Modified Rerouting Algorithm for a Multi-hop Virtual Cellular Network

In the multi-hop virtual cellular network (VCN), many wireless ports are distributed in each VC and the transmitted signal from/to a mobile user is relayed by the multi-hop technique to/from a central port which acts as a gateway to the network. According to the long term change of propagation environment and traffic distribution, addition and removal of wireless ports are necessary in order to get the adequate network topology. Hence, the route reconstruction is an important technical issue. In this paper, we propose a modified rerouting algorithm for port addition and removal, then we analyze theoretically the time and number of messages for route reconstruction, and evaluate the transmit power efficiency by computer simulation.
