| Abstract(in English) | 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 proposed a wireless multi-hop virtua cellular system. In the multi-hop virtual cellular system, the transmitted signal from a mobile terminal is received by wireless ports distributed in a cell and relayed via wireless ports using a wireless multi-hop communication technique to a central port connected to the network. An efficient channel allocation algorithm is necessary for this virtual cellular system. In this paper, a channel allocation algorithm based on the channel segregation dynamic channel allocation (DCA) is proposed. After all multi-hop routes over distributed wireless ports are constructed, the channel segregation DCA is carried out to allocate the channels to the up / down links along the multi-hop routes. Each wireless port is equipped with a channel priority table. The transmit wireless port of each link initiates the 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 to find that the failure rate is almost insensitive to the allowable number of hops. |
