Abstract

In this paper we investigate the impact of a relay node (RN) placement plan on a heterogeneous wireless network called hybrid wireless network with dedicated delay nodes (HWN*) in terms of system capacity, transmission delay and quality of service (QoS). A novel HWN* heuristic RN placement (HHRP) algorithm, which considers RN assistance & support for radio resource sharing such as inter-network traffic balancing, TD/CDMA soft handover, routing and user mobility has been implemented. A system level simulation is used to quantify the benefits of HWN* using HHRP algorithm over HWN* with other RN placement plans and multi-hop cellular networks.
