摘要：Network mobility (NEMO) is an important requirement for internet networks to reach the goal of ubiquitous connectivity. The IETF design NEMO BSP to manage network mobility in an aggregate way. Standard NEMO suffers from number of limitation and problems such as pinball problem and link-drop problem. In NEMO route optimization, an attacker may induce the mobile router to initiate the route optimization procedure with a large number of correspondent nodes at the same time by sending to a mobile network node of the NEMO a spoofed IP packet that appears to come from a new correspondent node. If the correspondent addresses are real addresses of existing IP nodes, then most instances of the binding update protocol may be successfully completed. The entries created in the Binding Cache are correct but useless. In this way, the attacker can induce the mobile to execute the binding update protocol unnecessarily, which can drain the mobile�s resources. A correspondent node can also be attacked in a similar way. The attacker sends spoofed IP packets to a large number of mobiles, with the target node�s address as the source address. These mobiles will initiate the binding update protocol with the target node. Again, most of the binding update protocol executions will be completed successfully. By inducing a large number of unnecessary binding updates, the attacker is able to consume the target node�s resources. Meanwhile, using the correspondent router will reduce this kind of attack according to its rules and function as a single point of management to optimize on behalf of multiple entities. This research provides an analytical method for evaluating the resource consumption in different NEMO schemes using correspondent router.
