Integrated cellular and ad hoc relay (iCAR) systems: pushing the performance limits of conventional wireless networks

Performance of iCAR system - a new load balancing scheme in wireless networks - is analyzed. Traffic capacity enhancement of the iCAR system with respect to the conventional cellular system, without any load balancing, is evaluated. It is shown that, with a moderate amount of relay coverage, perfect load balancing can be achieved, thus enabling the system to support maximum possible traffic intensity for a given grade of service.
