Route Optimization in NEMO Environment with Limited Prefix Delegation Mechanism

Abstract

Abstract. The 4G network will must be ALL-IP network and IPv6 is destiny. Already IPv6 has extended as Mobile IPv6 for host mobility and Mobile IPv6 is extending for whole network mobility. There are many possible mobile networks, and they would be nested as they change locations. Most serious problem in a nested mobile network is the complexity of routing path of packets, and the complexity grows as the level of nesting increases. In this paper, we propose 'limited prefix delegation mechanism', which delivers packets through the optimized path even though mobile networks are nested. We show the effectiveness of our mechanism by solved problems.

CRYPTRON: CRYptographic Prefixes for Route Optimization in NEMO

“…• Contrary to our proposal, some NEMO RO mechanisms are based on the prefix delegation [13] [14] and increase the complexity of other protocols (e.g. Neighbor Discovery) or other network elements (e.g.…”

Efficient route optimization scheme for nested-NEMO

“…NERON (Zarrar et al, 2009) and EMIP (Prakash et al, 2009) were also proposed based on MIRON. Some variations of PD are also used in Jeong et al (2004), Song et al (2006), Perera et al (2004) and Petander et al (2006). In these approaches, each MR in a nested mobile network is delegated a mobile network prefix (MNP) from the AR using DHCP prefix delegation (Troan and Droms, 2003).…”

Route optimization in network mobility: Solutions, classification, comparison, and future research directions

“…In another scheme proposed by Song et al [39], MRs advertise (like that in [38]) AR's prefix only (unlike [38]) to attached MRs that perform route optimization on behalf of attached MNNs (unlike [38]) by sending BU to corresponding CNs. Since MRs need to send BU to all CNs and track all CNs, signaling and memory requirement for the scheme is high in this scheme.…”
