In this paper the network capacity of a cluster-based, wireless multihop ad hoc network is derived. Such a network consists of clusters, in which one station, called the Cluster Head or Central Controller (CC) organizes the access to the radio interface of all other terminals inside the cluster. The clusters are inter-connected by so-called Forwarding Terminals. In a first step some analytical results regarding the optimum use of adaptive modulation/coding and power control in a centrally controlled cluster are derived. In a second step it is shown that the network throughput is maximized, if all forwarding data are transmitted via the Central Controller instead of using Direct Mode Communication of the Forwarding Terminals. The maximum throughput and delay of an average connection is derived analytically by calculating the average number of Forwarding Terminals involved in a connection. Taking into account the capacity of the clusters and the network topology it is determined how the total network performance can be optimized by appropriate selection of the cluster size. Finally, simulation, results are included which illustrate the high potential of cluster-based ad hoc networks in terms of throughput and packet delay.
