Recently, mobile computers have become able to commu nicate with each other by using a wireless LAN protocol, e.g. IEEE802.11 and HIPERLAN, for supporting various internet services. In case that a mobile computer changes a location with high speed, less messages are exchanged between the mobile computer and the Internet. This pa per proposes a novel routing protocol CB-WSCP for a mo bile clustered networks in which mobile computers with al most the same velocity and communication with each other by multi-hop transmission form a cluster. Here, commu nication between a cluster and a base station is available iff at least one mobile computer in the cluster is within a transmission range of the base station. Hence, it is re quired to support sporadic communication. For achieving wider bandwidth even though the cluster moves with a high speed, a proposed protocol achieves switching of gateways and updating of routing tables.
