Applying NEMO to a Mountain Rescue Domain

Abstract

In an effort to provide a solution to the problem of internetworking mountain rescue workers without the use of a fixed infrastructure, our group has explored the use of a network model based on the concept of Network Mobility and the use of the NEMO Basic Support Protocol. In this paper we consider the feasibility of this approach through the design, configuration and testing of a working example of this scenario using an implementation of the NEMO Basic Support Protocol made available to us by Cisco Systems (running on their 3200 Series Mobile Access Router platform). We provide the results from performance testing carried out over our testbed that highlights the real impact of the scalability problems of the NEMO Basic Support Protocol in a scenario which results in a nested NEMO topology. In addition we present results that illustrate the performance improvements achievable in our scenario through using the NEMO Route Optimisation (RO) solution, Reverse Routing Header (RRH).
