An end-to-end simulator for an open broadband access network

The Open Broadband Access Network (OBAN)¹ project introduces an innovative approach to establish a broadband mobile network in line with present B3G visions.This paper describes the end-to-end OBAN simulator that has been developed with the aim to evaluate and quantitatively measure performance related to user's mobility, in a scenario where security is vital and there is need to be able to perform fast handover while ensuring security.A set of meaningful performance metrics is identified and measured in the simulator at application level, to model and assess the behavior of the different proposed solutions.The first part of the paper provides an overview of the OBAN architecture and the description of the models developed to simulate it, with particular focus on secure procedures for network access and user mobility. The second part describes the reference simulation scenarios, a summary of the results achieved and the relevant conclusions.
