XIAN: Cross-Layer Interface for Wireless Ad hoc Networks
Résumé
In the highly dynamic and unpredictable environment of MANETs, cross-layer design is receiving growing interest but lacks experimental validation tools. This paper proposes Xian, a Cross-layer Interface for wireless Ad hoc Networks, a generic interface for experimenting cross-layer designs with legacy 802.11 protocols. Xian can be used as a service by other network layers or system components to access information about configuration and performance of MAC/PHY layers. The interface is fully implemented and is available for Linux over the MadWifi 802.11 driver. We exemplify its use for the design of various QoS routing schemes and provide experimental demonstration of their potential benefits.
