A QoS-ensured transmission scheme with content-based priority for mobile cluster users

Due to the increasing number of mobile hosts and hand sets, communications between mobile users becomes popular and important. Using a mobile cluster network we could realize cooperation and resource sharing among mobile users. We propose a QoS-ensured transmission scheme with content-based priority for mobile cluster users. In our scheme some mobile hosts form a mobile cluster network, which is a kind of LAN. All mobile hosts will share the total capacities of the cluster network and the outside interface. We divide all mobile hosts into different priority degrees based on the content type of them. As a result we could realize making good use of the bandwidth resources of the total system under the condition that the arrival traffic is asymmetric. We could also realize optimizing the performance of high priority traffic under the condition that the total system lies in overload status.
