Mobile Ad hoc Network MANET routing protocols and Network Mobility NEMO Basic Support are considered key technologies for vehicular networks. MANEMO that is the combination of MANET for infrastructureless communications and NEMO for infrastructure-based communications offers a number of benefits such as route optimization or multihoming. With the aim of assessing the benefits of this synergy this paper presents a policy-based solution to distribute traffic among multiple paths to improve the overall performance of a vehicular network. An integral vehicular communication testbed has been developed to carry out field trials. First the performance of the Optimized Link State Routing protocol OLSR is evaluated in a vehicular network with up to four vehicles. To analyze the impact of the vehicles position and movement on network performances an integrated evaluation environment called AnaVANET has been developed. Performance results have been geolocated using GPS information. Second by switching from NEMO to MANET .
