the connection of an ad hoc network comprising mn n and mn n 1 is shown the ad hoc routing protocol here aodv is used for the connection and transmission of ip routing packets the hmip protocol stack is used for connecting mobile user terminals to the internet when these change between the ip networks for this purpose the ad hoc user terminals send the binding update bu via the base station said base station being the fa constituting the gateway between the ad hoc network and the ip infrastructure the protocol is implemented for hmipv6 only mobility anchor points map according to fig1 are provided instead of gateway foreign agent gfa and regional foreign agent rfa fig1 schematically illustrates the components of a base station bs 1 for establishing communication links in a radio communication system comprising at least a plurality of base stations bs 1 bs 2 and user terminals mn 0 mn 1 the user terminals mn 0 mn 1 are implemented as multihop capable ad hoc nodes the user terminal mn 0 attempts to establish an ad hoc communication link to the base station bs 1 via the user terminal mn 1 the base station bs 1 has a limit value definition unit lvdu for defining the.
