Abstract In this paper we investigate the impact of node mobility in a wireless ad hoc network (WAHN). Especially we investigate the possibility to provide guaranteed services in a WAHN, i.e., the network topology predictability. We combine link expiration time (LET) estimation with information propagation speed (IPS) in a time-space diagram and as result an operation area is revealed. The result gives that a WAHN, where the nodes are mobile, has a knowledge horizon (KH), the distance of which is dependent on the mobility of the nodes. Beyond the KH, knowledge about the network state is impossible to achieve. Thus, we can not predict long distance network topology state when the node mobility is high.
