Supporting Nested NEMO networks with the Unified MANEMO Architecture

Abstract

The NEMO Basic Support protocol is a Home Agent based technique (derived from Mobile IPv6) that permits the mobility of a network of IPv6 devices to be supported through the use of a dedicated Mobile Router. This NEMO Mobile Router accepts connections from IPv6 nodes and transparently manages any IP mobility on their behalf, which means that as well as individual hosts, a NEMO Mobile Router can also accept connections from other NEMO mobile networks. When this occurs, the inter-connected NEMO mobile networks form a highly inefficient topology known as a Nested NEMO network. In this paper we describe this concept and examine the properties of Nested NEMO networks. In particular we highlight how their communication patterns differ from typical Mobile Ad hoc Networks (MANET) and present example scenarios which demonstrate their potential application domain. We present the Unified MANEMO Architecture (UMA), a solution which has been developed in order to efficiently support these Nested NEMO scenarios. Through varying experimental testbed configurations, we provide an evaluation of the protocols performance and demonstrate how our approach is able to be deployed over the current Internet architecture without requiring any augmentation to access networks or the core Internet infrastructure.

Multihoming Support in Mobile IP Networks: Progress, Challenges and Solutions

“…In [11], the OLSRMANET routing protocol is adopted for enabling local routing among MRs of a nested network. In [12], the Tree Discovery (TD) [13] protocol is used for the formation of a tree topology among the MRs. For the establishment of local routing, the Network In Node Advertisement (NINA) [14] protocol is adopted. The Top Level MR performs the role of a gateway which is the only entity maintains the NEMO tunnel for the entire nested network.…”

Multihomed Mobile Network Architecture

“…This includes the Pinball Routing problem discussed earlier. The Unified MANEMO Architecture (UMA) [4] provides a comprehensive MANEMO-based solution. It defines two different models, the NEMO-Centric MANEMO (NCM) model, addressing the Nested mobility issues, and the MANET-Centric MANEMO (MCM) model, addressing mobility support for MANET networks.…”

“…It enables a network-based selection as described in the previous section under sub-section D. For criteria rating, a numerical scale of [1][2][3][4][5] is adapted to apply the relevant importance to each of the criteria of interest according to a static policy. Calculating the criteria weights based on the rating data was implemented using the pairwise comparison method.…”

“…To experimentally enable gateway selection functionality, we developed a simple selection algorithm. For criteria rating, a numerical scale of [1][2][3][4][5] is adapted to apply the relevant importance to each of the criteria of interest according to a static policy. Calculating the criteria weights based on the rating data was implemented using the Pairwise Comparison method.…”
