Construct the Load-Balanced Topology in NEMO

The Mobile Network (MONET) is a single network unit and can move around arbitrarily. The NEMO protocol is a way of managing the mobility of an entire MONET which changes its access point to the Internet. In NEMO, the Mobile Router (MR) acts as a central point of Internet attachment for all the mobile nodes, and it is likely to be a potential bottleneck because of its limited wireless link capacity. However, in original NEMO protocol, the MR cannot select a less loaded access router (AR) to connect to the Internet when NEMO handoff occurs. To construct a load balancing NEMO, the mechanism for choosing a suitable AR should be further studied. In this paper we propose two clustering algorithms to construct one NEMO. Further, two load balancing schemes are proposed to resolve the load-balanced handoff problem in NEMO. The simulation results show that the proposed constructing algorithms and load balancing schemes could significantly improve the performance of NEMO in terms of delivery ratio, load balancing index and host-to-host delay.
