> Sensor network technologies (like 6LowPAN) that base on IPv6 technology use topologies that require multi hop communication inside one logical network. The routing through the network is performed by protocols above the IP layer. Hence, every hop in the multi hop network requires routing. Link local scope allows a single node to reach it's immediate neighbors only. The usage of the discovery proxies to overcome this issue is not applicable because of the restricted resources of intermediate nodes.
