Throughput and Channel Capacity of Multi-hop Virtual Cellular Network

To reduce the transmit power while increasing a transmission data rate, authors proposed a wireless multihop virtual cellular network (VCN). Each multi-hop link needs to be allocated a different channel. This means that for the given total number of channels, as the number of hops increases, the number of channels available for each link reduces. However, the signal-to-interference plus noise power ratio (SINR) of each multi-hop link increases since the communication range of each link is shortened. As a consequence, the achievable throughput or channel capacity may not necessarily reduce as the number of hops increases. In this paper, assuming one-dimensional cell layout, the relationship among transmit power, the channel capacity, and throughput in a multi-hop VCN is discussed.
