Multihop routing construction for virtual cellular network

摘要

A virtual cellular system, which consists of a central port and many distributed wireless ports, was proposed recently to show that the virtual cellular system can significantly reduce the transmit power while increasing frequency efficiency. In the virtual cellular system, data relaying between central port and wireless ports is necessary. In this paper, multi-hop wireless system is applied. The virtual cellular control layer is introduced for the multi-hop transmission. A routing algorithm which minimizes the total uplink transmit power is presented. The transmit power efficiency and the number of hops are evaluated by computer simulation. It is found that multi-hop communication can reduce the transmit power of wireless port considerably while avoiding unnecessary large time delay.
