Abstract ? The emergence of nomadic applications have recently generated a lot of interest in next generation wireless network infrastructures (e.g., the 3G EGPRS (Enhanced General Packet Radio Services), UMTS/IMT-2000, etc.) which provide differentiated service classes. So it is important to study how the Quality of Service (QoS), such aspacket loss and bandwidth, should be guaranteed. To accomplish this, we develop an admission control scheme which can guarantee bandwidth for real-time applications in multihop mobile networks. In our scheme, ahost need not discover and maintain any information of the network resources status on the routes to another host until a connection request is generated for the communication between the two hosts, unless the former host is offering its services as an intermediate forwarding station to maintain connectivity between two other hosts. This bandwidth, |
