A Relay Skipping Method for a Multi-Hop DS-CDMA Virtual Cellular Network

A multi-hop virtual cellular network (VCN) was proposed for future mobile communication systems. In VCN, the transmitted signal from a mobile terminal is relayed via multi-hop links to the central port, which is the gateway to the core network. In the original multi-hop VCN, a call is blocked when there is no channel available at one link over the multi-hop route. However, the use of a sub- route when a link failure occurs can be a solution to avoid the blocking of this call. In this paper, we propose a relay skipping method to avoid the call blocking in a DS-CDMA VCN. Computer simulation is conducted to evaluate the impact of the proposed method on the blocking probability of the multi-hop VCN and make comparison with the present cellular network as well.
