The topic of Interoperability between different routing protocols in wireless ad hoc networks is still an ongoing effort due to the numerous applications these types of networks can provide. In a wireless world with an increasing demand for mobility, wireless ad hoc networks and its derivatives, wireless mesh networks, wireless sensor networks and mobile ad hoc networks (MANETs), can benefit greatly from adjacent or passing through mobile networks. The problem of nodes using different routing protocols is studied in this work. We propose the use of a proactive approach for the Strip Interoperability mechanism which has proven to bridge heterogeneous networks using only layer 3 protocols. Moreover, a comparison is made with the previous mechanism through a Case Study, which delivers an improvement over network metrics. The testbed runs in real world OSs (Ubuntu Linux) and wireless ad hoc routing protocols implementations of OLSR and BMX6, both using IPv6 as a layer 3 protocol.
