RESUMO
Ad hoc networks are networks that operate without centralized control, whose nodes communicate through wireless links in a single or multihop way. A complex issue about ad hoc networks is the capacity estimation. The computation of how many transmissions the network can support ensuring a quality of service for its users is a difficult task due to two central aspects: the wireless medium and the multihop nature of transmissions. An analytical method to calculate the capacity through the computation of the outage probability considering both aspects is proposed in this work. This method presents advantages such as simple implementation, low computational efforts and practically indistinguishable results from those obtained through simulation. This method can be applied to many propagation environments and to any network topology. More realistic interference models and the routing issue are also described along this work
