to share the same channel for communicating with the base station. A novel approach is introduced which combines the effects of the digital signal processing at the physical layer along with the network layer protocol on the overall queuing model of a cell. From this effective cell model, we find the closed form solutions for blocking probabilities of the calls and total carried traffic in the system. Our analytical as well as numerical results show that adaptive beamforming at the receiver reduces the blocking probability of the calls and increases the total carried traffic in the system.
