Abstract

Non-uniform coverage is a major concern in cellular data networks based on HSDPA/HDR access technologies. Poor coverage lowers the overall utilization of the cell and results in location-dependent downlink throughput for mobile users. We focus on the planning of ad hoc relay network (ARN) in providing an improved cellular coverage. Specifically, we present and discuss issues and approaches for relay node placement in cellular space. Through extensive simulation modeling, we provide the evaluation of the improvement in the location dependent cellular data rate by employing the ARN.
