Resumo(s)
The adoption of Software Defined Networks (SDNs) in a Mobile ad-hoc network (MANET) could present several benefits, such as adaptability and performance increase. However, to assess this possibility, a simulation tool may be necessary to test new protocols and solutions in a large combination of scenarios and traffic patterns, without the need of real equipment. Unfortunately, few tools are available for wireless SDNs, and none have the ability to also support MANETs with multiple radio access technologies. While NS-3 has the ability to simulate heterogeneous MANETs, it does not support wireless OpenFlow capable devices or wireless OpenFlow channels. In this work we present a simulation environment that, besides creating an ad-hoc data plane, enables the possibility of creating wireless hybrid SDN devices capable of connecting to legacy devices, alongside with an LTE OpenFlow channel connected to an external SDN Controller (RYU). Results show that the simulation environment supports large networks with both legacy and SDN devices, although these will bear an effective running time higher than their simulation time. Moreover, when comparing to an OLSR-only network, the proposed network (with a basic path search metric) has the same or higher performance.
