In this book, we are going to present an E2E (end to end) solution for the principal problems that normally impact the community networks and especially Guifinet. To introduce our solution, we were investigating how the Guifinet works internally (its network hierarchy, equipment used, IP configuration and also its financial system) and also how wireless technology works and their limitations. Once we analysed and detected all the potential issues, we performed a routing performance and QoS (quality or service) simulation in order to test two experimental protocol called BATMAN and OLSR to find the most suitable routing protocol for our approach. And finally, we presented our new Guifinet network concept basing in MPLS over OLSR.
