    There have been strong demands for higher speed data transmissions in mobile communications. To reduce the peak transmit power while increasing the data transmission rates, authors recently proposed a wireless multi-hop virtual cellular system. In a multi-hop virtual cellular system, an efficient channel allocation algorithm is necessary. In this paper, the channel segregation dynamic channel allocation (CS-DCA) scheme is applied. After all multi-hop routes over distributed wireless ports in a virtual cell are constructed, the CS-DCA is carried out to allocate the channels to multi-hop up and down links. Each wireless port is equipped with a channel priority table. The transmit wireless port of each link initiates the CS-DCA procedure and selects a channel among available ones using its channel priority table to check. In this paper, the DCA failure rate is evaluated by computer simulation. It is found that the failure rate is almost insensitive to the allowable number of hops.
