A method for finding and reserving bandwidth in multihop mobile wireless networks is disclosed, which first finds the common free slots of all the links on a path, and marks the common free slots as 'available' slots. Then, the slots among the common free slots which are not on the same positions in the TDMA frame as the common free slots of the downstream and upstream links for each link are found and marked as 'reservable' slots. The current bandwidth of a link is defined as the current number of reservable slots on the link. Next, An iterative process is performed to try to increase the bandwidth of the link having the smallest current bandwidth such that the bandwidth of the path can be increased.

Method for finding and reserving available bandwidth in multihop mobile wireless networks

There is disclosed a double-threshold admission control method in cluster-based micro/picocellular wireless networks. The method provides a cluster level threshold and cell level threshold. When the number of occupied channels in the cluster is less than the cluster level threshold and the number of occupied channels in the cell is less than the cell level threshold the mobile user is admitted to enter a cell. Otherwise, the mobile user is refused to enter the cell.
