A method and apparatus that sends packets from a wireless communication device is disclosed. The method may include receiving a packet for transmission to a destination at the network layer from an upper layer within wireless communication device, determining if the packet's route to the destination can be determined within the network layer, wherein if the packet route to the destination can be determined within the layer, forwarding the packet to the destination, otherwise querying a subnet layer for the packet's route to the destination and determining if the subnet layer has determined the packet's route to the destination, wherein if the subnet layer has determined the packet's route to the destination, forwarding the packet to the subnet layer for forwarding to destination, otherwise sending a route request to the destination, receiving response to the route request from the destination, and forwarding the packet according to route specified in the route request response.
