In nested NEMO, a multi-tunneling causes a pinball routing problem. Several solutions proposed to solve the pinball routing problem in NEMO BSP cannot be used at PMIPv6-based NEMO due to different environment such as no route optimization with CN. The authors propose a tunnel compress scheme for multi-tunneling in PMIPv6-based NEMO. The scheme consists of two parts: The first part is an inter-domain or wired Internet part. The other is an intra part of nested mobile networks. In the inter-domain part, single IP-in-IP tunnel is created by connecting an innermost entry point with an outermost exit point in original multi-tunnels.
