摘要

Mobile wireless Ad hoc Networks (MANET) can improve significantly the communication capability of Public Safety forces deployed in a mobile, unknown and dynamic environment, since they are easy and quick to deploy, do not rely on existing infrastructures and can adapt to topology changes. Their relative weakness for proposing long-distance communication can be fixed by combining the terrestrial segment with a satellite providing both remote connection with the back-office and backup connectivity for local failures. The EC FP7 MONET project aims at optimizing this integration of the satellite with MANET networks in order to fulfill the requirements of the Public Safety domain. Several points of optimization have been identified, such as routing protocols, bandwidth and network efficiency techniques. In this paper we present two optimizations: Optimized DiffServ mechanisms and Load balancing techniques adapted to dual MANET/Satellite networks. The first one is a QoS architecture adapted to MANET networks that implements DiffServ-like traffic shaping in order to prioritize the operationally important flows. The second one is a proposition to balance the satellite link traffic between the available terminals. Both solutions will undergo simulations in order to assess their performances. If the simulations are satisfying, they will be implemented within a prototype amongst other mechanism in order to test their compatibility and the overall gain in performances.
