Mobility performance Evaluation of Mesh rOuting protocols (MEMO)¶

Experimentation Project executed by RouteK S.L. as part of Federation for FIRE integrated project and funded as Innovative Experiments by SMEs Fed4FIRE-SME-1

Project Summary¶

In contrast to traditional IP-mobility solutions (like MIPv6), which require a pre-deployed infrastructure and are limited to the coverage range of the core-backbone nodes, a fully mesh-based solution can conceptually provide a self-organized network that does not require any pre-deployed infrastructure and which’s coverage expands as nodes participate in the network. However, the performance of mesh networks in the presence of mobile mesh nodes is unclear.

This project focuses, from an experimental point of view, on the capabilities of several mesh routing protocols (Babel, BMX6, BATMAN-adv, OLSR, and IEEE802.11s) for supporting mobile mesh nodes. These investigations are of significant interest because the demand for seamless mobility has become imperative for the users.

Related experiments will be prepared using emulab - total network testbed and executed in w-iLab.t Zwijnaarde (iMinds) and Community-lab (UPC) Fed4FIRE testbeds because both of them support the configuration of wireless nodes similar to our standard deployments and are suitable to perform mobility tests.

Concept and objectives¶

The main question we are seeking to answer with this experiment is (i) if and to what extend traditional IP-mobility solutions for wireless networks (like MIPv6) can be substituted with full-mesh based solutions and (ii) to what extend the existence of mobile nodes, and thereby introduced temporary and highly dynamic links, affects the end-to-end performance of stationary nodes.

To answer this question, the objective of this proposal is to analyze state-of-the-art routing protocol solutions regarding their capabilities for supporting topology dynamics caused by mobile mesh nodes.
The mobility support will be measured by means of the maximum amount of topology changes a protocol can handle while maintaining a continuous connection between (i) a mobile node and a stationary destination node and (ii) two stationary nodes which's possible end-to-end path include links via a mobile node.
The exact metric for ranking the mobility performance of a protocol is given by a reference experiments. In addition, relevant cost factors for achieving an identified mobility performance will be captured as needed for providing a fair analysis of each's protocol advantages and disadvantages.

The main objective of our concluding analysis is to provide benchmarking results and guidelines that allow to estimate and predict to some extend the feasibility for supporting a given use case with a particular routing protocol.

Outlook¶

The project execution will officially start by June 1st and end by September 30 2014
